Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC and electrical contractors drilling large-diameter penetrations through heavily reinforced commercial foundations and structural walls. The X301 Zz Turbo features aggressive diamond segment geometry engineered specifically for hard concrete applications where standard bits bog down or wear out fast. This 11-inch diameter bit with .187-inch segment height and 1 1/4-7 thread connection delivers consistent cutting speed in aggregate-dense mixes and high-PSI pours. The turbo segment design improves debris removal and cooling during deep cuts, extending bit life on demanding jobsites. Fits standard core drilling rigs with 1 1/4-7 arbor connections. Built for drilling contractors and mechanical trades running multiple holes daily in hard concrete structures.
