3M 7100066545 341D Abrasive Belt P120 Grit 36x4 Inch

Product Description

The 3M 7100066545 is an aluminum oxide abrasive cloth belt in the 341D series, designed for metal deburring, general metalworking, and woodworking applications. Built on an X-weight cloth backing, it handles heavy sanding and grinding cycles without breaking down. The resin bond holds up under high heat and pressure, making this belt a reliable choice for demanding production and job-site use. At P120 grit, it removes material efficiently while leaving a consistent surface finish on both metal and wood substrates. Licensed tradespeople and shop technicians across fabrication, welding, and millwork operations regularly reach for this belt for intermediate stock removal and surface prep.

This belt is suited for wide belt sanders, edge sanders, and portable belt sanding machines. Its tube-shaped band construction also fits rubber expander wheel attachments used with die grinders and rotary drills, covering inner and outer contours for parting line removal, deburring, and surface blending. It performs on ferrous and non-ferrous metals as well as wood, giving it versatility across multiple trade applications.
