3M 7010508242 Spiral Band 100 Grit 3/4 in Aluminum Oxide

Product Description

The 3M 7010508242 is a coated abrasive spiral band designed for use with spindle sanders and die grinders in material removal, blending, and finishing applications. The band measures 3/4 inches in diameter by 4 inches wide and runs at 100 grit, placing it in the fine grade range. The aluminum oxide abrasive is bonded to an X-weight cloth backing, which provides durability and resistance to tearing under load. This combination makes it well-suited for work on wood, composites, and light metals where consistent finish quality is required. Machinists, woodworkers, and fabricators are the typical end users for this type of spiral band.

This spiral band fits standard spindle sander drums and compatible rotary tool mandrels sized at 3/4 inches in diameter. At 100 grit fine grade, it is appropriate for finishing passes, light stock removal, and surface prep before sealing or coating. Typical applications include contour sanding on curved workpieces, edge finishing, and cleaning up inside curves or tight radii that flat abrasives cannot reach. It is sold individually with a minimum order quantity of 100 units.

Compatibility

Designed for use with spindle sander drums and rotary mandrels with a 3/4-inch diameter accepting standard spiral bands in a 4-inch width.

Installation Notes

Installation is performed by sliding the spiral band onto a matching sander drum or mandrel and securing it according to the tool manufacturer's instructions. Ensure the tool is fully powered down and unplugged before changing abrasive bands. Inspect the band for tears or separation before use and do not exceed the spindle speed rating specified by the tool manufacturer. Dispose of worn bands promptly to avoid inconsistent finish results.
