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

Designed for HVAC installers drilling vent holes through cinder block and poured walls, this wet-cutting diamond core bit handles brick, concrete, and masonry applications where clean penetrations matter. The diamond-segment design requires water feed during operation to control dust and extend cutting life. Virginia Abrasives engineers this bit for consistent performance in commercial and residential drilling work, from electrical conduit runs to plumbing chases. The wet-cutting method keeps the bit cool and prevents segment glazing that kills cheaper alternatives. Fits standard core drill rigs with appropriate arbor adapters. Built for mechanical contractors, masons, and plumbers running daily penetration work in structural materials.
