Core Drill Bit For Concrete - X302 Crown - General Purpose

Designed for HVAC installers drilling refrigerant line penetrations through basement walls and foundation slabs, this 1-1/2 inch diameter crown core bit handles general-purpose concrete drilling applications. The .125-inch wall thickness provides adequate durability for standard residential and light commercial work. Diamond segments cut through aggregate and rebar efficiently when paired with compatible core drill rigs. The 5/8-11 threaded arbor connection fits most standard hand-held and stand-mounted drilling equipment. This general-purpose crown design works in cured concrete, block, and masonry materials where precision holes are required for plumbing, electrical, and mechanical installations. Built for contractors and maintenance technicians running multiple holes per job in typical concrete conditions.
