The D5 DiamondCore Rotary Tool has a cylinder tip that comes in a coarse 80 grit size that makes it perfect for grinding pottery pieces. When used properly, this tool has a long lifespan. As you use this diamond rotary tool, a new layer of diamonds is exposed as it wears down.
*Technique Note: For longevity use water, high speed and gentle pressure. "Let the Diamonds do the work" and overheating the tool will greatly decrease tool lifespan and change the tool shape.
