Review: Great bits - These bits are working great for me...still using first one and have poked at least 70 holes in thinner stainless in a shipping container. I just poked another 10 holes today and quick easy mounting wire hold downs to dress up the runs. First one not broke and still sharp...not as easy as first hole but still respectable and prob by 100 holes will get to my bit sharpener to prolong the life of the bit and not break by pushing too hard. Great value in my opinion for my needs!
Review: Worth buying for installing rivnuts - Bought these for a job and I will be buying more! Cuts down on the time I spend drilling with other drill bits. Good quality. Stays sharp when using cutting oil but they will get ate up if you use them hard. Nice storage case and function as designed.

### ⭐⭐⭐⭐⭐ Great bits!
*by S***L on February 1, 2026*

These work great. They seem to last well enough for a small drillbit. We're drilling 18g steel and as long as we're careful we can easily get 100+ holes per bit.
