Norton 66261109697 Psa Disc 9 in 180 Grit Aluminum Oxide

Product Description

The NORTON 66261109697 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing and material removal on flat and contour surfaces. At 9 inches in diameter, this disc carries a 180-grit aluminum oxide abrasive rated as very fine grade, making it well-suited for fine stock removal, surface prep, and pre-finishing passes. The cloth backing — rated X-weight — provides flexibility and durability under load. The PSA mount allows fast disc changes on compatible backup pads without hook-and-loop hardware. Licensed tradespeople and production grinding shops typically reach for this disc when a consistent, refined scratch pattern is needed ahead of finishing coats or polishing steps.

This disc is used in metalworking, woodworking, and general fabrication environments where a 9-inch PSA backup pad is already installed on a random orbital, disc sander, or bench grinder. The flexible cloth backing conforms to slightly contoured workpieces, reducing the risk of uneven cut patterns. The 180-grit aluminum oxide abrasive is appropriate for smoothing welds, removing light surface oxidation, leveling wood grain, or blending body filler in light fabrication work. No vacuum holes are included, so this disc is suited for non-dust-extraction setups or where the backup pad itself does not require hole alignment.

Key Features

• 9-inch diameter PSA disc — mounts directly to adhesive-compatible backup pads
• 180-grit aluminum oxide abrasive — very fine grade for finish prep and scratch refinement
• X-weight cloth backing — flexible enough for mild contours, durable under sustained contact pressure
• No vacuum holes — simplified setup on non-extraction disc sanders
• Series R228 construction — consistent grit distribution across the disc face
• Brown disc color aids visual inspection of wear during use

Compatibility

Designed for use with 9-inch PSA (pressure-sensitive adhesive) backup pads on disc sanders, random orbital machines, and similar rotary finishing equipment. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by the equipment operator or finishing technician — no licensed trade certification is required for disc changes. Power down and unplug or de-energize the sander before removing or applying the disc. Clean the backup pad surface of debris and adhesive residue before applying the new disc to ensure full contact and proper adhesion. Do not exceed the RPM rating of the backup pad or sander when using PSA discs.
