i'm looking to do this http://www.youtube.com/watch?v=iOtli8s0HZA&feature=related and wanted to know what a good drill bit to do that with would be. i'd think a normal metal cutting drill bit with the twisted groove pattern would bounce around and try to get caught up and try to wear away spots. i was looking at some drill bits that had ground up diamonds in the tip that was a rounded flattened end like you would see with a hobby kit. he's using a hobby kit type die drill. i only have a cordless 18volt dewalt drill so i was planning on using that but those bits i was looking at on harbor freight were on backorder right now.
