3M 7100030244 Spiral Band 120 Grit Fine 1.5x1.5 in

Product Description

The 3M 7100030244 is a coated abrasive spiral band designed for use with drum sanders and spindle sanding applications in metalworking, woodworking, and general fabrication. Built with aluminum oxide abrasive on an X-weight cloth backing, this band delivers consistent material removal at a fine 120 grit rating. The X-weight cloth backing provides durability under load, resisting tearing and deformation during extended use. Rated to a maximum of 10,000 RPM, it is suited for both bench-mounted and portable spindle sanding setups. Each unit measures 1.5 inches in diameter by 1.5 inches wide.

This spiral band is used in light deburring, surface blending, contour sanding, and finish preparation on metal, wood, and composite materials. The fine 120 grit rating makes it appropriate for final shaping passes and pre-finish smoothing where a controlled scratch pattern is needed. Machinists, fabricators, woodworkers, and maintenance technicians typically install and use this abrasive in production and repair environments.
