I made a knucklehead move over the weekend and got one of my drill bits stuck in a piece of acrylic acetate. I think I pushed it too hard, things got too hot, and the drilled away material that was in the flute melted and then cooled and fused with the blank, wedging the drill bit in there. I couldn't get it out for the life of me--I tried pulling it, twisting it, etc. I finally was able to twist it out after flooding it with WD-40. I knew I should have pulled it out, but it was one of those "I'm close to the end so I'm just going to finish it up" decisions. I was using one of those brad-point, parabolic pen bits. I think I might try a regular jobber-size twist bit when I need a new size, as some have suggested that those tend to work better than the marketed-for-pens stuff. And, when I'm drilling resins and plastics, from here on other--other than going slow, I'm going to spritz the hole with a little WD-40. I did that for the blanks I drilled after I was finally able to dislodge my bit and things seemed to stay cooler.
Anyway, thought I'd post my mishap lest others can learn the lesson without feeling as foolish as I do.
