Norton 662611-31624 Abrasive Sheet P400B 9x11 in 100 Sheets

Product Description

The NORTON 662611-31624 is a premium coated abrasive sheet designed for fine finishing work across a range of sanding applications. Built on a B-weight anti-loading paper backing, this sheet uses aluminum oxide as its cutting mineral, delivering consistent scratch patterns and extended sheet life. The P400B grit rating places it in the super fine range, making it well suited for final surface prep, sealer sanding, and between-coat finishing on wood, metal, and painted surfaces. Each sheet measures 9 inches x 11 inches and is packaged in counts of 100 sheets per pack.

These sheets are commonly used in wood finishing shops, body shops, cabinet shops, and general manufacturing environments where controlled, fine-grit material removal is required. The No-Fil Adalox design incorporates an anti-loading coating that resists clogging when working with resins, sealers, and softwoods. The A275OP type designation identifies this as an open-coat construction, which further reduces loading during use. Hand sanding and orbital finishing applications are both supported by the 9 x 11 inch standard sheet format.

Installation Notes

These sheets are installed by hand or fitted to a sanding block and require no tools beyond standard cutting equipment to trim to size. Always sand with a clean, dry surface to maximize sheet life and reduce premature loading. Wear appropriate respiratory protection when dry sanding to comply with applicable workplace safety standards. Inspect sheets regularly and replace when cutting action degrades or loading becomes excessive.
