I needed an exploratory pilot hole through a concrete block wall before I drilled a 2 ½ inch hole for a mini split air conditioner installation. Worked quickly and easily.

Not matching my expectation

Easily drilled through a few thick concrete block walls with this. No sign of wear. Was worried about it snapping or bending given the length (and that it's only 1/4" thick). Worries apparently unfounded!

I was surprised to find this drill bit on Amazon at such a great price & shipped right to my door! So far it has held up on many jobs ( sand molds) and still is just as sharp as new!

Well made! The bit went thru drywall, cinder blocks and stucco as if it was not there! I will make sure to buy more from this company in the future

Used for cutting through 70 year old concrete. Was a fight but it did the job. Working on other 3000lb slabs are not an issue either

Us security wiring guys need an even longer bit for going up through windows through multiple layers of block sometimes. This one sometimes is like 6 or 12 inches too short. My boss bought one longer than this so I know they exist but you have to do some digging to find them.This bit does the job well - you'll have to pump the drill bit back and forth a bit to clean out your holes as you go a little more than with the non rebar bits, but it holds in the hole way better. Just looks and feels like a solid drill bit. Just wish I could get them even longer.

I used this bit along with a Hilti hammer drill and it went through my house foundation containing rebar with ease. I tried using a regular Carbide bit and it got stuck when I hit rebar. This Diablo bit went through the revaf and concrete with no problems.
