    Note: Keep the diamond section of the drill bathed in the water while drilling. Start at a slight angle to get started, then tilt upright and use light pressure and a gentle rotation motion. “Let the diamonds do the work.” For longevity, use water, high speed, and gentle pressure. Overheating the tool will decrease tool lifespan and alter the tool shape.
