SOURCEONE.ORGPremium Drill Bits for Acrylic, Plexiglass, Lucite Plastics

I bought this to create air holes in an acrylic hatbox that I was using as a habitat for a pet beetle, after drilling two holes it broke— one half became stuck. When I tried to remove it with pliers it broke again. I was unable to retrieve the broken tip so I decided to trash the project and start over... I kept visualizing the piece falling and injuring the beetle or it accidentally ingesting it.. yes I am serious.

Nothing unique about the bit that makes it any better suited to plastic than any other HSS bit. I have special purpose bits for plastic that leave perfectly clean holes and this bit does NOT fall into that category. I tested this bit on 2mm thick ABS and [regardless of speed and pressure] it consistently left burrs on both sides.If your goal is produce clean holes in plastic that do not require dressing then I absolutely would NOT recommended it

Normal HSS bit. Cracks and chips acrylic on test sheet.

This drill bit is advertised as being for acrylic and plexiglass but I'm pretty sure it is just a plain old drill bit. The drill but I received was black and looked nothing like the one in the picture above. It left cracks and chips in every hole I drilled (about 8 in all) on the new plexiglass for my boat. $200 down the drain because of this fraudulent item. I should have test it on my old glass but I trusted the listing. Lesson learned. Do not buy this drill bit if you are drilling into any plexiglass or acrylic.

much thinner than i thought. cant really use it at this size

I own a sign company. I've cracked a piece of acrylic on a job site trying to use a high-quality standard bit (cost me $250 to replace the sign). But what's worse is when a well-clamped acrylic sheet gets caught in the grooves of a standard bit and the sheet spins around and nails you in the leg. This is the right tool for the job. It cuts through acrylic without the cracks or bruises. I don't know whether it's better than other specialty acrylic bits, but it worked for me.

This is a normal (though very overpriced) twist bit and is worse than useless for drilling acrylic/ plexiglass! The point angle of bits for plastic drill bits should be approximately 60deg, as is widely documented by manufacturers of that material. This bit (at least the one I received) has an angle of 126.5deg and indeed cracked the second surface of my test piece. An absolute scam, I will never buy this brand again.

this drill worked well on my plexiglass. I drilled a very small hole before using this one, but it did not break the 1/8 inch plexiglassI was drilling into.
