Norton 78072739662 Abrasive Belt 36 Grit 4x132 Ceramic

Product Description

The NORTON 78072739662 is a coated abrasive belt engineered for aggressive stock removal on metal, weld seams, and hard-to-grind surfaces. It measures 4 inches wide by 132 inches long and runs a 36-grit extra coarse ceramic alumina grain on a closed-coat, polyester Y-weight backing. The ceramic alumina abrasive self-sharpens under pressure, maintaining cut rate longer than conventional aluminum oxide belts. This belt is rated for both wet and dry operation, which gives fabricators and grinders flexibility when working with coolant systems or dry grinding setups. Typical users include metal fabricators, weld shops, and maintenance technicians running large stationary or portable belt grinders.

This belt is suited for high-pressure, high-heat grinding applications where fast material removal is the priority. The Series R983 designation places it in a heavy-duty product line intended for industrial and professional use. The extra coarse 36-grit rating makes it appropriate for initial stock removal, weld grinding, and surface prep before stepping down to finer grits. Wet and dry compatibility supports use on both standard dry belt grinders and water-cooled platen or slack-section machines common in fabrication shops.

Installation Notes

Belt installation should be performed by a qualified operator following the grinder manufacturer's tracking and tensioning procedures. Disconnect and lock out power to the machine before changing belts. Confirm belt direction of travel matches the arrow marked on the backing before starting the grinder. Inspect the belt for tears or delamination before each use and replace immediately if damage is found.
