Cryogenic drills

Chances are, they are slightly better than drill bits the average diy type person gets free with a power devil 6v cordless drill...so when they arrive, and put to use, they think they are the best thing since sliced bread.....Usual story probably, burn one out, and they will send you a new one, free, if you pay the return postage of £8.95.

Perhaps, its like bread that has been frozen and defrosted, average loaf to start with, freeze it, then defrost it, and its much tougher than it ever was before freezing.

tbh, with the amount of cheap chinese drill bits I've seen recently which have the cutting edge clearance ground the wrong way, you could probably sell sharpened spoons as the next big thing and people would find 'em better...
