The Red Heatless Wheels have a ceramic-coated abrasive grain that ensures a smooth, free, cutting wheel at the coolest temperatures. This is due to the unusual micro-chipping action of the crystals as they wear. The wheels are made of non-contaminating pure alpha aluminum oxide hexagonal crystals with a tough ceramic coating. Great for use on all non-precious and semi-precious metals, porcelains, cercons and lava – there’s no need to change back to a silicon carbide wheel. The wheels are long lasting and exhibits excellent uniform wear and available in the most popular Mizzy sizes.
