Norton 78072771278 Abrasive Belt 320 Grit 3x24 in

Product Description

The NORTON 78072771278 is a coated abrasive belt designed for dry precision finishing and surface preparation work. It measures 3 inches wide by 24 inches long and carries a 320 extra fine grit aluminum oxide abrasive. The closed-coat construction delivers consistent scratch patterns and smooth finishes on metal, wood, and composites. The X-weight cloth backing resists tearing and flexing under load, making it suitable for both handheld belt sanders and stationary grinders. This belt is installed by machinists, fabricators, millwrights, and finish carpenters who need reliable cut performance at higher grit ranges.

This belt is appropriate for finishing passes on ferrous and non-ferrous metals, hardwoods, and engineered materials in shop and light industrial environments. The 320 grit extra fine rating makes it well-suited for final surface conditioning, paint prep, and deburring where a finer scratch pattern is required. It is intended for dry operation only and performs best on belt sanders accepting a 3 by 24 inch belt format. The R228 series designation confirms Norton-standard construction for this belt size and abrasive combination.
