Core Bits / Thin Wall Core Bits

Thin wall core bits are a sub-category of our core bit selection, designed for drilling clean holes in stone with minimal material removal. The thin-wall design reduces friction and heat buildup, extending bit life when drilling through granite, marble, quartz, and quartzite. These bits are used for faucet holes, soap dispenser openings, and other countertop penetrations.
