Norton 07660749266 Abrasive Belt 36 Grit 3x21 in Zirconia

Product Description

The NORTON 07660749266 is a coated abrasive belt designed for aggressive material removal on metal, wood, and composite surfaces. It measures 3 inches wide by 21 inches long and cuts at 36 grit, placing it in the very coarse grade range. The abrasive material is zirconia alumina, a self-sharpening grain well suited to high-pressure grinding applications. The belt uses a heavy Y-weight cloth backing for rigidity and durability under demanding conditions. Open coat density reduces loading when working softer or resinous materials. This belt is rated for dry use only and is compatible with portable belt sanders and stationary grinder setups commonly used by fabricators, metalworkers, and finish carpenters.

This abrasive belt fits standard 3 inch by 21 inch belt sander platforms used across residential and light commercial jobsites as well as fabrication shops. The 36 grit rating makes it best suited for rapid stock removal, weld blending, rust removal, and surface conditioning on ferrous and non-ferrous metals. It also performs on hardwood and engineered substrates where coarse initial passes are required before progressing to finer grits. The Series R831 designation identifies it within the NORTON line of cloth-backed industrial abrasive belts.

Installation Notes

Installation should be performed by qualified tradespeople familiar with abrasive tooling and power tool safety. Confirm the belt sander is unplugged or power is isolated before mounting or removing a belt. Verify arrow direction marked on the belt interior matches the intended direction of travel on the sander drum before powering on. Inspect the belt for cracks, tears, or splice separation before each use and remove from service if damage is found.
