Through trial and error, I found that these drill bits were simply not worth the risk... The bits would randomly stop spinning mid-use causing unnecessary delays and frustration. Not to mention, they seemed to wear down and become dull much quicker than other brands I have used in the past. The only positive aspect was the affordable price. Overall, i would not recommend these to any serious industrial and scientific workers..
