Norton 66261121043 Quick-change Disc 60 Grit 1.5 in

Product Description

The NORTON 66261121043 is a Speed-Lok TR quick-change abrasive disc designed for fast stock removal, weld blending, and deburring across a wide range of materials. Part of the R860 series, it features a zirconia alumina abrasive grain with a self-lubricating treatment that accelerates cut rate, extends disc life, and reduces heat buildup during aggressive grinding. The disc measures 1.5 inches in diameter and carries a 60-grit medium-coarse cut rating. It is mounted via a Type R attaching system for rapid tool-free disc changes. The rigid, heavy Y-weight polyester backing resists flex and maintains consistent contact on flat and contoured workpieces. Licensed HVAC techs, fabricators, and metalworkers specify this disc for production-level surface prep.

This disc is suited for handheld disc sander applications in both shop and field environments. It performs on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, fiberglass and composites, and hard and soft woods. The blue coated surface and rigid backing make it especially effective on stainless and cast iron where heat control and consistent cut geometry matter. Sold individually, with a minimum order quantity of 100 units, making it appropriate for stocking in shop or fleet supply.

Installation Notes

Installation is performed by metalworkers, fabricators, or maintenance technicians using a handheld disc sander with a Type R quick-change arbor. Confirm the tool spindle speed does not exceed the 30,000 RPM disc rating before mounting. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or backing separation. Always wear appropriate PPE including eye protection and gloves when operating abrasive equipment.
