Diamond Core Drill Bit - Wet Cutting - Premium - Brick, Concrete, Masonry

Designed for plumbers and electricians drilling clean holes through brick walls and concrete block for conduit and pipe runs, this wet-cutting diamond core bit handles residential and light commercial masonry work. The diamond-embedded segments cut through brick, concrete, and CMU while water cooling extends bit life and controls dust on interior jobs. Wet cutting keeps the diamond matrix from overheating during extended drilling sessions, letting you work through multiple penetrations without stopping to cool down. The core design removes material efficiently, reducing binding and letting you pull plugs cleanly from finished walls. Built for trade contractors who need reliable performance drilling utility penetrations and mechanical openings in masonry construction.
