Core Bits For Concrete - X300 - Concrete

Designed for HVAC installers drilling refrigerant line penetrations through poured concrete walls and floors, this X300 series core bit delivers consistent performance in standard concrete applications. The 1-inch diameter with .125-inch wall thickness provides the rigidity needed for accurate holes while the 1 1/4-7 thread connection fits most standard core drilling rigs. Diamond Vantage engineers this bit with a segmented design that clears concrete dust efficiently during wet drilling operations. The narrow kerf reduces drilling resistance and extends bit life across multiple jobs. Suitable for mechanical contractors running conduit and piping through structural concrete, as well as electrical crews installing anchor systems in commercial construction. Built for trade professionals who need reliable core drilling performance without excessive tool costs.
