Conventional high speed drill bits do not work well with hard plastics such as the high quality acrylic that we use, due to the following reasons: -60 Degree bit that has a sharper point than a conventional bitåÊ -A diamond dust coating helps the tip penetrate the plastic more smoothly, avoiding chipping and cracking -Less pitch than a conventional bit -A new bit guarantees a sharp edge that will make a smooth hole without riding up the drill bit Drilling Tips: -Do NOT support the back of your screen with anything! The screen should be drilled with no pressure on it. åÊ -Drill perpendicular to the screen -Slow to medium speeds work best when working with acrylic -Let the bit do the work, try to take up to 1 minute drilling each hole -Do not try and punch through the back side, once again, let the bit slowly cut through
