Norton 66261121023 Quick-change Disc 80 Grit 2 in

Product Description

The NORTON 66261121023 is a 2-inch quick-change abrasive disc from the Gemini R766/R228 series, engineered for use with Speed-Lok TR (Type III) and Type R attachment systems. The disc uses aluminum oxide abrasive on a coated, cloth and polyester backing rated at X/Y weight, providing the rigidity needed for aggressive material removal while remaining flexible enough for contoured surfaces. At 80 grit, it falls in the medium-to-coarse range, making it well suited for deburring, weld prep, surface cleaning, and light stock removal. A two-ply cotton backing construction supports repeated passes on hard and soft metals without premature breakdown. Licensed HVAC, metalworking, and fabrication technicians install this disc on handheld disc sanders as part of routine surface preparation workflows.

This disc is designed for use on a broad range of metals in both shop and field environments. Rated materials include 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The 2-inch diameter is a common size for tight-access deburring, edge cleanup, and detail work on fabricated assemblies. The Speed-Lok TR quick-change attachment allows rapid disc swaps without additional tooling, reducing downtime during multi-step finishing sequences. The disc is non-trimmable and is intended for use on handheld disc sanders only.
