Zero flute countersinks work well for the countersinking and deburring of holes in acrylic sheet. Precautions should be taken to protect this material from flames and high heat sources. If there are bigger "chunks" use a razor blade and scrape around the hole to remove any burrs then finish with sandpaper. A slow, steady feed rate is very important to achieve a clean, smooth hole. To prevent cracking, holes should not be drilled at a distance closer to the edge of the sheet less than 1-½ times the diameter of the hole itself. Worked perfectly. Price Price. Generally, bits with a 90° tip angle are recommended. The fly cutter and cutting tool itself must be secured properly. If the material melts, feed rate is too slow and must be increased. The previous sections dealt with controlled production and shop applications. If you just drill a pilot hole then jump right to a big size bit you will likely crack the plastic. All rights reserved. If the material chips, feed rate is too fast and must be decreased. The drill made the job of drilling acrylic plexiglass much easier. This is to ensure smooth, vibration-free drilling because large bits will tend to grab the material more. Placing a backing block of scrap acrylic, mdf, or plywood panel under the drilling point will add extra help to prevent chipping when the bit breaks through. These drill bits must be reground in order to scrape the plastic instead of sharply cutting into the material and gouging it. They also do not produce clean interior surfaces so they won't work. However, when you are drilling a ¼” hole, the recommended speed of the drill should be reduced to 1,800 rpm. In certain hole depths and sizes, coolants are necessary to prevent melting. Several manufacturers offer drill bits designed especially for plastics. for D=0.250", a coolant should be used for H>0.250"). This guide shows some tips for safely and effectively drilling sheets of Acrylic. A bit with a 90° tip angle will generate smaller chips which are easier to evacuate, reducing melting and improving hole quality. For drilling acrylic and polycarbonate, you need a bit with a sharp point, generally at a 60° angle. Authorized Chips that are molten and holes that show melting indicate that feed rate is too low or RPM is too high. If hole depth (H) is less than bit diameter (D), large chips are easily ejected. As a general rule of thumb, the recommended speed of the drill should be reduced as the size of the hole drilled increases. 1 UK only; 2. Second, the distance from the hole center to the edge of the sheet should be at least 1.5 times the diameter of the drilled hole. Be sure to … You can use a standard steel drill or an HSS drill to create your holes. A slow feed rate helps reduce the incidence of chipping. Both types of masking allow you to draw on the surface as you lay out your job. Then place a piece of masking tape over the mark. Acrylic may be stronger than regular glass, but it's still brittle! Add to list . The work piece should be held firmly or, preferably, solidly clamped to the worktable. Larger tip angles commonly cause cracking and blow out as the bit exits the sheet. According to Alison Svoboda of Boda Corporation, "polycarbonate is "notch sensitive" so a sharp drill bit is imperative. The holes must have clean crisp edges. The drill bits work well. Any commercially available, power-driven equipment is acceptable for drilling acrylic sheets. The lubricant will also help expel any of the plastic chips from the hole as you are drilling. For the best experience on our site, be sure to turn on Javascript in your browser. Coolants should also be used for holes greater than or equal to 1/2" in diameter (D ≥1/2"). A light misting of water is also recommended to keep the cutter and plastic cool, and also to act as a cutting lubricant. The holes range from 0.6mm to 3mm in 0.2 increments. In these situations, the following bit recommendations may be helpful. If used on acrylic without modification, these bits will chip and cause other damage to the plastic. See figure 1. A spindle speed of between 400-600 rpm is recommended. In particular, no warranty, whether expressed or implied, or guarantee of product properties in the legal sense is intended or implied. Thin or thick sheets. Very glad we purchased this item. They are: For drilling acrylic the recommended values for SFM and IPR are given in the table below. The special tip design carves through the plastic (not for use with wood or metal). Use a slow feed rate when starting the drilling action to allow the bit to enter the material and also slow the feed rate as the bit exits the bottom surface to prevent chipping. Do not try to pull it out. Careers; Locations; Ask a Plastics Expert; Cart Item Added Go To Cart. This includes portable drills, drill presses, lathes, automatic multiple-spindle drilling units, CNC routers and machining centers. Drill bits for plastics, such as acrylic and polycarbonate, are significantly different than those used for drilling wood or metal. Sign in to access your web account. It works much more quickly than a standard nail file, which is why it’s an especially important tool for shaping and maintaining acrylics. Sam R. October 8, 2019. A standard drill bit typically is at flat 120° angle. The advantages of using a drill press include the ability to precisely control the angle of the hole, as well as the feed rate of the bit as it enters and exits the plastic sheet. Specially designed bits are required. Holes which may be subject to forces from screws or bolts should be deburred with a countersink. Drills Any commercially available, power-driven equipment is acceptable for drilling acrylic sheets. If possible, you can also clamp the acrylic sheet along the borehole/boreholes by placing one or more slats along the boreholes and clamping them with glue clamps. Do not remove the surface protection masking prior to fabrication. I used a 1/8 bit to pierce the acrylic then stepped up with standard bits, which seems to work fine. ACRYLITE® Sheet Distributors may also offer materials and equipment. Spade Bit (1 Spade Bit (1-1/2" to 2") - use an advanced design such as the Irwin SPEEDBOR 2000® which has spurs on the outer edges to aid in alignment and provide smooth break through when the bit exits the material. A backing piece of wood or acrylic will make a neater hole. Circuit board drilling is a special case where automated machines drill thousands of tiny holes at very high speed. One difference between the types of drill bits is the angle of the tip. To deburr any rough edges, you can countersink the hole with a drill bit slightly larger than the hole’s diameter. Use a blunt metal drill or back off the rake angle. First you need to drill a small diameter pilot hole to get started. Increasing bit tip angle decreases the size of generated chips, facilitating chip ejection. Roehm America LLC Acrylic Products 1796 Main Street Sanford, ME 04073 USA Phone +1 800 631-5384 www.acrylite.co. The cutting edge must be ground “flat” to a 0-4° rake angle. Do not force the bit into the acrylic let it cut under its own weight and should the drill bit get stuck in the platic sheet, put the drill into reverse to get it out. The scrap sheet of material relieves any pressure on the plastic, which minimizes chipping and cracking. grades. Place the 1x4-inch piece of wood across the acrylic sheet and secure the plank to the top of the acrylic sheet by clamping one pair of self-locking pliers to each side of the acrylic sheet. Always support the acrylic sheet with a scrap piece of wood that you don't mind drilling holes into. Is it any more difficult to drill 1" thick acrylic compared to 1/2"? ACRYLITE® sheet usually burns rapidly to completion if not extinguished. The tip must scrape the acrylic, not gouge it. If the drill bit is new, wear it in a little on a scrap piece of wood so that there is no risk of the sharpness tearing the acrylic. Manual drilling operations should be performed at slower speed and feed rates than automated or CNC drilling taking into account the diameter of the bit, material thickness, and ability to cool during drilling. Hole finish can be used as a guide for appropriate feed rates once the correct RPM is established. Test Methods: Mechanical Properties of Plastics.). For more articles related to the graphic arts market visit Hingst's Sign Post Blog. Coolants reduce generated heat, and therefore improve hole quality. They require maximum support behind the sheet during use to prevent cracking. If you try to drill a sheet of acrylic with conventional metal or wood drill bits, there’s a chance you’ll end up cracking it. 2. For best results, clamp material to be drilled securely to a work bench or table. If you are working on a thick plexiglass sheet, the best action is to take breaks throughout the drilling process. These bits have a different geometric structure that is designed to puncture acrylic more easily and they are less likely to melt plexiglass. This modification is standard on most high quality twist drill bits. Paper and film masking prevent damage to the sheet. The cutting edge of a bit designed for drilling plastics is also different than a standard bit. T&C's apply. Using the wrong type of bit can result in the tool grabbing as you are drilling, which can lead to chipping at the edge of the hole. This includes portable drills, drill presses, lathes, automatic multiple-spindle drilling units, CNC routers and machining centers. You should also back up the plastic piece with a scrap of plywood or MDO. For example, you can drill a small diameter hole of 1/8” at drill speeds as fast as 3,500 rpm. Standard point drill bits grab too much and chip the hole edges. These measures include drilling a pilot hole first. These products are sold under the registered trade name ACRYLITE® in the Americas and under the PLEXIGLAS® trade name on the European, Asian, African and Australian continents. Please see the picture to the right for a detailed diagram. Like other plastic materials, ACRYLITE® sheet is subject to crazing, cracking or discoloration if brought into contact with incompatible materials. When drilling holes to support sheet by point fastening, there are two rules that apply. Not sold online Available online Out of stock online. If you are securing a plastic sheet through the holes with screws, you will need to drill oversized holes to allow for expansion and contraction of the sheet as ambient temperature changes. Additionally there are times that holes need to be made, such as at a job site, where there is limited control of the exact speeds and feeds that are being used. For H>D, peck drilling, drilling in increments and removing the bit from the material periodically to clear chips, should be employed. Helix angles, which are too large, can cause cracking around the hole edges. The cutter bit must also be modified to accommodate the material properties of acrylic. In most instances, when drilling an acrylic material, you will use a tool commonly known as a drill bit, which also varies in size. These factors, if not accounted for, can cause the material to melt and gum, giving less than optimum hole quality. If chips are crumbly and the cut is uneven, the feed rate is too high or RPM is too low. It is difficult to precisely control feed rate in manual drilling operations. I didn’t even know you could get drill and tap combined. The good thing with this technique of material fabrication is that it makes it possible for you to attain relatively uniform holes. Always drill the hole 1-2 mm larger than the fastening (i.e. As indicated in the graphs and table above, lower SFM’s are required for larger drill bits. If the sheet is thin, use a step drill bit instead. Step 3 Put on your safety glasses and secure the drill bit into the chuck of the drill motor. {{cart.count}} Get a Quote. Catherine G. October 8, 2019. When drilling acrylic be sure to use a good quality HSS drill bit. It is therefore essential to reduce generated heat and to remove chips quickly. Unibit® or Vari-Bit® Step Drill (1/8" to 1/2") - these bits can be used for sheets up to 0.118" (3 mm) thick to achieve a variety of hole diameters with a single bit. Drill with normal speed and a spray bottle full of water to keep bit cool. Bit geometry affects the quality of drilled holes since it affects chip size and chip evacuation. Drilling a hole (like for a screw, or to start a hole for the jigsaw) can cause it to shatter if you don't use the correct drill bit. The surface behind the cutting edge must be ground away to clearance angles of 12-15°. Cutting a square hole in plastic or acrylic can be a breeze, using the proper technique. 0 Reviews. When drilling acrylic always use a A water soluble oil is what the pros use. Metal-working high-speed steel twist drill bits can be used with some modification. (Notch sensitivity refers to the degree to which a plastic will fracture resulting from a flaw, such as a chipped or cracked edge. Best drill bits for use on a plexiglass … Several drill bit geometries are described below that can be used with success, although most do not leave the inside diameter of the hole with a smooth finish. This point angle must be ground to 60-90°. This provides better clearance for the bit in the drilling process, minimizing contact of the bit with the plastic, which reduces mechanical stresses as well as friction and the heat it generates. The material should also be placed as close to the fly cutter as possible to reduce the distance the cutter has to travel. 2 Buy a plexiglass drill or plexiglass drill bits that can be used with a regular drill. See Figure 2. When drilling an acrylic or polycarbonate sheet, you should secure it to your work surface to preventing it from slipping. Zero flute countersinks work well for countersinking and deburring holes in acrylic sheet. Small helix angles interfere with chip ejection, increasing melting. Be sure to firmly chuck the drill bit in the cordless hand drills or drill press. It has an advantage over a spade bit because it has a helical flute design which will pull out chips. As a result, feed rate must generally be slowed down in order to prevent chipping and consequently spindle speed must be reduced to prevent melting. If you’re working with a thick piece of acrylic, you can use conventional drill bits if you first place a piece of masking tape over the area to be drilled. Larger diameter bits and bits with smaller tip angles produce larger chips. and get all the latest news, trends and offers straight to your inbox. However, it implies no liability or other legal responsibility on our part, including with regard to existing third party intellectual property rights, especially patent rights. Taking breaks allows the plexiglass to cool thus reducing the risk of damage. Friction between the bit and the material also increases because of acrylic’s relatively low thermal conductivity and high thermal expansion coefficient, which cause the material to expand. If a countersink is unavailable, use a drill of larger diameter than the hole and deburr the rough edge on the exit side of the hole (side where the drill came through the sheet). For instance, if the acrylic is 5mm thick, then the distance from the edge where you will drill is 10mm. ACRYLITE® sheet is a combustible thermoplastic. They are useful for rough passage holes for installation of HVAC, plumbing or electrical wiring. To drill a hole in ACRYLITE® sheet greater than 1” (25.4 mm), a circle cutter may be used. Appropriate drilling conditions are a combination of both spindle rotation speed (RPM) and feed rate (IPM). Even a small hairline fracture will result in a crack at some point." The drill press provides the uniform pressure and constant positioning essential for a safe drilling of quality holes. Tip angles on standard drill bits are commonly 118-130°. Sign In. This allows for adequate clearance for thermal and moisture expansion and contraction. Water, kerosene, mineral oils and other compatible solvents can be used. Be sure to follow the manufacturer’s safety recommendations for equipment and materials used with ACRYLITE® sheet. Welcome Back! When drilling ACRYLITE® sheet, heat is generated due to the close clearance between the bit and the hole walls and because of the difficulty of chip ejection. This information and all further technical advice is based on our present knowledge and experience. When drilling plastic, the larger the hole, the slower drill speed you should use since high speeds can melt the plastic. Reference to trade names used by other companies is neither a recommendation, nor does it imply that similar products should be used. They leave a poor finish on the inside hole. When the hole has been completed and the “blank” has freed itself, turning the drill press off without removing the cutter, is desirable in order to prevent any chipping of the hole during tool exit. Also, always reduce the drill speed as the drill bit exits the material. Additionally, peck drilling should be employed in deeper holes to reduce melting. There are three points to consider when modifying a standard metal-working twist drill for plastics: 1. Cutting tool must only be extended enough to achieve the desired depth of cut. Understanding this information is invaluable for many hole making requirements. It takes a special drill bit to properly drill through Plexiglas, Lucite, Acrylite, or Perspex acrylic sheet. Air or liquid coolants should be used whenever possible. This will prevent chipping of the bottom surface. These metal drill bits have ground flukes with 90 degree points and 0 degree rake. These materials may include cleaners, polishes, adhesives, sealants, gasketing or packaging materials, cutting emulsions, etc. Step 4 The shape of chips generated from drilling can serve as a guide for drilling conditions. This allows for adequate clearance for thermal and moisture expansion and contraction. Special Hi-Molybdenum tool steel, gold surface treated body, flute and point for maximum lubricity. Tangee always provides excellent service. Never attempt to use a circle cutter with a hand-held electric drill. Specialty drill bits for acrylic use 60 or 90 degree points with zero rake cutting angles. First, place the plexiglass on a thick piece of scrap wood you won’t mind drilling into. Holes that may be subject to force from screws or bolts should be deburred with a countersink. 1-800-553-0335. Bits with 60° tip angles are also used, especially for holes with diameters of 1/2" and greater. If you are drilling through several sheets of plastic, you will most likely need to use some type of coolant, such as water, to dissipate the heat that will build up. Röhm GmbH and its affiliates are a worldwide manufacturer of PMMA products sold under the PLEXIGLAS® trademark on the European, Asian, African and Australian continents and under the ACRYLITE® trademark in the Americas. When you have a hole saw attached when it pulls in its going to slam against the acrylic and chip and in some cases shatter the acrylic on thinner walled tanks. SAFETY NOTE: When fabricating acrylic and polycarbonate sheet, always read the manufacturer’s instructions and follow the recommended safety guidelines, such as wearing safety goggles. I need to drill precision holes in 3mm to 12mm" thick acrylic. However, liquid coolants provide more cooling, as the liquid can trickle down the hole as the bit goes through the material, resulting in better hole finishes. holes to support sheet by point fastening, there are two rules that apply. Offar expiras 23:59(GMT) 10/02/16; 3. When drilling a stack of acrylic sheet (1/4" thick or greater), use water as a cutting fluid. Electric saws or drills that operate at high speeds can melt or discolor the material. Bits with a moderate helix angle aid in chip ejection and are recommended for drilling of plastics. Spade drill bits can also be used with satisfactory results. When drilling larger holes in a thicker piece of plastic, you will need to take additional precautions. 1” holes should be drilled no faster than 450 rpm. The gradually go up in drill bit sizes until you reach your desired diameter. Any difference in technique? This is very interesting, I recently built a box with acrylic sheet, it was 5mm thick sheet and I was drilling and hand tapping 2mm threads edge on! JavaScript seems to be disabled in your browser. Drill bits are made of high-speed steel (HSS), cobalt, HSS with carbide tips or solid carbide. First, the bolt hole diameter should be at least 2 times the diameter of the bolt. Acrylic and plastic are soft materials by nature, and power tools should be used with care. when your using a hole saw pre drill the guide drill hole first when you don't have a backing under where your drilling because when it hits through the opposite side its going to pull the bit in. The products of combustion, if sufficient air is present, are carbon dioxide and water. Also use a smaller diameter drill bit to pilot drill the … Standard metal-working drill bits are designed to aggressively cut into metal as they are fed into it. For the best experience on our site, be sure to turn on Javascript in your browser. it should only take a few seconds to go through 3/8" thick acrylic. Not only does this practice prevent the accumulation of debris resulting in the drill bit from binding in the hole, but it also avoids the build-up of heat and melting of the plastic. Super CHIPFREE point is precision ground at a 60 degree angle for gradual penetration to avoid cracking and chipping of the acrylic material. This back relief reduces metal/plastic contact and heat build-up. The helix angle on a bit is the angle between the cutting edge and a vertical line along the center of the bit. The back relief angle of the cutting edge should be ground away at a 10° to 15°. Acrylic chips can easily fly off during drilling and be a health hazard. Drilling into plexiglass requires a few additional steps that are not found when drilling into wood or metal. Next, mark the location of the hole with either a grease pencil or permanent marker. However, as mentioned above, if the tip angle is too large, larger than 90°, blow out and chipping may be a problem when the bit exits the acrylic. Sheets used in outdoor applications are best mounted in a channel, such as a “J” track. Two parameters are usually employed for determining these. Drilling Holes in Acrylic. What’s more, use of a lubricant will result in a smoother finish of the hole. Here is a video on how to properly drill through acrylic plexiglass. The water acts as a coolant, helps to reduce heat build up, and creates holes with smoother walls. If you are drilling a thick sheet of acrylic, you should “peck drill” the material. Place the sheet on a flat surface that supports it well and which the drill can run in to, for example, a wood board. As the depth of the hole increases, i.e. To make it easier to … NOTE: To prevent scratching of the acrylic or polycarbonate sheet, you should not remove the surface protection masking, until you have finished fabricating the material. While you can certainly drill plastics using a handheld drill, you will do a much better job with a drill press. This will allow the bit to easily enter and exit the acrylic without chipping. Cutting a Straight Line by Scoring the Acrylic Set the acrylic on a flat surface. For instance, you can drill mounting holes in items, such as plaques, certificate covers, control panels and signs, which enable you to attach the product to another surface using screws or other hardware. This cutting edge will scrape the acrylic, not gouge it. It is best to backup the piece being drilled with acrylic, other thermoplastic sheet or medium density fiberboard (MDF) so the drill bit will continue on into solid material as it penetrates the bottom surface. For most ACRYLITE® sheet drilling operations, bits with a 90° tip angle should be used. may chip the back side of the acrylic. Brad Point Bit (1/8" to 1") - this design is similar to a twist drill with a modified tip similar to a spade bit with spurs. As a general rule, coolants should be used when the depth of the hole (H) exceeds bit diameter (D) (e.g. White, colors, clear acrylics, cast, AR, LD etc. screw or bolt) to allow for thermal expansion and contraction. Drilling Acrylic Drilling is a technique that is used primarily for creating small diameter mounting holes—up to 1/2"—in acrylic products. Feed rate and RPM recommendations are provided in figures 8 and 9. These bits require the same considerations for support behind the sheet and for cooling as previously reviewed for twist drills bits. When drilling acrylic, it is important that the sheet is well supported. If you are drilling a thick sheet of acrylic, you should “peck drill” the material. 3. Acrylic Plexiglass sheet, rod, tube - in stock - at large plastic supplier. I used a modelling drill in a stand to ensure that I got perfectly perpendicular holes, I used hand taps with a little Vaseline. However, in many fires sufficient air will not be available and toxic carbon monoxide will be formed, as it will when other common combustible materials are burned. H>D, larger chips become more difficult to eject because of the close clearance between the bit and the hole walls. Start with a small drill bit (See link below to pilot holes) and work up to the size you require. We urge good judgement in the use of this versatile material and recommend that building codes be followed carefully to assure it is used properly. Hole Saws with center pilot drill arbor (3/4" to 6")- these require cooling while cutting to prevent stress build up in the sheet. Very excited to have some of my old music up on Spotify finally. Plexiglass, Lexan, Plastic Drill Bits These are the bits you need for drilling Plexiglass, Lexan polycarbonate, PETG, and other clear plastics. Plastic drill bits can drill through plastic. As mentioned above, chip ejection becomes more difficult as the hole gets deeper. Continuous drilling causes excess heating which melts and damages the sheet. The back relief angle of the cutting edge ensures that the drill bit designed for plastic shaves slivers of material rather carving away large chips that could propagate cracks. Copyright © Roehm. Please see the picture to the right for a detailed diagram. See the Tech Briefs in this series for more information, or contact your ACRYLITE® sheet Distributor for information on a specific product. Cf. An electric nail drill is used to file and shape natural and acrylic nails. Have Acrylic cut to size at Curbell Plastics. These bits come in a variety of diameters at home improvement or hardware stores. What this means is to drill a little of the hole at a time, repeatedly removing the bit from the hole to extract the shavings. ACRYLITE® sheet must be adequately supported and clamped to prevent flexing or vibration during the cutting operation. Optimum conditions result in smooth surface holes with smooth, continuous chips. Second, the distance from the hole center to the edge of the sheet should be at least 1.5 times the diameter of the. See figure 3. The customer is not released from the obligation to conduct careful inspection and testing of incoming goods. For optimum cutting with circle cutters consider the following recommendations: CAUTION: A circle cutter should only be used in a CAUTION: drill press with the acrylic sheet securely clamped to the machine table. Care must be taken at the points of entry and exit. First, the bolt hole diameter should be at least 2 times the diameter of the bolt. We reserve the right to make any changes according to technical progress or further developments. Before drilling, it’s best to clamp down the plastic securely to a solid surface and back up the piece you are drilling with a spare piece of plywood underneath. If you're going to be cutting a lot of acrylic or are using very expensive (thick) material, you need to invest in a blade specifically designed for cutting plastics and laminates. The suppliers listed below offer materials and equipment tested and approved by Roehm America LLC. Typically a helix angle of 15-30° is recommended. 7pcs Ceramic Nail Drill Bits Set Pedicure & Manicure Drill Bits Kit Replacement Drill Bits for Electric Nail Drill Machine Acrylic Nail Tool.
