3M 7010508220 Spiral Sanding Band 100 Grit 3/4 X 3/4 Inch

Product Description

The 3M 7010508220 is a coated abrasive spiral band designed for cylindrical and contour sanding in portable and stationary drum sanding applications. It uses aluminum oxide as the abrasive material, a mineral well suited for sanding ferrous metals, hardwoods, and composites. The band measures 3/4 inches in diameter and 3/4 inches wide, fits standard drum mandrels of the same size, and runs at 100 grit, placing it in the fine grade range. The cloth backing is rated X-weight, which provides durability and resistance to tearing during aggressive material removal passes. Machinists, fabricators, and woodworkers typically install and use this band in production or maintenance settings.

This spiral band is suited for fine finishing work on curved surfaces, inside bores, and contoured profiles where flat abrasives cannot reach. The 3/4 inch diameter and 3/4 inch width make it a direct fit for small drum sander mandrels used on drill presses, spindle sanders, and handheld rotary tools configured with the appropriate drum. It is commonly used on wood, metal, and similar materials when a smooth, refined surface is required after coarser stock removal steps.

Key Features

• Aluminum oxide abrasive material — durable and consistent cut on wood and metal
• 100 grit fine grade — suited for finishing passes and surface refinement
• 3/4 inch diameter x 3/4 inch wide — fits standard small drum mandrels
• X-weight cloth backing — resists tearing under load during sanding operations
• Coated abrasive construction — uniform grit distribution across the band surface

Compatibility

Designed as a standard replacement spiral sanding band for drum mandrels sized at 3/4 inch diameter. Confirm mandrel size and arbor compatibility before installation.

Installation Notes

Spiral bands are installed by stretching the band over a rubber drum mandrel of the matching diameter, then expanding the mandrel to secure the band in place. Ensure the rotary tool, drill press, or spindle sander is powered off and unplugged before changing bands. Do not exceed the maximum RPM rating of the mandrel or the sanding tool. Inspect the band for tears or glazing before use and replace if the abrasive surface shows significant wear.
