Superior Abrasives A020460 Psa Disc 60 Grit 20 Inches

Product Description

The SUPERIOR ABRASIVES A020460 is a 20-inch pressure-sensitive adhesive (PSA) disc designed for aggressive material removal on a wide range of surfaces. Built with a zirconia alumina abrasive on an X-weighted cloth backing, this disc delivers the durability and cut rate demanded in heavy grinding and finishing applications. At 60 grit, it falls in the medium grade range, making it well-suited for stock removal, weld blending, and surface preparation. The flexible construction allows the disc to conform to workpiece contours. Maximum rated speed is 1,720 RPM. It ships as a single disc per package and weighs 1.7 pounds.

This disc is intended for use on platen grinders in industrial and fabrication environments. Compatible material applications include composite material, exotic alloy, ferrous metal, non-ferrous metal, plastic, and stainless steel. The PSA adhesive backing mounts directly to a flat platen without additional fasteners, making changeovers fast on production floors. It is a practical choice for metal fabrication shops, aerospace component finishing, and general industrial grinding tasks where consistent cut and disc longevity are priorities.

Key Features

• Zirconia alumina abrasive for high cut rate and extended disc life on tough materials
• X-weighted cloth backing provides rigidity and support during aggressive grinding
• Flexible construction allows the disc to conform to workpiece surfaces
• 60 grit medium grade suited for stock removal and weld blending
• Pressure-sensitive adhesive backing for fast, tool-free platen mounting
• Rated for platen grinder use at up to 1,720 RPM

Compatibility

Designed for use with platen grinders. Compatible with composite material, exotic alloy, ferrous metal, non-ferrous metal, plastic, and stainless steel workpieces.

Installation Notes

Installation is performed by grinding machine operators or maintenance technicians. Power down and de-energize the grinder completely before changing discs. Peel the liner from the PSA backing and press the disc firmly and evenly onto the platen to ensure full adhesive contact and prevent disc separation during operation. Verify that the machine RPM rating does not exceed the 1,720 RPM maximum rating of this disc before resuming operation.
