Dry Core Bit - X301 Zz Turbo - Masonry

Designed for HVAC installers drilling through brick and block walls for refrigerant lines and condensate drains, this 5-inch dry core bit handles masonry applications without water cooling. The ZZ Turbo segment design provides faster cutting action in brick, concrete block, and similar masonry materials where wet drilling isn't practical. The .125-inch wall thickness balances durability with cutting speed, while the 5/8-11 threaded arbor fits standard angle grinders and core drill rigs. This dry-cutting bit works best on softer masonry materials and runs at lower speeds than wet bits to manage heat buildup. Built for mechanical contractors, masons, and electricians who need clean penetrations through masonry walls without the mess of water cooling systems.
