Norton 78072730030 Abrasive Belt 120 Grit Aluminum Oxide

Product Description

The NORTON 78072730030 is a coated abrasive belt designed for precision material removal and finishing on narrow-contact applications. Running at 120 grit, this fine-grade belt uses aluminum oxide abrasive bonded to a cloth backing with a closed coat density and X-weight backing for firm support under load. At 0.25 inches wide and 12 inches long, it fits compact file belt sanders and detail finishing tools used in metalworking, woodworking, and tool maintenance. The R228 series designation indicates a dry-operation belt intended for controlled, consistent stock removal on tight radii and contoured surfaces. Licensed trades and skilled shop technicians install and replace these belts during routine maintenance or when switching grit sequences.

This belt is suited for dry grinding, deburring, and fine finishing passes on metal, wood, and composite surfaces. Its narrow 0.25-inch width targets tight grooves, weld seams, inside contours, and small-diameter workpieces where wider belts cannot reach. The fine 120-grit rating makes it appropriate for final-stage material blending, light scale removal, and surface prep before coating or inspection. It is commonly used in maintenance shops, fabrication facilities, and field service applications where a compact file-belt tool is standard equipment.

Key Features

• 120 grit fine grade for controlled surface finishing and light stock removal
• Aluminum oxide abrasive provides consistent cut on metal and wood
• Closed coat density for uniform abrasive coverage across the full belt surface
• X-weight cloth backing delivers firm support and resistance to tearing under load
• Dry-operation rated for use on standard file belt and detail sanding tools
• Compact 0.25 inches x 12 inches size targets narrow grooves, radii, and contoured workpieces

Compatibility

Designed as an OEM-style replacement abrasive belt for compact file belt sanders and narrow-contact detail finishing tools that accept 0.25-inch wide by 12-inch long belts.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance technicians using standard file belt sander tooling. Power down and unplug the tool before changing belts. Verify belt tracking and tension according to the tool manufacturer guidelines before resuming operation. Inspect the platen or contact arm for wear that could cause uneven belt loading or premature failure.
