Blind Hole Bits

Blind hole bits are designed for drilling flat-bottomed holes in stone slabs. These bits are commonly used when fabricating undermount sink cutouts, faucet holes, and other stone openings that require a precise depth stop. Suitable for granite, marble, quartz, and quartzite, they deliver clean holes without breaking through the slab.

• Flat-bottom drilling for controlled hole depth
• Used for sink cutouts, faucet holes, and hardware mounting
• Compatible with CNC machines and drill presses
