3M BELT3X181PK120 Sanding Belt 120 Grit 3x18 in 10 Pack

Product Description

The 3M COMPANY BELT3X181PK120 is a 120-grit power sanding belt engineered for rapid material removal on portable belt sanders. It measures 3 inches wide by 18 inches long and ships in a pack of 10 belts. Construction combines Cubitron abrasive grain with premium aluminum oxide blended minerals bonded to a heavy Y-weight cloth backing. A film splice design allows the belt to run in either direction, extending usable life and reducing the need to stop and reorient the tool during work.

This sanding belt is suited for finish preparation, stock removal, and surface leveling on wood, metal, and composite materials. The 120-grit rating places it in the fine-to-medium range, making it appropriate for final shaping passes and pre-finish smoothing. Portable belt sander users in residential construction, cabinet shops, metal fabrication, and general maintenance work are the primary installers of this consumable.

Installation Notes

Abrasive belts are installed by a user or technician after fully powering down and unplugging the sander. Confirm belt direction arrows align with tool rotation before securing the tension arm. Inspect the platen and drive rollers for debris or wear before mounting a new belt. Replace belts when cut rate slows noticeably or surface glazing is visible.
