Dynabrade 79012 Abrasive Belt 80 Grit 1/2x12 in Zirconia

Product Description

The DYNABRADE 79012 is a coated abrasive belt designed for use with narrow belt file sanders and die grinders that accept 1/2 x 12 inch belts. It runs on a zirconia alumina abrasive grain bonded to a Y-weight polyester cloth backing, which delivers consistent cut rate and resistance to heat and loading during aggressive stock removal passes. At 80 grit, this belt falls in the medium grade range, making it well suited for blending welds, deburring edges, and shaping metal or composite surfaces where a balance of cut speed and surface finish is required. Licensed trades and fabrication professionals reach for this belt when surface prep speed matters without sacrificing control.

This belt is a direct fit for Dynabrade narrow belt tools that accept 1/2 inch wide by 12 inch length belts. Typical applications include weld blending on pipe and tubing, deburring machined parts, and contour finishing in tight access areas. The medium grit is a common choice for first-pass metal finishing before stepping down to finer grits. It is used in metal fabrication shops, HVAC sheet metal work, pipefitting, and maintenance environments where portable belt tools are standard equipment.

Key Features

• Zirconia alumina grain provides aggressive, self-sharpening cut for extended belt life on metal
• Y-weight polyester cloth backing resists tearing and flexing under high tool pressure
• 80 grit medium grade balances fast material removal with controllable surface finish
• 1/2 x 12 inch size fits Dynabrane narrow belt file sanders and similar tools
• Coated abrasive construction for consistent grain coverage and uniform scratch pattern

Compatibility

Designed as a replacement coated abrasive belt for portable belt file sanders and narrow belt tools accepting a 1/2 inch wide by 12 inch length belt.

Installation Notes

Abrasive belts on pneumatic or electric narrow belt tools should be installed with the arrow on the belt backing aligned to the direction of rotation marked on the tool. Power down or depressurize the tool completely before changing belts. Inspect the drive and idler rollers for wear or debris before seating the new belt. Eye protection and appropriate respiratory protection should be worn during grinding and deburring operations per applicable safety standards.
