i have burnt up Hilti jobbers, bosch titanium, etc. I was talking to a locksmith friend of mine and he swears by the Japanese. He said they are dirt cheap, but as long as they are sharp they will get the job done.

Not sure about the twist drill bits but I was wandering around in HK last year with some time on my hands and found the part of town with all the local tool shops. I bought a bunch of SDS bits for 2-4$ ea. 6mm -16mm they are metric but for my purposes drilling in concrete does not need to be that precise. I dont know why they are so much cheeper in HK as all of them were made in Europe (Denmark, Germany, France) I burned a bit out the other day and thought it was one of these but it was a hilti I had had for a while.
I would say get a 20 bits in various sizes and if they are crap then you only out $30 and you can give them to some one who would not put too much stress on them.
Cheers Jim

For that money how can you go wrong, I have a full set of Hilti cobalts and I don't think are much better then my noname commercial black oxide brand aircraft bits. Twist drill are like sawzall blades, they are crap after 3 uses...if anyone knows a good sharpening system let me know.
