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

Designed for HVAC installers boring refrigerant line passages through brick veneer and block walls, this wet-cutting diamond core bit handles masonry drilling applications where clean holes matter. The diamond-embedded segments cut through concrete, brick, and block without wandering or chipping edges when used with water feed. Wet cutting keeps the bit cool and extends diamond life while clearing dust from the cut. The arbor fits standard rotary drills and core rigs used on residential and light commercial jobs. Use with continuous water flow to prevent segment damage and maintain cutting speed through dense materials. Built for mechanical contractors, masons, and general contractors running penetrations through structural masonry.
