Norton 78072721875 Abrasive Belt 100 Grit 3x132 in

Product Description

The NORTON 78072721875 is a coated abrasive belt designed for dry grinding, blending, and finishing operations on metal, wood, and composite surfaces. It runs at 3 inches wide by 132 inches long and cuts at 100 grit, placing it in the fine grade range. The belt uses aluminum oxide abrasive grain on a closed-coat pattern over a heavyweight X-weight cloth backing, which resists tearing under load and flexes consistently around contact wheels and platens. It belongs to the NORTON R228 series. This type of belt is a standard consumable stocked and replaced by machinists, fabricators, and maintenance technicians running wide-belt or edge-belt sanders and grinders.

This belt is suited for dry-only operation on stationary or portable belt sanding equipment that accepts a 3-inch by 132-inch belt. The 100-grit fine grade makes it appropriate for intermediate to finish-stage material removal, surface preparation before coating, weld blending, and deburring on ferrous and non-ferrous metals as well as hardwoods. The closed-coat construction delivers consistent scratch patterns and uniform finish quality across the workpiece. Industrial maintenance shops, metal fabrication facilities, and woodworking operations are typical end-use environments.

Installation Notes

Belt installation and replacement is typically performed by a machinist, fabricator, or maintenance technician. Power down and lockout the machine before removing the spent belt and fitting the new one. Confirm belt tracking adjustment after installation and run briefly at low load before full-speed operation. Inspect the splice joint for alignment — a misaligned splice can cause vibration or premature belt failure.
