Pro-Tip: To achieve the smoothest possible edge on marble or slate, perform a "climb cut" (moving the grinder in the direction of the blade rotation) for your final pass. Using this technique with the DB442C's turbo rim will help keep the diamonds engaged in the material more effectively, resulting in a factory-clean edge with zero micro-chipping.
