Norton 78072700834 Abrasive Belt 120 Grit 3/4x18 in

Product Description

The NORTON 78072700834 is a coated abrasive belt designed for dry precision sanding and finishing applications. Built on a heavy-duty X-weight cloth backing with a closed-coat aluminum oxide abrasive, this belt delivers consistent stock removal and surface finishing at 120 grit (fine grade). The Series R228 construction uses a closed-coat density for even abrasive coverage, reducing loading on softer materials and maintaining cut rate across the belt's lifespan. At 0.75 inches wide and 18 inches long, it fits narrow belt sanders and file belt tools commonly used in metalworking, woodworking, and general fabrication environments.

This belt is suited for fine finishing passes on metal, wood, and composite materials in shop and field settings. The 120-grit fine grade makes it appropriate for surface prep before coating, deburring, or final smoothing after coarser stock removal. Machinists, fabricators, pipefitters, and general maintenance technicians typically reach for this belt size when working with file belt sanders, die grinders with belt attachments, or bench-mounted narrow belt units. Dry operation is required — this belt is not rated for wet sanding applications.

Key Features

• 120 grit fine grade for finish sanding and surface prep
• Aluminum oxide abrasive provides durable, consistent cut on metal and wood
• Closed-coat density minimizes loading and extends belt life
• X-weight cloth backing resists tearing under tension on narrow belt tools
• Dry-use construction suitable for shop and field environments
• Series R228 coated abrasive line for reliable performance across applications

Compatibility

Designed to fit narrow belt sanders and file belt tools accepting a 0.75-inch wide by 18-inch long abrasive belt. Verify platen and drive roller dimensions on the tool before installation.

Installation Notes

Power down and unplug the sander before changing belts. Confirm belt tracking direction — most belts have a recommended run direction indicated by an arrow on the inner surface. Seat the belt fully on the drive and idler rollers before tensioning, and test tracking at low speed before resuming work. Inspect the belt for tears or separation before each use.
