According to my experience this Industrial and Scientific cutting tool failed to meet my expectations. The bit wears out quickly and the cut depth is inconsistent, causing issues with precision drilling..
Pros
The drill bit has a sturdy construction.
Cons
The durability and accuracy are lacking, leading to frequent replacements and wasted materials.
I use this in wood to get a good counter-recess for tons of screws. So far it has worked flawlessly. stays sharp after 100 holes in maple. Well finished, corner in place. very important.
