Norton 66261138316 Psa Disc 10 in 60 Grit Zirconia Alumina

Product Description

The NORTON 66261138316 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Part of the R821 series, this disc features a zirconia alumina abrasive grain at 60 grit, a medium-to-coarse cut suited for stock removal and surface conditioning. The Y-weight cloth backing delivers high tensile strength and flexibility, allowing the disc to conform to contoured workpieces without tearing under load. At 10 inches in diameter, it is sized for large-disc grinders and sanders commonly used in fabrication shops, metal service centers, and woodworking production lines. Licensed tradespeople and skilled fabricators are the primary installers and operators.

This PSA disc is intended for use on stationary and portable disc sanders equipped with a 10-inch PSA platen. The self-adhesive backing mounts directly to the platen without mechanical hardware, making disc changes fast during production runs. Typical applications include weld blending, rough shaping, and surface prep prior to finishing operations on ferrous metals, aluminum, hardwood, and engineered wood panels. The flexible cloth backing makes it suitable for applications where a rigid disc would chatter or lift on uneven workpiece geometry.

Key Features

• Zirconia alumina grain provides aggressive, self-sharpening cut for extended disc life on hard materials
• Y-weight cloth backing resists tearing and flexes to follow contoured surfaces
• Pressure-sensitive adhesive mount for fast, tool-free disc changes on compatible platens
• 60 grit medium grade suited for stock removal and weld blending operations
• No vacuum holes maintains full abrasive surface contact across the entire 10-inch diameter
• Blue disc color for quick visual identification of grit level on the shop floor

Compatibility

Designed for use with 10-inch PSA disc sanders and grinders fitted with a smooth adhesive-compatible platen. Confirm platen diameter and PSA backing compatibility before mounting.

Installation Notes

Power down and lock out the sander before removing a spent disc or mounting a new one. Peel the release liner from the PSA backing and align the disc squarely to the platen before pressing firmly to seat the adhesive. Ensure the platen surface is clean and free of adhesive residue from previous discs to maintain proper bond. Always verify disc speed rating against the machine's maximum RPM before operation.
