Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC installers boring through post-tensioned concrete in high-rise construction, this 8-inch turbo core bit handles the hardest aggregate mixes without stalling. The X301 Zz Turbo features a .165-inch wall thickness and 1 1/4-7 arbor connection for heavy-duty drilling equipment. Turbo segment design provides faster cutting speed and debris clearance in reinforced slabs up to 12 inches thick. The diamond matrix is formulated specifically for hard concrete applications where standard bits burn out or lose cutting efficiency. Wet drilling recommended for maximum segment life and core quality. This bit delivers consistent performance in dense structural concrete where you can't afford downtime from worn-out tooling. Built for concrete cutting contractors and mechanical trades running high-horsepower core rigs on commercial and industrial job sites.
