1"-6" Inch Diamond Wet Core Drill Bit Set 1-1/4” Threaded by BLUEROCK Tools for Concrete Rebar Asphalt Brick Rock Masonry Hole Barrel Coring Bits

I would buy again

The drill bits worked ok on straight concrete but when we used them where there was rebar the bit didn't last long. Bits are for concrete only. I did know this when I bought them. The drill is awesome and the bits are ok as long as you don't hit rebar.

These bits are a little thin,but do there job. Have drilled 6 5'' holes and a few 3'' at 8'' depths with water and they work fine.
