Norton 66261183813 Psa Disc 320 Grit 5 Inches

Product Description

The NORTON 66261183813 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for consistent material removal and fine surface finishing. Part of the A296 series, this 5-inch disc is constructed with an aluminum oxide abrasive bonded to a B-weight paper backing, delivering a flexible yet stable cutting surface. At 320 grit, it falls in the extra fine grade range, making it well-suited for finish sanding, light stock removal, and surface prep before sealing or coating. Rated to 15,000 RPM, the disc is designed for safe use at the speeds common to random orbital sanders in active shop and field environments.

This disc is intended for use with random orbital sanders in residential and commercial applications where a refined surface finish is required. Typical scenarios include furniture finishing, automotive bodywork prep, cabinetry sanding, and general surface smoothing on wood or compatible substrates. The PSA backing allows for fast disc changes without the need for hook-and-loop fasteners. Each package contains 100 discs, sold individually by the package. This product does not include vacuum holes, so it is best paired with sanders used in open-air or ventilated environments.

Compatibility

Designed for use with random orbital sanders that accept 5-inch PSA-style abrasive discs. Verify that the sanding pad on the tool is PSA-compatible before installation.

Installation Notes

Ensure the sander is powered off and unplugged before mounting or removing discs. Clean the PSA pad surface of debris or adhesive residue before applying a new disc to ensure proper adhesion and even contact. Do not exceed the rated 15,000 RPM maximum speed. Dispose of worn discs promptly, as degraded abrasive surfaces reduce cut quality and can generate excess heat.
