Norton 66261055018 Hook Loop Disc 80 Grit 4 Inch

Product Description

The NORTON 66261055018 is a 4-inch hook and loop abrasive disc designed for surface preparation, blending, and finishing work across metal, wood, and composite substrates. Built with aluminum oxide abrasive on a flexible non-woven backing, this medium-grade 80-grit disc delivers consistent cut and surface texture. The hook and loop attachment system allows fast disc changes without tools, making it a practical choice for production environments and field service work. At 0.03 pounds, the disc is lightweight and compatible with standard random orbital and right-angle sanders equipped with hook and loop pads.

This disc is suited for deburring, light material removal, and surface conditioning tasks in metal fabrication, HVAC sheet metal work, plumbing rough-in, and general construction finishing. The flexible non-woven construction conforms to irregular surfaces and contoured workpieces, making it effective where rigid discs lose contact. It is commonly used by tradespeople who need a consistent medium-grit finish before priming, coating, or final assembly. No vacuum holes are included, so it is intended for use on non-vac orbital sanders or angle grinders with a compatible backing pad.

Key Features

• 80-grit medium-grade aluminum oxide abrasive for controlled material removal and surface blending
• Flexible non-woven construction conforms to curved and irregular surfaces
• Hook and loop backing enables tool-free disc swaps during high-volume work
• 4-inch diameter fits standard hook and loop orbital and angle sander pads
• No vacuum holes — designed for solid-pad backing plate use
• Lightweight at 0.03 pounds for reduced operator fatigue during extended use

Compatibility

Designed as an OEM-style replacement or standard consumable for 4-inch hook and loop random orbital sanders and angle grinders equipped with a compatible hook and loop backing pad. No vacuum-hole alignment required.

Installation Notes

This disc is installed by pressing the loop side firmly onto a 4-inch hook-style backing pad mounted to a sander or grinder. Ensure the backing pad is free of debris before seating the disc to maintain secure attachment. Inspect the disc for tears or loading before each use and replace if the abrasive shows uneven wear. Follow tool manufacturer guidelines for maximum RPM ratings to avoid disc separation at speed.
