3M 7010512862 Spiral Band 80 Grit Aluminum Oxide

Product Description

The 3M 7010512862 is a coated abrasive spiral band designed for use with rotary drum sander mandrels in deburring, blending, and finishing applications. Built with aluminum oxide abrasive on a heavy X-weight cloth backing, this band delivers consistent cut and durability across metal, wood, and composite surfaces. At 80 grit, it falls in the medium grade range — aggressive enough to remove burrs and shape edges while leaving a surface ready for finer finishing passes. The cloth backing resists tearing under the flex and heat generated by rotary tooling. Machinists, metal fabricators, and finishing professionals reach for this band when working inside bores, contoured edges, and tight radii where flat abrasives cannot reach.

This spiral band is suited for use on bench-mounted and handheld rotary tools in production and job-shop environments. Typical applications include deburring drilled holes, blending weld seams, and finishing the interior surfaces of tubing or cast parts. The 3/8 inch diameter and 1/2 inch width make it a standard fit for small-diameter drum mandrels commonly used in metal fabrication, woodworking shops, and HVAC sheet metal work. It is sold individually per package, with a minimum order quantity of 100 units.

Key Features

• 80 grit medium grade aluminum oxide abrasive for aggressive material removal with controlled finish
• Heavy X-weight cloth backing resists tearing and conforms to curved or contoured workpiece surfaces
• 3/8 inch diameter fits standard small-drum mandrels for rotary tools and drill-press sanding attachments
• 1/2 inch band width provides adequate contact area for deburring and edge blending in tight spaces
• Coated abrasive construction delivers consistent grit density across the full working surface

Compatibility

Designed as an OEM-style replacement or production consumable for use with 3/8 inch rotary drum sander mandrels on standard rotary tools, drill presses, and bench-mounted sanding stations.

Installation Notes

Spiral bands are installed by stretching the band over a rubber drum mandrel sized to match the band diameter. Ensure the rotary tool or drill press is powered off and unplugged before mounting or removing bands. Do not exceed the maximum RPM rating of the mandrel being used. Inspect the band for tears or separation before each use and replace immediately if backing damage is observed.
