I was able to drill 4 holes through stone and the 8 inch cement block the stone was on. Drilled holes with my Dewalt 1/2 inch hammer drill. Best cement drill bit I ever used.

Drills quickly through poured concrete walls. Still sharp after multiple drillings. Much better than competing products.

Bought this bit to drill through brick and concrete block so I could install another frost free hose bib for the back yard. Went through the brick easily and concrete block like it wasn't even there. Good quality carbide and the bit itself should serve well for many more holes.

This is an absolute beast of a bit. They say its only for concrete and block however they will drill almost anything...wont do concrete with rebar or thick metal

Used this to drill vent holes through a cement block barbecue with cells filled with concrete and large stone. Worked very well with a Makita 1/2" 18v Hammer Drill, and it made the job relatively easy.

I had purchased a number of less expensive bits over the years. None last as long as this Diablo bit. The most common size I use is 5/32 to drill pilot holes for self tapping concrete screws. I used this larger one to make holes for pipe in concrete and block walls. It works well in the Dewalt Atomic 20V cordless hammer drill. Thru cinder block like butter. I can't count how many holes we drilled in the last three days. Perhaps 30. Most thru air but some all block for the full 8 inches. One thing I really like is the durability. The last hole is as good as the first. It doesn't seem to dull at all. Other bits we had would dull and break out the block on the exit side. So far this one has not. Happy user.
