Review on Industrial Masonry Drill Bits Set: Optimize Your Search by Joshua Garris

Bought because I ran out of masonry drills. They're advertised as heavy duty, but the first time I used the first bit, the 1/2" bit broke halfway through the grout between the bricks, leaving metal spikes in the hole I need to gouge. They are NOT intended to be used with a hammer drill, only with a regular drill, so be sure not to turn on the hammer function, they probably won't last a second on the hammer. I contacted the seller to share my experience and they made it right for me so I can't really blame them. I would only use this type of drill. for easier work, in other materials. I'll get regular masonry bits for more holes in concrete or brick.
