Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Engineered for HVAC installers boring through cured structural concrete in commercial buildings, this 5-1/2 inch Zz Turbo core bit handles the hardest concrete mixes without hesitation. The .155-inch segment height with 1 1/4-7 thread arbor connection delivers consistent performance in high-compression applications where standard bits wear out fast. Diamond Vantage builds this bit with turbo segments that clear dust efficiently while maintaining cutting speed through rebar and aggregate. The X301 series uses a specialized bond matrix formulated to resist heat buildup during extended drilling operations. Fits standard core drill rigs with compatible arbor threading. Built for drilling contractors and mechanical trades running production work in dense concrete.
