Norton 66261136717 Psa Disc 24 in 40 Grit Aluminum Oxide

Product Description

The NORTON 66261136717 is a pressure-sensitive adhesive (PSA) abrasive disc designed for heavy-duty grinding and surface preparation. Measuring 24 inches in diameter, it carries a 40-grit aluminum oxide abrasive on an X-weight cloth backing, placing it firmly in the coarse cutting category. The PSA mounting system allows fast disc changes on compatible floor grinders and large-format sanding machines. This disc is well suited for licensed flooring contractors, industrial maintenance techs, and surface prep crews who need aggressive material removal on large, flat work surfaces.

This disc is intended for use on large-diameter rotary and orbital floor machines common in commercial and industrial surface preparation. Typical applications include concrete floor leveling, wood floor resurfacing, removing old coatings, and initial stock removal on wide panel or flat-stock fabrication. The flexible cloth backing conforms slightly to surface irregularities, helping maintain consistent contact across the full 24-inch face. No vacuum holes are included, making this disc appropriate for machines without dust-extraction ports at the platen.

Compatibility

Designed as an OEM-style replacement or consumable for large-format PSA rotary floor machines and grinders that accept 24-inch adhesive-mount abrasive discs.

Installation Notes

Installation is performed by flooring or surface preparation technicians. Before mounting, power down the machine and disconnect it from its power source completely. Clean the platen surface of any adhesive residue from the previous disc to ensure full, even contact across the 24-inch face. Avoid touching the adhesive surface before application, as contamination reduces holding strength during operation.
