Norton 78072718700 Abrasive Belt 50 Grit 0.5x12 in

Product Description

The NORTON 78072718700 is a coated abrasive belt designed for aggressive material removal on metal, wood, and composite surfaces. Built on a heavyweight Y-weight polyester backing, this belt handles the mechanical stress of high-pressure grinding and finishing applications without backing failure. The ceramic alumina abrasive grain is self-sharpening, which maintains cut rate over the life of the belt and reduces the frequency of belt changes on production lines and job sites. At 50 grit, this is a coarse-grade belt suited for stock removal, weld blending, and surface preparation rather than finishing passes. It runs in both wet and dry operating conditions.

This belt is used on 1/2-inch-wide belt sanders and inline grinders common in metal fabrication shops, HVAC duct work, plumbing rough-in, and general trade applications where tight clearances require a narrow belt. The 12-inch length fits compact portable belt sanders and stationary contact-wheel machines configured for that belt size. Closed-coat construction maximizes abrasive coverage on the backing, which improves cut aggressiveness on hard metals and dense materials. The R983 series designation identifies the product line within the NORTON coated abrasive family.

Key Features

• Ceramic alumina grain self-sharpens during use for sustained stock removal
• Y-weight polyester backing resists tearing under high contact pressure
• Closed-coat construction maximizes abrasive density across the belt surface
• Rated for both wet and dry operation
• 50 grit coarse grade optimized for stock removal and weld blending
• Series R983 for consistent reorder and replacement matching

Compatibility

Designed for use on 1/2-inch by 12-inch belt sanders and contact-wheel grinders configured for this belt size. Verify the drive and idler wheel dimensions of the specific machine before installation.

Installation Notes

Belt installation should be performed with the machine unplugged or the circuit de-energized at the disconnect. Confirm belt tracking adjustment before running under load. Inspect the contact wheel and platen for wear or damage that could cause uneven belt loading or premature failure. Replace belts before backing frays to avoid workpiece damage and operator hazard.
