9X11IN 320A TRI-M-ITE FRECUT 426U (25)

Dry sanding only by hand or machine.
A specially treated paper with sharp silicon carbide mineral that cuts especially fast, and resists loading when working on wood, plastic or fiberglass.
Ideal for sanding between coats of paint, varnish, or other finishes.

While it cuts faster, the silicon carbide abrasive is not as durable as aluminum oxide abrasives; this is less of an issue with hand sanding compared to machine sanding.
