3M 7010516278 Abrasive Belt 120 Grit 25x48 Aluminum Oxide

Product Description

The 3M 7010516278 is a coated abrasive belt designed for heavy-material removal and finishing applications on wide belt sanders and industrial grinding equipment. Built on a Series 340D platform, it uses aluminum oxide grain bonded to an X-weight cloth backing with an open coat density. At 120 grit, the belt falls in the fine grade range, making it well-suited for intermediate stock removal and surface prep before final finishing passes. The cloth backing provides flexibility and durability under the heat and tension generated in sustained belt sanding operations. Dry operation only.

This belt is intended for use in industrial, fabrication, and woodworking environments where wide-format belt sanders are standard equipment. The 25-inch by 48-inch format fits large stationary wide belt sanding machines common in cabinet shops, millwork facilities, and metal fabrication shops. At 120 grit, it handles tasks such as leveling glue lines, removing mill marks, and preparing wood or metal surfaces for coating. Licensed tradespeople and skilled shop technicians are the typical end users for this belt size and grit combination.

Key Features

• 120 grit fine grade aluminum oxide for controlled stock removal and surface prep
• Open coat density reduces loading and extends belt life in resinous or soft materials
• X-weight cloth backing delivers strength and flexibility under high-tension operation
• Dry operation design engineered for standard wide belt sanding machines
• Series 340D construction for consistent grain distribution and cut rate

Compatibility

Designed as a replacement or consumable abrasive belt for wide belt sanding machines that accept a 25-inch by 48-inch belt format. Confirm platen and drive roller dimensions on the target machine before installation.

Installation Notes

Installation should be performed by qualified shop personnel familiar with wide belt sander maintenance procedures. Power down and lock out the machine before removing or installing any abrasive belt. Verify belt tracking tension and directional arrow alignment with the drive roller rotation before resuming operation. Inspect the platen, contact drum, and idler roller for wear or debris that could cause premature belt failure.
