Norton 66261136552 Psa Disc 3 in 100 Grit Aluminum Oxide

Product Description

The NORTON 66261136552 is a 3-inch PSA (pressure-sensitive adhesive) abrasive disc designed for aggressive material removal and surface finishing in trade and industrial applications. Built on an X-weight cloth backing, the disc delivers the rigidity and durability needed for demanding grinding and blending tasks. The abrasive material is aluminum oxide at 100 grit, a fine-grade cut suited for finishing passes on metal, wood, or composite surfaces. The flexible construction allows the disc to conform slightly to contoured workpieces, reducing gouging and improving surface contact. This disc is installed by machinists, fabricators, and finishing technicians using PSA-compatible backup pads.

This disc is used in surface preparation, weld blending, deburring, and finish-sanding operations across metal fabrication shops, woodworking facilities, and general manufacturing environments. The 3-inch diameter fits standard PSA backup pads and rotary tools commonly found in both shop and field settings. The 100-grit aluminum oxide abrasive is well suited for intermediate to final finishing steps where a consistent scratch pattern is required before coating or inspection. No vacuum holes are present, making this disc appropriate for use on solid backup pads without dust-extraction ports.

Key Features

Compatibility

Designed for use with standard 3-inch PSA-style backup pads on rotary grinders, die grinders, and finishing tools. Part of the NORTON R228 series.

Installation Notes

Installation requires a clean, dry PSA backup pad surface — oil, dust, or residue will reduce adhesion and may cause disc separation during use. Press the disc firmly onto the backup pad and allow a brief dwell time before applying load. Always ensure the tool RPM rating meets or exceeds the disc rating before operation. Wear appropriate eye and hand protection per shop safety standards when operating abrasive discs.
