Dry Core Bit - X301 Zz Turbo - Masonry

Description

Designed for HVAC installers drilling vent holes through brick and block walls, this 3-inch dry core bit handles masonry applications without water feed systems. The ZZ Turbo segment design clears dust faster than standard segments while maintaining cut speed in brick, concrete block, and stone. The .125-inch segment height provides extended life in abrasive materials. Fits angle grinders and rotary drills with standard 5/8-11 threaded arbors. Dry operation means no slurry mess and faster setup on residential and light commercial jobs. Cuts clean holes for electrical conduit, plumbing penetrations, and mechanical system installations. Built for masons, electricians, and mechanical contractors working in masonry structures where water drilling isn't practical.
