Heavy duty, quality. Seems like it will last a really long time. Whenever our shop has drill bits and we are unsure of wire gauge size, we just use this. Great price.

I can’t imagine working with drills and bolts without the guidance of this well made and easily read tool

I inherited a dozen #30 drill bits when I bought a home built airplane. None of them would go in the #30 hole, yet when I put them in the #29 hole they flopped around. Might the #30 hole have been a bit undersized?

This product is very precise, very high quality drilled holes, however the printing of the numbers and labels were a bit blurred which I didnt like. It would be nicer if they were laser etched or printed finer. The tool is overall great quality, very strong steel, and will last a life time and more if its taken care of. This will be the only 1 I ever need to buy.
