Norton 78072750499 Abrasive Belt 50 Grit 8x107 in

Product Description

The NORTON 78072750499 is a coated abrasive belt designed for aggressive material removal on wide-belt and stroke-sanding machines. Built on a heavyweight polyester cloth backing with Y-weight designation, this belt handles high-tension applications without stretching or tearing. The zirconia alumina abrasive grain runs in a closed-coat configuration, delivering fast, consistent stock removal at 50 grit coarse grade. At 8 inches wide and 107 inches long, this belt suits industrial and shop floor operations where throughput and belt life matter. Suitable for wet or dry use.

This belt is used in industrial grinding and sanding operations on metal, wood composites, and other demanding substrates. The R824 series construction makes it a common choice for wide-belt finishing machines and large stationary stroke sanders found in fabrication shops, millwork facilities, and metal service centers. The closed-coat grain layout maximizes surface contact per pass, reducing the number of passes needed to hit a target finish. Licensed tradespeople and industrial maintenance machinists are the typical installers and operators.

Installation Notes

Inspect the contact drum, platen, and tracking components for wear before mounting a new belt. Confirm belt tracking adjustment before returning the machine to full operating speed.
