3M 7010308698 Abrasive Belt 132x3 Inch 150 Grit Cotton

Product Description

The 3M 7010308698 is a Cubitrona II 723D cloth abrasive belt designed for precision grinding, blending, and finishing on demanding applications. Built on a flexible J-weight cotton backing, this belt conforms to tight contours and complex geometries where rigid abrasives fall short. The abrasive mineral is 3M Precision Shaped Grain, which delivers a faster, more consistent cut and significantly longer service life compared to conventional aluminum oxide belts. At 150 grit, this belt is suited for medium-to-fine material removal and surface finishing. The durable resin bond resists heat-related breakdown, keeping the abrasive cutting longer between changeovers.

This belt is built for applications requiring conformability and consistent finish quality on contoured or irregular surfaces. Typical use cases include finishing medical instruments, aerospace components, and precision-machined parts where surface integrity matters. The 132-inch length and 3-inch width fit standard wide-belt and stroke-sander configurations used in metal fabrication and industrial finishing shops. It is suitable for dry-use applications only. Grinding and finishing technicians in metalworking, medical device manufacturing, and precision fabrication environments are the primary users.

Key Features

• 3M Precision Shaped Grain delivers up to 2x longer life compared to comparable aluminum oxide belts
• J-weight cotton backing provides flexibility for blending contours and finishing complex parts
• 150 grit rating suited for medium-to-fine stock removal and surface conditioning
• Durable resin bond resists heat deterioration, extending abrasive life
• Dry-use construction — not rated for wet or lubricated applications
• Lighter backing reduces cost per part and minimizes time lost to belt changeovers

Compatibility

Designed for use on wide-belt sanders and stroke sanders accepting 132-inch by 3-inch abrasive belts in dry metalworking and finishing applications.

Installation Notes

Installation should be performed by a qualified machine operator familiar with the sanding or grinding equipment in use. Power down and lockout the machine before changing belts. Verify belt tracking and tension per the equipment manufacturer's guidelines before resuming operation. Inspect the belt for tears or edge damage before each use and replace if wear is uneven or the grain is glazed.
