Rated 5 out of 5 by from Works great on stainless steel Went straight through stainless steel leaving a clean hole of the correct size.
Date published: 2023-07-09
Rated 1 out of 5 by from Not for heavy duty use I need 6 holes drilled and it was only able to drill one hole in pinch weld area on my truck without pre drilling. It was dull after just that first hole.
Date published: 2023-06-06
Rated 5 out of 5 by from Excellent bit It’s sharp - sharp enough that you could punch the hole size you need and begin to enlarge it without meaning to - I count that as a positive. It’s heavy and feels like it will hold up to real working conditions. It hasn’t lost its edge, I’ll revisit its value at that time.
Date published: 2023-01-27
Rated 5 out of 5 by from Is cost effective if you dont need a set of three. Works as advertised, and works on aluminum and wood.
Date published: 2022-12-21
Rated 5 out of 5 by from drill a starter hole first I liked the way this tool worked for me by following the instructions to the "T" I had no issues, it did the job well.
