Norton 66261149873 Psa Disc 60 Grit Ceramic 5 Inches

Product Description

The NORTON 66261149873 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive stock removal on metal, wood, and composite surfaces. Part of the H920 Series, this disc features a ceramic abrasive grain on an F-weight paper backing, delivering consistent cut rate and durability across high-pressure grinding and sanding applications. At 60 grit, it falls in the medium-to-coarse cutting range, making it well suited for weld blending, surface prep, and rapid material removal. The flexible paper backing conforms to slightly contoured surfaces, reducing gouging. Each package contains 100 discs measuring 5 inches in diameter. No vacuum holes are included. The PSA mount attaches directly to a compatible foam or rubber backup pad.

This disc is used in industrial maintenance, metal fabrication, woodworking shops, and field surface preparation. The H920 Series ceramic grain is engineered to fracture during use, continuously exposing sharp cutting edges to extend disc life compared to aluminum oxide alternatives. Typical applications include weld seam grinding, rust removal, paint stripping, and dimensional blending on flat or near-flat workpieces. The maroon disc color aids in visual identification on the shop floor. Installation requires a 5-inch PSA backup pad; no fasteners or lock nuts are needed.

Key Features

• Ceramic abrasive grain for extended cut life and self-sharpening action during use
• F-weight paper backing provides flexibility for contoured surface contact
• PSA mount for fast, tool-free disc changes on compatible backup pads
• 60 grit for aggressive stock removal, weld blending, and surface prep
• No vacuum holes — suited for solid backup pads without dust extraction ports
• 100 discs per package for high-volume production use

Compatibility

Designed for use with 5-inch PSA (adhesive) backup pads on angle grinders, random orbital sanders, and disc sanders configured for PSA-mount abrasives. No vacuum hole pattern; confirm backup pad type before ordering.

Installation Notes

Power down and unplug or de-energize the tool before changing discs. Peel the release liner from the PSA backing and press the disc firmly onto a clean, dry backup pad to ensure full adhesive contact. Inspect the backup pad for wear or contamination that could cause the disc to release during operation. Follow ANSI B7.1 and tool manufacturer guidelines for maximum operating speed.
