Superior Abrasives A017782 Psa Disc 6 in 36 Grit

Product Description

The SUPERIOR ABRASIVES A017782 is a 6-inch pressure-sensitive adhesive (PSA) sanding disc designed for aggressive material removal on a range of metal and composite substrates. Built with zirconia alumina abrasive at 36 grit, this disc falls in the very coarse grade range, making it well suited for heavy stock removal, weld blending, and surface preparation work. The X-weight cloth backing provides the rigidity and durability needed to hold up under high-load grinding passes. Rated to a maximum of 10,000 RPM, it is engineered to perform on orbital disc sanders without delamination or premature breakdown.

This disc is intended for use in metal fabrication, aerospace, and general industrial settings where fast, consistent cutting action is required. Compatible materials include ferrous metals, stainless steel, non-ferrous metals, exotic alloys, composite materials, and plastics. The PSA backing allows for quick disc changes on compatible platens, reducing downtime during production runs. The flexible construction conforms slightly to irregular surfaces, making it useful for contoured workpiece profiles as well as flat stock.

Compatibility

Designed for use with orbital disc sanders accepting 6-inch PSA sanding discs. Confirmed compatible material applications include composite material, exotic alloys, ferrous metal, non-ferrous metal, plastic, and stainless steel.

Installation Notes

A licensed or qualified abrasives user should inspect the platen surface for damage or contamination before applying the PSA disc. Clean the platen with a lint-free cloth to ensure full adhesive contact and prevent disc slippage during operation. Never exceed the rated 10,000 RPM maximum speed. Allow the disc to reach a full stop before removing or replacing it on the machine.
