For drilling plastic (especially plexi), this is a must!

[G-force]

I've always had trouble with huge burrs whenever I drilled ABS. And when I drilled plexi, I got lots of cracking unless I went very carefully, and went every size up to the point I needed.

On break at work today, I saw this article in a woodworking magazine. Risking it, I snapped a pic of the page when nobody was looking. (I carry a little camera around just for things like this)



I missed the bottom part when I took the pic. Basically, you just make file the edge on your drill bit to make it flat, and that solves the problem. I havent tried this myself, but I'm thinking I might go get a cheap drill set and give it a shot.

You're welcome. If I get fired, it was well worth it to help you guys out.

You'd get fired for taking a picture of a magazine on your break?

That sucks.

So, what, I just file my drill bit down? That's it?

Also, my dad puts tape on the plastic when he drills it, and it helps prevent cracks.
