Mark the location of holes that need to be drilled.

Use a template as a guide on the stone in order to avoid any mistakes during drilling process.

Clamp a piece of stone scrap under the stone being core drilled to prevent excessive chipping or “blowout” on the back side of the stone.

Proceed with drilling, pressing steadily until the dry core bit drills through the stone.
When drilling multiple holes, cool off the dry core bit by dipping it in cool water after each drilled hole.

Q: What materials can be core drilled using the Dry Core Bits?
A: The Dry Core Bits are designed to be used on granite, engineered stone and porcelain slab materials.

Q: What is the main advantage of using dry core bits over wet core bits?

A: We realized that many customers wanted to use wet core drills without water on the job site. When an installer has to makes an additional hole or two, they can not use water since the stone is already installed and using water will be difficult and costly due to the time consuming clean-up.
