Review: Great bits - wonderful quality - The drill bits are hard to beat. For the price, they drill well, keep their edge, and when dull, they can sharpen multiple times. Even if other bits of higher quality were sought, chances are you will break the bit before you get the life out of it. These, I can easily purchase again and again for a small fraction of the cost. I've had no issues with them at all. The length is great. True to size. Straight. packaged well. Great value. Durable, and they cut metal. That is what is most important to me. I love it and all the varying sizes.
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!

### ⭐⭐⭐⭐⭐ Worth buying for installing rivnuts
*by M***Y on December 24, 2025*

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.
