Norton 66261101660 Psa Disc 12 in 240 Grit Aluminum Oxide

Product Description

The NORTON 66261101660 is a 12-inch PSA (pressure-sensitive adhesive) abrasive disc designed for stationary disc sanders and grinding applications requiring a very fine finish. Built on a heavyweight X-weight cloth backing, this disc delivers the flexibility and durability needed for contour sanding and flat surface finishing. The 240-grit aluminum oxide abrasive provides consistent stock removal at the very fine grade range, making it well-suited for final-pass surface prep, light material removal, and finish sanding on metal, wood, and composites. Licensed HVAC, mechanical, and fabrication shops working with sheet metal or duct components will find this disc appropriate for surface conditioning work prior to coating or assembly.

This disc is used in light fabrication, metalworking, woodworking, and surface preparation applications where a clean, refined surface finish is required before painting, coating, or bonding. The pressure-sensitive adhesive backing allows fast mounting and removal on compatible PSA disc sander platens. The flexible cloth construction conforms to slightly irregular surfaces, reducing the risk of gouging or uneven material removal. It is sold individually and is appropriate for both shop and field use where a stationary or portable disc sander with a 12-inch PSA platen is in use.

Installation Notes

Installation is performed by trade professionals in fabrication, metalworking, and woodworking environments. Before mounting, ensure the disc sander is powered off and unplugged or locked out per applicable safety procedures. Clean the platen surface of any adhesive residue from the previous disc before applying the new PSA disc to ensure full, even adhesion. Avoid touching the adhesive face with bare hands, as skin oils can reduce bond strength.
