With a generous 2-inch cutting depth, this core bit is designed for precision drilling in thick concrete, brick, and cinder block—perfect for installing air conditioning lines, electrical conduit, vent pipes, and posts in basements or foundations.
This heavy-duty bit features a sintered diamond cutting edge bonded to a solid steel body, delivering professional-grade performance, clean cuts, and longer tool life. It’s engineered for universal compatibility with standard 3/8" shank drills—no special tools required.
