Concrete Core Drill Bit - X301 Zz Turbo - Hard Concrete

Designed for HVAC installers boring through post-tensioned concrete for refrigerant lines and conduit runs. This 3-inch diameter turbo core bit features a .155 wall thickness and 1 1/4-7 thread arbor connection, engineered specifically for hard concrete applications where standard bits bog down or fracture. The Zz Turbo segment configuration provides faster cutting speeds and improved debris removal in dense aggregate mixes. Diamond Vantage manufactures this bit with industrial-grade diamond segments that maintain cutting performance through rebar and wire mesh without chipping. Wet or dry drilling capability makes it adaptable to jobsite conditions where water access varies. Built for mechanical contractors and concrete cutting specialists who need reliable penetration in hardened structural concrete.
