There was a problem filtering reviews right now. Please try again later.
I have used them on both steel and aluminum with good results. They leave a smooth finish that requires no additional “clean up” and none of the pieces shows any wear so far.
I did not rate longevity and durability solely because I haven’t had the set long enough. That said the total lack of wear exhibited by the bits so far strongly suggests to me that durability and longevity are unlikely to be an issue. And, to be honest, given that they perform so well, at this price I’m really not concerned about longevity. (As long as they’re still available if I need to replace them of course!!!)
P.S. No inducement received for this review.
I'm an idiot and used the wrong one to countersink the holes for my standard M3 screws (there's 2 for M3), so that's my fault. However, it got the job done with my Ryobi hand drill as you can see in the pictures.
While it did get the job done it did come out a little ugly. However, that could be due to the fact that I used a hand drill instead of something like a drill press. I didn't need it to be fancy, just functional, and for that it worked. I also used some 3 in 1 oil. Wasn't sure if I was supposed to or not, but I've seen other metal shops use oil so I figured why not. The bits went through the aluminum like butter.
Can you tell I'm not a metal worker?

Used in a milling machine/tail stick on a lathe - ultimate conditions, still chattery.
