DO NOT HAND DRILL!! Seriously, don't use a pin vise with these, you'll snap bits left and right. I put it into my dremel and am having no problems at all anymore. I just put 100+ holes into the Millennium Falcon cockpit without incident.

Bought these to make pinholes in camera body caps for pinhole photography. So far so good, using them in variously a conventional drill press and in a dremel drill press haven't broken any drilling into plastic roughly 0.5mm thick.

Not sure what the other review is talking about. I am using these for a crafts project with a high speed dremel. If you keep the dremel steady and don't ad side pressure, they work wonderfully. I bought an assorted pack from this seller too. They also worked great!

I purchased these to drill holes in plastic for a model i am building. Just sat down to use them and broke 4 bits in one hole. They broke trying to remove the bit from the hole. Save yoyrself the headach and buy a different brand these suck!
