These oversized discs have wave-like edges that curl over the sides of a sanding pad, a design that helps prevent the edge of the disc from digging into the surface of the wood, particularly when working a tight radius. The stearate coating on the aluminum oxide grit discs helps prevent clogging and extends the life of the paper.
The paper is flexible C weight and has a loop backing. The discs fit 2” or 3”sanding pads.
These are excellent-quality sanding discs.
Made in the USA.
