Dry Core Bit - X301 Zz Turbo - Masonry

Designed for HVAC installers drilling small-diameter holes through brick and block walls for refrigerant lines and electrical conduits. This 1-inch dry core bit features ZZ Turbo segmented design that cuts clean through masonry without water, keeping job sites dry and reducing setup time. The .110-inch segment height and 5/8-11 thread attachment fits standard angle grinders and small core rigs. Turbo segments provide faster material removal in brick, CMU, and soft concrete compared to continuous rim bits. The compact diameter makes it suitable for precise penetrations where larger bits won't fit. Built for mechanical contractors, electricians, and maintenance technicians who need quick, clean holes in masonry without wet cutting equipment.
