Wet Core Bits

Wet diamond core bits for drilling precise holes in granite, marble, quartz, and engineered stone. Wet core bits are the shop standard for fabrication, delivering clean holes with minimal chipping when used with a water-fed core drill or drill press. Water cools the bit, flushes debris, and extends diamond life significantly.

Our wet core bits are available in all common diameters for faucet holes, soap dispensers, cooktop cutouts, and other fixture openings. They feature sintered diamond segments for long-lasting performance on hard natural and engineered stone.

• Sintered diamond segments for extended bit life
• Available in standard faucet and fixture hole sizes
• Requires water feed for cooling and debris removal
• Clean, chip-free holes in granite, marble, quartz, and porcelain
• Fits standard drill presses and core drill motors

Choose wet core bits for high-volume shop drilling where quality and tool life matter most.
