3M 7100035469 Cubitron Ii 786F File Belt 80 Grit

Product Description

The 3M 7100035469 is a Cubitron II 786F abrasive file belt engineered for demanding metalworking applications on professional-grade file belt sanders. Built on a heavy-duty backing with resin-bonded Precision Shaped Grain, this belt delivers consistent material removal, cooler operation, and extended service life compared to conventional abrasive belts. The ceramic and aluminum oxide blend grain is precisely shaped, uniformly sized, and vertically oriented to slice through hard metal efficiently. At 80 grit, it is suited for aggressive stock removal tasks while minimizing heat buildup at the workpiece surface. Licensed metalworking technicians, welders, and fabricators are the primary installers and users of this belt.

This file belt is designed for use with file belt sander tools in metal fabrication and maintenance environments. Typical applications include grinding out rivets, removing spot welds, and general surface preparation on high-strength steel components. The integrated grinding aid further reduces heat generation when working on hard or heat-sensitive metals, lowering the risk of discoloration, oxidation, and heat-related stress fractures in the base material. This belt is suited for both production shop and field repair scenarios where consistent cut rate throughout belt life is essential.

Key Features

• Cubitron II Precision Shaped Grain ceramic and aluminum oxide blend for fast, consistent cut
• Vertically oriented, uniformly sized grains slice through hard metal with reduced friction
• Resin bond and grinding aid promote cooler operation, reducing risk of metal discoloration and stress cracks
• Heavy-duty backing supports extended belt life and dimensional stability during use
• 80 grit configuration suited for aggressive material removal including rivet grinding and spot weld removal
• Consistent performance maintained throughout the full usable life of the belt

Compatibility

Designed for use with the 3M file belt sander as an OEM-style replacement abrasive belt for metal fabrication and maintenance applications.

Installation Notes

Belt installation and replacement should be performed by qualified metalworking or fabrication professionals familiar with file belt sander operation. Disconnect or power down the tool completely before changing belts and verify belt tracking alignment before resuming operation. Always wear appropriate PPE including eye protection and gloves when handling abrasive belts and operating grinding equipment. Follow the tool manufacturer's guidelines for belt tension and speed ratings.
