Norton 66261121041 Quick-change Disc 36 Grit 1.5 in

Product Description

The NORTON 66261121041 is a quick-change coated abrasive disc designed for aggressive stock removal, weld blending, and deburring on a wide range of metals and wood substrates. Part of the R860 series, this disc features a zirconia alumina abrasive grain on a heavy Y-weight polyester backing, providing rigidity and durability under high-pressure grinding conditions. At 36 grit (extra coarse), it removes material rapidly without loading. The Type R (Speed-Lok TR) attachment system allows fast disc changes on compatible handheld disc sanders. Rated to 30,000 RPM, it suits high-speed applications where downtime between disc swaps is costly. This disc is sold individually with a minimum order quantity of 100 units.

This disc is suited for use on 300 and 400 series stainless steel, aluminum, brass, bronze, fiberglass and composite materials, hard and soft carbon steels, and hard and soft woods. It is intended for use with handheld disc sanders in both shop and field environments. The extra coarse 36-grit grade makes it appropriate for initial weld grinding, heavy deburring, and rapid surface preparation rather than finishing passes. The self-lubricating treatment in the abrasive blend helps reduce heat buildup during extended grinding sessions, which is particularly important when working stainless steel to avoid discoloration or work hardening at the weld zone.

Installation Notes

Installation and disc changes should be performed by qualified operators following the tool manufacturer's RPM rating guidelines — never exceed the 30,000 RPM maximum rating of this disc.

Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always wear appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
