Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC installers boring through post-tensioned slabs and structural concrete in commercial builds. The X301 Zz Turbo handles hard aggregate mixes that burn through standard bits. This 4-inch diameter core bit features a .155-inch segment height and 1 1/4-7 thread arbor connection for compatibility with most handheld and rig-mounted core drills. Turbo segment design clears slurry faster and runs cooler during extended cuts. Diamond Vantage engineers this bit specifically for hard concrete applications where standard matrix formulations fail. Segments are laser-welded to prevent loss during high-torque operation. Works wet or dry depending on job site conditions. Built for mechanical contractors, plumbers, and electricians running penetrations through cured structural concrete where clean holes and bit longevity matter.
