This small Diamond Hole Drill Set is available for a limited time. It comes with 6mm and 15mm diameter hole drills. These diamond hole drills are perfect for drilling holes in bisque or high-fired ceramic, tile, or glass.
*Technique Note: Keep the diamond section of the drill bathed in water while drilling. Use an ordinary cordless drill. Start at a slight angle to get started, then tilt upright and use light pressure, high speed and a gentle rotation motion.... "Letting the diamonds do the work." For longevity use water, high speed an gentle pressure. Overheating the tool will greatly decrease tool lifespan and change the tool shape.
