Dry Core Bit - X301 Zz Turbo - Masonry

Description

Designed for HVAC installers boring through brick and block walls for refrigerant line sets, this 2-1/4 inch dry core bit handles masonry drilling without water hookup. The ZZ Turbo segment design clears dust efficiently while the .125-inch wall thickness provides stability during penetration work. The 5/8-11 threaded arbor fits standard angle grinders and core drill rigs for quick bit changes on the job. Dry operation means faster setup on interior walls where water containment creates problems. This Diamond Vantage bit cuts clean holes through CMU, brick veneer, and concrete block without the mess of wet drilling systems. Built for electricians, plumbers, and mechanical contractors running conduit and piping through masonry structures.
