DiamondCore Hole Drills - 3mm to 100mm

DiamondCore® Hole Drills can be used to make holes in bisque or high-fired ceramic, tile or glass. These hole drills allow you to create a hole after the final high-temp firing without having to calculate shrinkage. 

• Long lifespan if used properly with water
• Dust is controlled with water use
• Shaft size for normal household 3/8" cordless drill
• As the tool wears, a new layer of diamonds is exposed
• Much longer lasting than diamond edge hole drills

CAUTIONS:

• Use all safety precautions
• Always use safety goggles
• Always check to remove core after each drilling
• Make certain that debris does not get into moist clay
• Always use water to maximize tool life and control dust
• Use normal cordless drill and avoid getting water in drill
• Do not attempt to force or pry with this tool
• Keep out of the reach of children

Note: Keep the diamond section of the drill bathed in 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.
