CNC Tools / CNC Consumables / Blind Hole Bits

CNC blind hole bits are flat-bottom drilling tools designed for use on CNC stone fabrication machines. These bits create precise, depth-controlled holes for undermount sink clips, faucet installations, and hardware mounting in granite, marble, quartz, and quartzite slabs. Part of our CNC Consumables line, they are built for automated, high-volume production.
