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.

Q: What materials can be core drilled using the Dry Core Bits?

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.
