Norton 66261144091 Quick-change Disc 120 Grit 1 Inch

Product Description

The NORTON 66261144091 is a coated quick-change abrasive disc designed for use with Speed-Lok TR (Type R) attachment systems. Measuring 1 inch in diameter, this disc is backed with a flexible cloth backing and loaded with zirconia alumina abrasive grain at 120 grit, placing it firmly in the fine grade range. It is rated for a maximum of 30,000 RPM, making it compatible with high-speed rotary die grinders and similar pneumatic or electric tools. The green color-coding and black button are consistent with the R801 series. Fabricators, welders, and metal finishing technicians use this disc for light material removal, blending, and surface conditioning work on tight or contoured surfaces.

This disc is suited for precision metalworking applications where a small-diameter, high-speed abrasive is needed. The 1-inch format fits compact die grinders used in confined areas such as weld joints, pipe sections, and recessed cavities. The flexible cloth backing conforms to irregular surface profiles without loading. Fine 120-grit zirconia alumina is appropriate for final blending passes, scratch removal, and pre-inspection surface prep on steel, stainless, and other ferrous and non-ferrous metals. This is a single-piece package item sold in minimum order quantities of 100 units.

Installation Notes

Installation is performed by metal fabricators or machinists using a Type R quick-change mandrel seated in a die grinder. Verify the grinder's free-speed rating does not exceed 30,000 RPM before mounting the disc. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of wear through the backing. Always use appropriate eye and face protection when operating rotary abrasive tools.
