Marble Core Bits

Diamond core bits specifically designed for marble and other soft natural stone. Marble requires a softer bond and different segment geometry than granite or quartz to prevent cracking, chipping, and surface damage during drilling. These core bits are tuned for marble's unique hardness and density.

Whether you are drilling faucet holes in Carrara marble vanities or fixture openings in travertine surfaces, using the correct core bit prevents costly material damage. Our marble core bits produce clean, chip-free holes with smooth interior walls.

• Soft bond designed specifically for marble, travertine, and limestone
• Reduces chipping and cracking in delicate stone
• Available in common faucet and fixture hole sizes
• Use wet for best results and longest bit life
• Smooth hole finish requires less cleanup

Protect expensive marble slabs by using core bits made for softer natural stone.
