3M 7100204457 Cloth Roll 39x25yd 80 Grit Silicon Carbide

Product Description

The 3M 7100204457 is a silicon carbide abrasive cloth roll designed for heavy-duty sanding and finishing applications. Built on a durable screen cloth backing, this roll measures 39 inches wide by 25 yards long and carries an 80-grit abrasive grade. The open-mesh screen construction allows dust and debris to pass through during use, reducing loading and extending the working life of the roll. It is rated for both wet and dry operation, giving technicians and finishing professionals flexibility across a range of surface preparation tasks. Metal fabricators, woodworkers, and industrial finishing crews are the typical end users.

This cloth roll suits applications where consistent stock removal and surface preparation are required across wide workpieces. The 39-inch width makes it well matched to wide-belt sanding machines and similar industrial equipment. The 80-grit rating positions it for medium material removal, such as smoothing rough surfaces, removing scale or rust, or preparing a substrate before finer finishing passes. Both wet and dry process environments are supported by the screen cloth construction.
