3M 7100138137 Cloth Band 341D P120 X-weight Abrasive Belt

Product Description

The 3M 7100138137 is a closed-coat aluminum oxide cloth abrasive band designed for demanding material removal in metalworking and woodworking applications. Built on an X-weight cloth backing, this band delivers the rigidity and durability needed to hold up under high-contact grinding and finishing work. Resin bonding provides heat resistance, helping the abrasive layer maintain integrity during extended use. At a P120 grit rating, this band targets intermediate finishing work, removing surface scratches and preparing workpieces for final finishing stages. It is sized at 1/2 inch wide by 1 inch long, fitting compact band filing and abrasive machining tools used by machinists, metalworkers, and woodworkers in both shop and production environments.

This abrasive band is suited for general-purpose grinding and finishing on metal and wood substrates. It performs particularly well on harder wood species where consistent stock removal and surface quality are required. The closed-coat construction maximizes abrasive grain coverage across the belt face, improving cutting efficiency on dense, smooth-grained materials. Typical applications include deburring, blending welds, shaping edges, and surface preparation on metal parts and wood components. This band is sold in quantities of 100 per unit of measure, making it appropriate for production shops and service operations with ongoing abrasive consumption.

Compatibility

Designed as an OEM-style replacement or production-supply abrasive band for compact band filing and abrasive machining tools that accept a 1/2 inch x 1 inch abrasive band format.

Installation Notes

Installation is performed by machinists or shop technicians familiar with abrasive tooling. Power down and de-energize the tool before changing abrasive bands. Confirm the tool spindle or drive assembly is compatible with the 1/2 inch x 1 inch band size before mounting. Inspect the band for damage before use and do not exceed the tool manufacturer's rated operating speed.
