3M 7100138157 Cloth Band 341D 3x3 in 36 Grit X-weight

Product Description

The 3M 7100138157 is an aluminum oxide cloth band in the 341D series, designed for demanding material removal in metalworking and woodworking applications. Built on a durable X-weight cloth backing and resin bonded for heat resistance, this closed-coat abrasive delivers consistent cut and long service life under high-pressure grinding conditions. Measuring 3 inches by 3 inches and rated at 36 grit, it is well suited for aggressive stock removal on ferrous metals, non-ferrous metals, and harder wood species. Fabricators, welders, and finish carpenters rely on this format for deburring, blending, and shaping work.

This cloth band is intended for use on band sanders and similar abrasive tooling found in metal fabrication shops, cabinet shops, and general woodworking operations. The 36-grit designation places it in the coarse range, making it most effective for initial material removal and surface preparation rather than fine finishing. It performs particularly well on harder woods and on metal surfaces requiring fast, controlled stock removal before progression to finer grits.

Key Features

• Aluminum oxide grain in a closed-coat configuration for consistent, aggressive cutting action
• X-weight cloth backing provides high tensile strength and flexibility under load
• Resin bond construction resists heat buildup during extended grinding or sanding cycles
• 36 grit rating suited for coarse stock removal on metal and hard wood substrates
• 3 inches by 3 inches format compatible with standard band sander tooling

Compatibility

Designed as a general-purpose abrasive band for use on band sanders and abrasive finishing equipment accepting a 3-inch by 3-inch cloth band format.

Installation Notes

Abrasive bands should be installed and replaced by qualified operators following the tool manufacturer's mounting instructions. Power down and disconnect the sander from its power source before changing abrasive bands. Inspect the tool's drive and idler wheels for wear or debris before installing a new band. Always confirm band tracking is properly adjusted before resuming operation.
