3M 7010508249 Spiral Band 120 Grit Fine Grade 3/4 X 1/2 in

Product Description

The 3M 7010508249 is a coated abrasive spiral band designed for use with rotary sanding drums in deburring, blending, and surface finishing applications. Built on a cloth backing rated at X weight for durability under load, it uses aluminum oxide grain at 120 grit for consistent material removal at a fine grade. The 3/4 inch diameter and 1/2 inch wide profile fits standard spiral-band mandrels used in die grinders and bench-mounted drum sanders. Machinists, fabricators, and finishing tradespeople install these bands when working on metal, wood, or composite surfaces that require controlled stock removal without aggressive surface damage.

This spiral band suits light to medium finishing work in shop and field environments. Typical applications include inside-diameter smoothing on curved cuts, weld bead blending, edge finishing on sheet metal, and surface prep before coating or painting. The fine 120 grit makes it well suited to final-pass work where surface finish quality matters more than rapid stock removal. It is sold individually with a minimum order quantity of 100 units, making it appropriate for shops that cycle through abrasive consumables at regular volume.

Key Features

• Aluminum oxide abrasive material delivers consistent cut rate on metal, wood, and composites
• 120 grit fine grade for controlled surface finishing and final-pass blending
• X-weight cloth backing resists tearing and heat buildup under rotary load
• 3/4 inch diameter fits standard spiral-band mandrels for die grinders and drum sanders
• 1/2 inch wide profile for precise access in tight contours and inside-diameter work

Compatibility

Designed for use with spiral-band sanding mandrels accepting a 3/4 inch diameter band. Verify mandrel width accepts a 1/2 inch wide band before installation.

Installation Notes

Installation is performed by machinists or finishing tradespeople using standard rotary tools. Power down and disconnect the tool from its power source before mounting or removing the band. Seat the band fully onto the mandrel and confirm it is secure before operating at speed. Do not exceed the maximum RPM rating of the mandrel or the tool.
