3M 7100033193 Abrasive File Belt 36 Grit Cubitron Ii 786F

Product Description

The 3M 7100033193 is a Cubitron II 786F abrasive file belt designed for precision grinding and material removal on hard metals. It uses 3M Precision Shaped Grain technology, a ceramic and aluminum oxide blend with uniformly sized, vertically oriented grains resin-bonded to a heavy-duty backing. This construction allows the belt to slice through metal consistently, run cooler than conventional abrasives, and deliver roughly twice the belt life of standard options. It measures 13 inches in length and 3/8 inch in width at a 36 grit rating. Licensed fabricators, welders, and metal finishing technicians are the primary users.

This file belt is engineered for use with the 3M File Belt Sander in metal fabrication and repair applications. Typical tasks include grinding out rivets, removing spot welds, and blending welds on high-strength steel. The cooler running action reduces the risk of metal discoloration, oxidation, and heat-related stress cracks, making it well suited for finish-sensitive work on structural and body panels. The integrated grinding aid further maintains cutting performance during aggressive stock removal on hard alloys.

Key Features

• Cubitron II ceramic and aluminum oxide grain blend for fast, consistent cut on hard metal
• Precision Shaped Grain orientation slices material rather than plowing, reducing heat generation
• Resin bond with grinding aid keeps the belt cutting cool and sharp throughout its life
• Cooler operation reduces risk of metal discoloration, oxidation, and heat-related stress cracks
• Heavy-duty backing supports aggressive applications including rivet grinding and spot weld removal
• Approximately twice the belt life compared to conventional abrasive belts

Compatibility

Designed for use with the 3M File Belt Sander. Compatible with file belt sander tools accepting a 13-inch by 3/8-inch belt format.

Installation Notes

Belt installation and replacement should be performed by a qualified technician with the tool powered off and disconnected from the air or power source. Confirm belt tracking and tension before resuming operation. Eye protection, hearing protection, and appropriate gloves are standard PPE for grinding and material removal tasks. Follow applicable OSHA and facility safety guidelines for abrasive tool use.
