Norton 66623325941 Hook Loop Disc 5 in 320 Grit Aluminum Oxide

Product Description

The NORTON 66623325941 is a 5-inch hook-and-loop abrasive disc designed for surface finishing and prep work on a wide range of materials. Constructed with a non-woven aluminum oxide abrasive in an extra fine 320 grit, this disc delivers consistent scratch patterns and smooth finishes during final-stage sanding and surface conditioning. The flexible non-woven construction conforms to contoured surfaces, making it well-suited for detail work and finishing passes. It attaches via hook-and-loop backing for fast disc changes on compatible random orbital and disc sanders. This disc is sold individually and weighs 0.08 pounds.

This disc is used in finishing applications across trades including HVAC, plumbing, and general metalwork where surface prep before coating, sealing, or joining is required. The 320 grit extra fine grade is appropriate for light material removal, deburring, and scuff-sanding between coats. The non-woven construction resists loading and maintains cut consistency longer than coated abrasive alternatives in comparable grit ranges. It is suitable for use on metal, painted surfaces, wood, and composite materials in both shop and field settings.

Key Features

• 320 grit extra fine grade for finish sanding and surface conditioning
• Non-woven aluminum oxide construction resists loading and conforms to contours
• 5-inch diameter with hook-and-loop backing for tool-free disc changes
• Flexible disc body conforms to curved and irregular surfaces
• No vacuum holes — suitable for sanders without dust extraction ports

Compatibility

Designed for use with 5-inch hook-and-loop random orbital and disc sanders. No vacuum hole pattern, so it is intended for use with sanders that do not require hole-aligned dust collection.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc to maintain full hook-and-loop contact. Inspect the disc for tears or worn abrasive before use and replace if the abrasive surface is depleted. Operate within the sander manufacturer's rated speed for 5-inch discs. Wear appropriate eye protection and respiratory protection when sanding metal, painted surfaces, or composites.
