Norton 662611-31507 Sanding Disc 6 in P320B Grit A275 6 Pack

Product Description

The NORTON 662611-31507 is a pressure-sensitive adhesive (PSA) sanding disc designed for surface preparation and finishing applications. Part of the A275 series, this disc measures 6 inches in diameter and features a P320B grit rating, placing it in the fine-finishing range. The 6-hole vacuum pattern supports dust extraction during use, keeping the work surface cleaner and extending disc life. These discs are sold in a roll pack of 6 and are suited for use by automotive body technicians, woodworkers, and finishing contractors who require consistent cut and finish on a production basis.

This disc is applicable to flat and contoured surface sanding on wood, painted surfaces, primers, and composite materials. The A275 designation identifies a multi-purpose aluminum oxide abrasive construction suited for both hand-applied orbital sanders and random-orbit tools equipped with PSA backing pads. The 6-vacuum-hole configuration aligns with standard 6-inch PSA sanding pad layouts common on production finishing equipment. The P320B grit level is appropriate for final surface leveling, scuff sanding, and pre-topcoat preparation work.

Key Features

• P320B fine grit for final surface leveling and pre-topcoat scuff sanding
• 6-inch diameter PSA backing for direct adhesion to hook-free sanding pads
• 6-hole vacuum port pattern for dust extraction compatibility
• A275 aluminum oxide abrasive construction for consistent cut rate
• Sold in a roll pack of 6 discs for production workflow efficiency

Compatibility

Designed for use with 6-inch PSA-style sanding pads on random-orbit and orbital finishing sanders equipped with vacuum dust extraction ports.

Installation Notes

Peel the release liner from the PSA backing and press firmly onto a clean, dry sanding pad to ensure full adhesion before use. Ensure the vacuum holes on the disc align with the ports on the sanding pad for proper dust extraction. Replace the disc when abrasive loading or glazing reduces cut efficiency. Dispose of used discs in accordance with local waste regulations if used on coatings containing hazardous materials.
