Norton 66261125444 Hook Loop Disc 80 Grit 5 Inch

Product Description

The NORTON 66261125444 is a 5-inch hook and loop abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Built on an E-weight paper backing, this coated disc uses zirconia alumina grain to deliver consistent cut rates and extended service life compared to standard aluminum oxide options. At 80 grit, it falls in the medium grade range, making it well suited for blending welds, removing rust, and leveling surface irregularities before finishing. The flexible paper backing conforms to slightly contoured work surfaces, reducing gouging on edges and corners. This is a production-grade disc intended for use by fabricators, pipefitters, and finish tradespeople working with random orbital or disc sanders.

This disc is sized for 5-inch random orbital sanders and disc sanders equipped with hook and loop backing pads. It is commonly used in metal fabrication shops, HVAC sheet metal work, plumbing rough-in prep, and general-purpose surface conditioning. The absence of vacuum holes makes it a straightforward drop-in for standard non-perforated hook and loop pads. It is sold individually but requires a minimum order of 25 units, making it practical for stocking shop consumables. The zirconia alumina abrasive is particularly effective on stainless steel, mild steel, and hard woods where heat buildup can prematurely dull conventional abrasives.

Key Features

• Zirconia alumina abrasive grain for high cut rate and long disc life on metal and hard surfaces
• E-weight paper backing provides flexibility for light contouring while maintaining stability under load
• Hook and loop attachment for fast disc changes on compatible sanders
• 80 grit medium grade suited for material removal, weld blending, and surface prep before finishing
• No vacuum holes for use with solid hook and loop backing pads
• Part of the NORTON H875 series for consistent performance across production environments

Compatibility

Designed for use with 5-inch hook and loop backing pads on random orbital and disc sanders without vacuum hole patterns. Compatible with standard hook and loop pad configurations used in metal fabrication, woodworking, and general surface preparation applications.

Installation Notes

Disc installation and removal does not require tools — press firmly onto the hook and loop backing pad to seat, and peel off to remove. Ensure the sander is powered off and disconnected before changing discs. Inspect the backing pad regularly for worn hook material, as a degraded pad will reduce disc retention and can cause the disc to detach during use. Discs should be stored flat in a dry environment to prevent moisture absorption into the paper backing, which can reduce abrasive performance.
