Core Drill Bit For Concrete - X302 Crown - General Purpose

Designed for HVAC installers drilling refrigerant line penetrations through poured concrete walls and floors, this 3/4-inch crown core bit handles general-purpose coring in residential and commercial applications. The .125-inch wall thickness provides the durability needed for multiple holes in medium-strength concrete without excessive wear. Standard 5/8-11 thread mount fits most handheld core drill rigs used on job sites. The crown design delivers clean entry and exit points while maintaining straight bore alignment through slabs up to 8 inches thick. Wet or dry operation capability means you can work in occupied spaces where water containment is difficult. Built for electricians, plumbers, and mechanical contractors who need reliable small-diameter penetrations without calling in specialty drilling crews.
