Diamond Core Drill Bit - Zenesis™ Series - Hard Concrete

Engineered for HVAC contractors drilling through post-tensioned concrete slabs in commercial buildings, this Zenesis™ Series core bit handles the demands of hard concrete applications. The 4-inch diameter with .155-inch segment thickness delivers consistent performance in dense, high-PSI concrete where standard bits fail. Diamond Vantage designed this bit with a 1 1/4-7 arbor connection for use with standard core drilling rigs. The segment design maintains cutting speed while managing heat buildup during extended drilling operations. Use wet to maximize bit life and maintain clean hole tolerances in structural concrete work. Built for mechanical contractors and concrete cutting professionals who drill penetrations in hardened concrete daily.
