Norton 78072750135 Abrasive Belt 50 Grit 3x132 Zirconia

Product Description

The NORTON 78072750135 is a coated abrasive belt designed for aggressive material removal in industrial and trade grinding applications. Built on a polyester backing with a closed-coat zirconia alumina abrasive, it delivers consistent cut rates across ferrous metals, stainless steel, and other hard materials. At 50 grit, this belt falls in the coarse grade range, making it suited for weld blending, heavy stock removal, and surface conditioning. The belt measures 3 inches wide by 132 inches long and is rated for both wet and dry operation. Fabricators, pipefitters, and metalworkers are the primary installers and users.

This belt fits stationary belt grinders and pipe grinding setups that accept a 3-inch by 132-inch belt. The R884P series construction pairs a durable polyester backing with zirconia alumina grain, a combination well suited to high-pressure contact wheel and platen grinding. Its closed-coat density maximizes grain coverage for faster stock removal on tough base materials. Wet or dry operation gives the technician flexibility depending on the workpiece and grinder setup.

Compatibility

Designed for use on belt grinders and pipe grinders that accept a 3-inch by 132-inch abrasive belt. Suitable for wet or dry grinding of ferrous and non-ferrous metals.

Installation Notes

Installation is performed by the equipment operator or maintenance technician. Before changing belts, power down the grinder and allow all moving parts to come to a complete stop. Verify belt tracking and tension according to the grinder manufacturer guidelines before resuming operation. Inspect the belt splice and backing for damage before each use and do not exceed the maximum operating speed marked on the grinder.
