Norton 66261138205 Quick-change Disc 36 Grit 3 in

Product Description

The NORTON 66261138205 is a coated abrasive quick-change disc from the Gemini R766/R228 series, designed for fast attachment and removal on handheld disc sanders using the Speed-Lok TS (Type II / Type S) system. At 36 grit, this is an extra coarse disc suited for aggressive material removal, deburring, and surface conditioning. The abrasive grain is aluminum oxide, bonded to a flexible X/Y-weight two-ply cloth and polyester backing that holds up under lateral and directional pressure. Maximum rated speed is 20,000 RPM. The disc is brown with a silver mounting button and is not trimmable.

This disc is built for metalworking applications in fabrication shops, maintenance environments, and field service work. It performs on 300 and 400 series stainless steel, aluminum, brass, bronze, soft carbon steels, hard carbon steels, and titanium. The extra coarse 36-grit specification makes it a primary choice for weld blending, scale removal, and initial deburring passes on hard and soft metals. It mounts to handheld disc sanders equipped with the Speed-Lok TS quick-change arbor system, allowing fast disc swaps without tools.

Installation Notes

Installation and disc changes should be performed with the sander powered off and disconnected from its power source. Align the disc button with the arbor receiver and engage the locking mechanism fully before operation. Verify the sander spindle speed does not exceed the 20,000 RPM disc rating before use. Inspect the disc for damage or delamination before each use and discard any disc showing cracks, tears, or separation of the backing.
