• The cut out pattern comes from the actual sink turned upside down on the stone.

• This type of cut out has the stone overhanging the sink.

• A standard 3 1/2" hole saw is what I use to cut out the sink corners. A carbide hole saw is recommended.

• Cut the straight lines with your circular saw.

• Keep the stone supported while you complete the cut.

• Checking the rough cut.

• Now that the center is gone the finishing begins.

• Finishing the corners.

• A router and round over bit works well to finish the edges.

• Hand sand the finished edge with 100 grit paper.

• A large kitchen sink needs to be supported with a frame attached to the inside of the cabinet.

• Smaller bar type sinks can be fastened with silicone.

Call me with any questions. Better safe than sorry.
