3M 7100231548 Cloth Abrasive Belt 340D 80 Grit

Product Description

The 3M 7100231548 is an aluminum oxide abrasive cloth belt designed for general-purpose material removal and surface finishing in woodworking applications. Built on an X-weight cloth backing, it delivers durability under sustained load. The open-coat construction resists loading and clogging, extending belt life when working softer materials. Resin bonding adds heat resistance, keeping the abrasive layer stable during prolonged use. At 52 inches by 75 inches with an 80-grit cut, this belt suits wide belt sanders and large drum sanders common in millwork, cabinet, and furniture production environments.

This belt is intended for use on wide belt or drum sander setups in residential and light commercial woodworking operations. The 340D formulation performs best on soft woods, though the durable cloth backing supports use on harder materials where moderate stock removal is needed. The washable construction allows periodic cleaning to restore cutting performance before the belt reaches end of life, lowering per-use cost in high-volume shop environments.

Key Features

• Aluminum oxide mineral for consistent cut rate and wear resistance
• Open-coat construction resists loading on resinous and soft wood species
• X-weight cloth backing provides tensile strength for high-tension belt sander operation
• Resin bond system improves heat resistance during extended runs
• Washable belt extends usable life in production environments
• 80 grit suited for aggressive stock removal and surface leveling

Compatibility

Designed as a replacement-style abrasive belt for wide belt and drum sanders accepting a 52-inch by 75-inch belt size. Verify machine belt tension and tracking specifications before installation.

Installation Notes

Belt installation should be performed by qualified shop personnel familiar with the sander manufacturer's tension and tracking procedures. Power down and lock out the sander before changing belts. Inspect the platen, idler rolls, and tracking system for wear before installing a new belt. Confirm belt direction of travel matches the arrow marked on the belt seam if present.
