Concrete Core Drill Bit - Premium Black Precast Core Bore Bit

Designed for drilling anchor holes and utility penetrations through dense precast concrete panels, this core bit handles the hardest concrete applications. The black-coated diamond segments deliver consistent cutting performance in high-strength precast where standard bits wear out fast. Diamond Products engineers this bit to maintain cutting speed through rebar and aggregate without wandering or binding. The core bore design evacuates slurry efficiently to prevent segment glazing during deep cuts. Wet cutting required for proper diamond exposure and maximum segment life. Compatible with standard core drilling rigs and handheld systems. Built for concrete cutting contractors and industrial facility maintenance teams working with precast concrete structures, parking garages, and tilt-up construction.
