The bit did not cut the hole as fast as I expected. The slow rate was beneficial. The drilled hole was perfectly smooth and straight. Made the installation of anchors with ease.

it was BENT right out of the package - had to go back to return the thing & then the store was out of stock - I could have drilled the hole with my pocketknife by the time I got done running around to find what I needed! How, in todays world of manufacturing Quality-Control, does a bent drill bit even make it thru the hardening-process, let alone to the store-shelf?!?

I purchased these bits to replace a set from another manufacturer. The other bits wouldn’t drill through 3” concrete ( without rebar). These bits went through with easy. I only drilled 9 holes, but you can’t even tell that the bits were used. They are still sharp ! No signs of wear at all! Definitely would recommend these bits. Would buy again, if needed!

Cutting tip on the end falls off after about 2-3 holes. Very poor product
