Norton 78072750287 Abrasive Belt 36 Grit 4x132 in Zirconia

Product Description

The NORTON 78072750287 is a coated abrasive belt designed for heavy stock removal in industrial and trade grinding, blending, and finishing applications. Built on a polyester backing with a closed-coat zirconia alumina abrasive, this belt runs at 36 grit — extra coarse — making it well suited for aggressive material removal on metal, weld seams, and hard surfaces. The zirconia alumina grain is self-sharpening under pressure, which helps the belt cut consistently throughout its service life. At 4 inches wide and 132 inches in overall length, this belt fits wide-belt and large-platen machines common in fabrication and industrial finishing environments. It is rated for both wet and dry operation.

This belt is a practical choice for metal fabrication shops, welding operations, and industrial maintenance environments where fast, aggressive stock removal is required. The R884P series designation indicates Norton's industrial-grade polyester-backed line, built for demanding machine use. Wet or dry compatibility gives operators flexibility depending on the machine setup and workpiece requirements. Typical users include metal fabricators, machinists, and industrial maintenance technicians working with ferrous and non-ferrous materials on wide-belt sanders or large belt grinders.

Installation Notes

Installation should be performed by a qualified machine operator or maintenance technician familiar with the specific belt grinder or wide-belt sander in use. Power down and lockout the machine before changing belts, following OSHA lockout/tagout procedures. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Inspect the platen and contact wheel for wear before mounting a new belt.
