Norton 66261125615 Psa Disc 9 in 120 Grit Aluminum Oxide

Product Description

The NORTON 66261125615 is a 9-inch pressure-sensitive adhesive (PSA) abrasive disc designed for stock removal and surface finishing on a wide range of substrates. Built on an X-weight cloth backing, it delivers the rigidity and durability needed for aggressive grinding and blending applications. The aluminum oxide abrasive grain is bonded at 120 grit, placing it in the fine grade range and making it well-suited for intermediate finishing passes where scratch pattern control matters. The PSA mount system allows fast disc changes on compatible backup pads without hardware. Licensed trade professionals and experienced fabricators are the typical users of this product.

This disc is used in metal fabrication shops, woodworking operations, and general surface prep environments. The 9-inch diameter fits standard random orbital and disc sanders equipped with PSA backup pads of the same diameter. Its flexible, cloth-backed construction conforms moderately to contoured surfaces, making it useful for both flat stock finishing and light profile work. The fine 120-grit cut makes it appropriate for intermediate or pre-finishing stages following coarser stock removal. No vacuum holes are present, so this disc is intended for non-vacuum sanding setups.

Key Features

• 9-inch diameter PSA disc for tool-free adhesive mount on compatible backup pads
• 120 grit aluminum oxide grain for fine-grade surface finishing and scratch refinement
• X-weight cloth backing provides added durability and resistance to tearing under load
• Flexible construction allows moderate conformance to contoured work surfaces
• No vacuum holes — suited for closed-face, non-vacuum disc sanding applications
• Brown disc color; part of the NORTON R228 series

Compatibility

Designed as a direct-fit PSA abrasive disc for 9-inch backup pads and disc sanders that accept pressure-sensitive adhesive mount consumables. No vacuum hole pattern is present, so the backup pad must be a solid-face or non-perforated type.

Installation Notes

Installation is performed by a machinist, fabricator, or trades professional familiar with abrasive tooling. Before mounting, ensure the sander or grinder is powered off and unplugged. Clean the backup pad face of debris or adhesive residue from the previous disc before applying the new PSA disc to ensure full contact and even adhesion. Do not exceed the maximum RPM rating of the tool or backup pad when operating this disc.
