Norton 66261136352 Psa Disc 8 in 50 Grit Aluminum Oxide

Product Description

The NORTON 66261136352 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive stock removal and surface preparation on metal, wood, and composites. The disc features an aluminum oxide abrasive bonded to an X-weight cloth backing, which provides high tensile strength and flexibility for contoured or flat surface work. At 50 grit, this is a coarse-grade disc suited for fast cutting and heavy material removal. The PSA mount allows quick application to a compatible backup pad without hardware. This disc is used by machinists, fabricators, and finishing technicians in production and shop environments.

This disc is a fit for stationary and portable disc sanders equipped with an 8-inch PSA-compatible backup pad. The coarse 50-grit cut makes it appropriate for weld grinding, rust removal, paint stripping, and initial shaping passes. The X-weight cloth backing handles lateral stress during aggressive passes without tearing. The maroon disc color is characteristic of the NORTON R228 series. No vacuum holes are present, so it is intended for use on solid backup pads without dust extraction ports.

Key Features

Compatibility

Designed as an OEM-style replacement or consumable for disc sanders and finishing machines equipped with an 8-inch PSA (sticky-back) backup pad.

Installation Notes

Installation is performed by fabricators and metalworking technicians. Before mounting the disc, ensure the sander or grinder is powered off and disconnected from its power source. Clean the backup pad surface of any adhesive residue from the previous disc before applying the new PSA disc to ensure full contact and a secure bond. Do not exceed the maximum RPM rating of the backup pad or machine, and verify the disc is fully seated before resuming operation.
