1/4" Craftics Plas-Drill Bit for Plastic (Acrylics, Plexiglas, Lexan, ABS, PVC, and more)
It takes a special drill bit to properly drill through plastics. This product is ideal for Lexan, Tuffak or Makrolon polycarbonate sheet. Special 60-degree angle. Not recommended for wood or metal. NON-CHIPPING! These are specially ground flukes with a 90° point for drilling holes in acrylic plastics including, Plexiglas®, Lucite® and Acrylite® materials. Metal drill bits will not work as they are made to bite into the metal as they are pushed into it. If they are used on acrylics they will chip and cause other damage to the plastic. When drilling holes for screws, you must make the hole larger than the screw itself to allow for expansion and contraction of the material. If not, you will cause stress cracks at the hole and they will spread!
