Norton 662611-31509 Sanding Disc 6 in A275 P240B Grit

Product Description

The NORTON 662611-31509 is a pressure-sensitive adhesive sanding disc designed for orbital and random-orbit sanders used in woodworking, automotive bodywork, and surface preparation applications. Built on the A275 backing, this disc delivers consistent cut and finish performance across a range of substrates including wood, paint, primer, and composite materials. The P240B grit rating places it in the fine-finishing range, making it well suited for final material removal passes and surface smoothing before topcoat application. These discs are sold in bulk rolls and are intended for professional finishing trades requiring high-volume consumable stock.

This disc is designed for use in production finishing environments such as cabinet shops, body shops, and on-site carpentry. The 6-inch diameter with a 6-hole vacuum pattern pairs with standard 6-inch hook-and-loop or PSA-compatible random-orbit sanders equipped for dust extraction. The A275 series is a general-purpose aluminum oxide abrasive product appropriate for both light-duty and production-level sanding tasks. Packaging quantity is 6 discs per unit, with a minimum order quantity of 100 units per purchase.

Key Features

• A275 aluminum oxide abrasive construction for consistent cut across wood, paint, and primer
• P240B grit for fine finishing and pre-topcoat surface smoothing
• 6-inch diameter with 6-hole vacuum pattern for dust extraction compatibility
• Pressure-sensitive adhesive backing for secure mounting to PSA sanding pads
• Bulk roll format supports high-volume production use
• 6 discs per package unit

Compatibility

Designed for use with 6-inch PSA-style random-orbit sanders equipped with a 6-hole dust extraction pad. Confirm pad type and hole pattern before installation.

Installation Notes

These discs are installed by pressing the PSA backing firmly onto a clean, dry sanding pad. Ensure the existing disc is fully removed and the pad surface is free of adhesive residue before applying a new disc. Misaligned vacuum holes will reduce dust extraction efficiency and shorten disc life. Discs should be replaced when abrasive loading or glazing reduces cut rate noticeably.
