3M 7010326170 Abrasive Belt 320 Grit 2x132 in Aluminum Oxide

Product Description

The 3M 7010326170 is a coated abrasive belt engineered for dry finishing and surface conditioning applications on belt sanders and similar power abrasive equipment. Built on a cloth backing with an X-weight designation, this belt delivers the flexibility and durability needed for contoured or flat workpiece surfaces. It runs aluminum oxide abrasive grain in a closed-coat configuration at 320 grit, placing it firmly in the extra fine grade range. The result is a belt suited for fine stock removal, scratch refinement, and pre-finishing passes where surface finish quality matters. At 0.5 pounds, it is light enough for extended machine use without adding significant rotational load.

This belt is designed for dry operation on stationary or portable belt sanding equipment. The 2-inch width and 132-inch length make it compatible with industrial and bench-top belt sander setups that require longer belts for continuous-duty cycles. Typical applications include metal deburring, wood finishing, composite surface prep, and fine-grinding passes in fabrication or maintenance environments. The Series 341D designation identifies the abrasive cloth line within the 3M coated abrasives family. Trade users in metalworking, woodworking, and general fabrication shops will find this grit level appropriate for final surface preparation before coating or inspection.

Key Features

• 320 grit aluminum oxide grain rated extra fine for refined surface finishing
• Closed-coat configuration maximizes abrasive coverage for consistent scratch patterns
• X-weight cloth backing provides durability and flexibility across flat and contoured surfaces
• Dry operation design keeps grain integrity stable without moisture interference
• Series 341D construction balances cut rate and finish quality for production or maintenance use

Compatibility

Designed for use on belt sanding machines that accept 2-inch wide by 132-inch long abrasive belts in dry operating conditions.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive belt equipment. Power down and lockout the belt sander before changing belts. Verify belt tracking and tension according to the machine manufacturer's guidelines before resuming operation. Inspect the belt for tears or edge damage before each use and replace immediately if defects are found.
