Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC installers drilling refrigerant line penetrations through cured structural concrete, this 1-1/4 inch Zz Turbo core bit handles hard aggregate mixes that wear down standard bits. The .125-inch segment height and turbo design provide faster cutting speeds while reducing heat buildup during extended drilling operations. The 5/8-11 threaded arbor fits standard angle grinders and handheld core drill rigs up to 2 horsepower. Diamond Vantage engineers this bit specifically for dense concrete applications where cutting speed and segment life matter. The turbo segment configuration moves slurry away from the cut face to maintain contact between diamonds and material. Built for mechanical contractors and concrete drillers running multiple penetrations per job in commercial and industrial settings.
