3M 7010512887 Spiral Band 100 Grit Fine 0.75x2 in

Product Description

The 3M 7010512887 is a coated abrasive spiral band designed for use with pneumatic and electric drum sanders in metalworking, woodworking, and finishing applications. Built on a heavy X-weight cloth backing with aluminum oxide abrasive, this band delivers consistent stock removal at 100 grit (Fine grade). The 0.75-inch diameter by 2-inch wide form factor fits standard expanding rubber drum mandrels. HVAC sheet metal fabricators, pipefitters, and general maintenance trades use spiral bands like this one for deburring, edge blending, and surface preparation on a variety of materials.

This spiral band is suited for inside diameter grinding and finishing on curved or contoured surfaces where flat abrasives cannot reach. The aluminum oxide grain is a general-purpose abrasive that performs on ferrous metals, non-ferrous metals, and hard woods. At 100 grit Fine grade, it is positioned for intermediate finishing passes — after coarser stock removal and before final polishing steps. Sold as a single band with a minimum order quantity of 100 units per order.

Key Features

• Aluminum oxide abrasive grain — versatile general-purpose cutting action on metal and wood
• 100 grit Fine grade — suited for intermediate finishing and surface blending
• Heavy X-weight cloth backing — resists tearing under load on drum sanders

Compatibility

Designed as an OEM-style replacement spiral band for use with standard 3/4-inch diameter expanding rubber drum mandrel sander setups common in metalworking and woodworking shops.

Installation Notes

Spiral bands are installed by a machinist, fabricator, or tradesperson onto an expanding rubber drum mandrel mounted in a drill press, bench grinder, or pneumatic die grinder. Power down and disconnect the tool before changing bands. Slide the band over the deflated or relaxed drum, then expand the mandrel to secure it before operating. Do not exceed the maximum RPM rating of the mandrel or tool arbor.
