Norton 662611-33338 Waterproof Paper Disc 12 in T461 240 Grit

Product Description

The NORTON 662611-33338 is a 12-inch waterproof paper abrasive disc designed for wet and dry sanding applications in trade and industrial environments. Supplied in bulk packaging of 50 discs per unit, this T461-type disc runs at 240 grit, making it suitable for fine material removal, surface prep, and finish sanding on wood, metal, composites, and painted surfaces. The waterproof paper backing resists moisture breakdown during wet sanding, extending disc life and maintaining consistent cut. Finishing tradespeople, woodworkers, auto body technicians, and industrial fabricators are the primary users of this disc format.

This disc is used in applications requiring controlled stock removal with a fine finish pass. The no-hole configuration suits orbital and rotary sanders with non-vacuum backing plates. At 12 inches in diameter, it fits large-format sanders and floor machines commonly used in commercial finishing, production shops, and refinishing operations. Wet sanding use cases include paint blending, lacquer flatting, and composite surface leveling where heat and loading are concerns.

Compatibility

Designed as an OEM-style replacement disc for 12-inch rotary and orbital sanders using no-hole backing plates in wet or dry sanding configurations.

Installation Notes

Attachment method varies by backing plate type — confirm the sander accepts 12-inch no-hole discs before use. Secure the disc firmly to the backing plate to prevent slippage during operation. When wet sanding, ensure the sander and any electrical components are rated for wet conditions per applicable safety codes. Inspect each disc for tears or backing delamination before mounting.
