### ⭐⭐⭐⭐⭐ 10/10 holes.
*by M***N on February 3, 2026*

Deeeeez boys CUT. Look for the price, nothing is beating the quality. Sure go with a bigger brand name, but you could buy this set 3 times before you’d clear the value of a different brand.

### ⭐⭐⭐⭐ All great until….
*by C***Z on April 23, 2022*

The shipping was fast, as expected a nice and shiny set of hole makers. I put them to the test come the next work day. Sharp and durable (if used in the right way). All great until you find the tip of the smallest bit broke off. Not sure when and where but to my dismay one bit was no longer useable. I would recommend this set for light to medium light work.
