“Drill bit worked fantastic! Used it with a wet drill press with vacuum base. Drill 24 holes for my 2 car lifts I'm installing, and hardly any wear on the bit at all. Went through the 5500 lb cement and some 4x4 steel mesh, .120" diameter round steel in some spots, but still cut through pretty easy. Used lots of water. Price for the drill bit was reasonable, and shipping was very fast. I would recommend this drill bit and seller to anyone needing these drills. I bought the red upgraded bit.”
