3M 7100138191 Cloth Band 341D 60 Grit 1/2in X 1/2in

Product Description

The 3M 7100138191 is an aluminum oxide cloth band in the 341D series, sized at 1/2 inch x 1/2 inch with a 60 grit X-weight cloth backing. The closed coat construction delivers consistent abrasive coverage across the full belt surface, and the resin bond system adds heat resistance to extend service life under sustained use. This band is designed for metalworking and woodworking applications where a durable, general-purpose abrasive is needed. It is commonly installed on small diameter portable tools, spindle sanders, or drum sander attachments used by machinists, fabricators, and woodworkers.

This cloth band suits general material removal tasks on metal and wood substrates. The 60 grit designation makes it appropriate for moderate stock removal and surface conditioning rather than fine finishing. It performs particularly well on harder wood species where a durable backing and aggressive grit help maintain cut rate. The X-weight backing resists tearing and flex fatigue during extended runs on power tool spindles and rotary drums.

Key Features

• Aluminum oxide abrasive mineral for reliable cut on metal and hardwood
• Closed coat construction for consistent, full-surface abrasive coverage
• X-weight cloth backing provides durability and tear resistance
• Resin bonded for improved heat resistance during high-friction use
• 60 grit for moderate stock removal and surface conditioning
• Compact 1/2 inch x 1/2 inch size fits small spindle and drum sander tooling

Compatibility

Designed as a general-purpose replacement cloth band for small spindle sanders, rotary drum tools, and portable belt sander attachments that accept 1/2 inch x 1/2 inch abrasive bands.

Installation Notes

Installation is performed by the end user or tool operator following the tool manufacturer's band-change procedure. Ensure the tool is fully powered down and unplugged before removing or installing abrasive bands. Confirm the band is seated squarely on the spindle or drum to prevent tracking issues and uneven wear during operation. Inspect the spindle surface for damage or debris before fitting a new band.
