Product Description

The Norton NorZon Plus R821 durable, large-diameter, cotton-backed discs are suitable for dimensioning and finishing metals and wood. These discs have no center hole for full-face usage. Pressure sensitive adhesive sticks when pressure is applied, without messing with solvents, water, or heat.

Coated abrasives have individual abrasive grains are spaced at a predetermined distance from one another. This is a closed-coat disc. A closed-coat covers 100 percent of the surface with abrasive grains, for more stiffness and better surface finish than an equivalent open coat, where abrasive grit covers 50 to 70 percent of the surface. The cloth backing is stiffer, tougher, and thicker than a paper or film backing. Cloth resists tearing while bending and flexing during use. This disc is suitable for use with a die grinder. Use with molded-rubber back up pads. Use a hard pad for aggressive cutting, a medium pad for general-purpose applications, or a soft pad for contours and fine finishing work.

Zirconia alumina is a self-sharpening abrasive that allows for a faster cut rate and longer life than aluminum oxide, due to its ability to fracture and refracture, creating new cutting edges. Zirconia alumina is often used for high stock removal on wood and metals.
