Core Bit Drill - Premium Black Large Diameter Wet Core Bits - Solid Back

Designed for plumbing and HVAC contractors boring large-diameter holes through structural concrete and masonry walls. These wet core bits feature a solid back construction that provides stability during deep cuts and reduces bit wobble on heavy-duty drilling applications. The black diamond segment configuration delivers consistent cutting performance in reinforced concrete, cured slabs, and block work. Water-fed design keeps the bit cool and clears debris from the cut for faster penetration and extended segment life. Large diameter sizing handles the demanding bore requirements for commercial pipe chases, electrical conduit runs, and mechanical system installations. Built for concrete cutting professionals and specialty drilling contractors running high-horsepower core rigs on job sites requiring clean, accurate large-format holes.
