My drill bits chip up the plexi/acrylic when I drill holes. Isn’t there a better way?
(courtesy of Cold Dog) Though pricey, I highly recommend the plastic drill bits over at US Plastic. I bought all the sizes from 1/4″ down and they leave a nice clean hole. Using a regular drill bit is not too bad if you are drilling with a 1/8″ drill bit or less but going larger and it starts to become chip city. If you must use regular drill bits, start small and work your way up one size at a time. Though I haven’t tried it, one recommendation I’ve heard of is to flatten the cutting edge on a regular drill bit and supposedly it won’t chip the plexi. Might extend the life of those old, worn out drill bits… A: The Craftics Plas-Drill bits are quite nice. They have a 90° face angle and do quite nicely in a drill press. Pros use custom ground bits with diamond dust impregnated on their surface. The Craftics are quite adequate for DIY use.
