Norton 78072727573 Abrasive Belt 40 Grit 3/4x20-1/2 in

Product Description

The NORTON 78072727573 is a coated abrasive belt designed for aggressive stock removal on metal, wood, and composite surfaces. Built on an X-weight rayon cloth backing, it handles the flex and tension demands of handheld and stationary belt sanders. The aluminum oxide abrasive grain is bonded in a closed-coat configuration at 40 grit, placing it in the extra coarse grade range. This belt measures 3/4 inches wide by 20-1/2 inches in overall length and supports both wet and dry operation, giving the installer flexibility depending on workpiece material and finishing requirements. It is a standard replacement belt for small belt sanders and file sanders used in metalworking, fabrication, and general maintenance environments.

This belt fits light-duty and portable belt sanding tools that accept the 3/4 inch by 20-1/2 inch format. It is commonly used in metal fabrication shops, HVAC fabrication, plumbing rough-in, and general maintenance settings where weld seam grinding, edge deburring, or surface preparation is needed. The wet or dry rating makes it suitable for wet grinding applications where coolant or water is used to reduce heat buildup at the contact zone. It is part of the Norton R283 series.
