Premium Core Bit

Mr. Stone Core Bits are the preferred Diamond Tools used by fabricators to drill into any stone. These thin walled segmented Core Bits are sintered and crowned at the bottom for better drilling and hollow on the inside so water can easily flow into the core barrel for quick cooling. They work extremely well for drilling holes into granite.

These core bits are designed to drill clean, smooth holes such as faucet mounting holes in counter tops. They can also be adapted for use in the construction trades wherever holes may be needed for water, gas and electric piping, especially when natural stone is already installed.

These premium core bits are best used for wet drilling, as it will increase the lifespan of the core bit. However these core bits can also be used in a dry application, with the same speed and precision.
