This 3 inch core drill bit is one of the best general purpose bits made.
We cut many 3" cores every year. In the picture shown you will see that this 3" core bit can cut through the heaviest rebar and has thick 10mm Teeth. The darker, reddish appearing smudges in the core is #10 rebar that our core drill bits reguraly cut strait through. Our bit will devour reinforced concrete with any size rebar in the path.
Average close to 60 holes drilled with this core drill bit with medium to lite weight concrete and over 100 holes or more through brick or block structures.
