Norton 66623333515 Abrasive Belt 3/4 X 20-1/2 in Aluminum Oxide

Product Description

The NORTON 66623333515 is a non-woven abrasive belt designed for fine surface finishing, blending, and deburring applications. Part of the Rapid Prep series, it measures 3/4 inches wide by 20-1/2 inches long and uses aluminum oxide abrasive bonded to a polyester cloth backing rated at Y-weight. The very fine grade makes it well suited for light material removal, surface conditioning, and final blending passes where scratch pattern consistency matters. Machinists, fabricators, and metalworking professionals install this belt on portable belt grinders and finishing machines for controlled, repeatable surface prep work.

This belt is used in both wet and dry operating conditions, giving it flexibility across a range of shop environments. The non-woven construction conforms to contours and irregular surfaces more readily than coated abrasive belts, making it a common choice for weld blending, rust removal, and pre-finishing on metal components. It is well matched to light-duty bench-top belt finishing machines and inline portable grinders that accept 3/4 inch by 20-1/2 inch belts in production and maintenance settings.

Installation Notes

Belt replacement should be performed by qualified machine operators or maintenance personnel following the equipment manufacturer's belt-change procedure. Power down and de-energize the machine completely before removing or installing any abrasive belt. Verify belt tracking and tension according to the grinder manufacturer's specifications before returning the machine to service. Inspect the belt for tears or delamination before each use and do not exceed the machine's rated maximum belt speed.
