Covington's magnetic-backed dot laps have nickel-plated diamond rings evenly spaced across the surface with small interruptions that allow for less loading of the disc.

Magnetic-backed diamond discs are super-fast to change and now available in five grit sizes: Extra Coarse-60g, Coarse-100g, Medium-260g, Fine-360g, and Extra Fine-600g. These discs have a 1" hole to center on the plate. Use in combination with Covington's 12" Horizontal Beveler/Grinder for optimum performance.
