Norton 66254461510 Psa Disc 5 in 80 Grit Ceramic

Product Description

The NORTON 66254461510 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Part of the R980P series, it uses a ceramic abrasive grain bonded to a Y-weight cloth backing, which provides the rigidity and durability needed for high-pressure grinding and finishing applications. The 5-inch diameter and 80-grit cut make it well suited for blending welds, shaping stock, and prepping surfaces before finer finishing steps. Licensed tradespeople and fabricators rely on this disc type for consistent stock removal rates and long service life compared to aluminum oxide alternatives.

This disc is used in industrial and trade environments including metal fabrication shops, automotive body work, woodworking, and general surface preparation. The PSA mount attaches directly to a foam or hard rubber backup pad on a random orbital or disc sander without the need for hook-and-loop hardware. The Y-weight cloth backing handles demanding applications where paper-backed discs would tear or delaminate under load. No vacuum holes are included, so it is paired with solid backup pads rather than dust-collection setups requiring perforated patterns.

Key Features

• Ceramic abrasive grain for fast, consistent stock removal and extended disc life
• Y-weight cloth backing resists tearing and flexing under high-pressure grinding
• 80-grit provides aggressive material removal suitable for blending, shaping, and surface prep
• PSA adhesive mount for quick, secure attachment to compatible backup pads
• Orange disc color for easy grit identification on the shop floor
• No vacuum holes — designed for use with solid backup pads

Compatibility

Designed as an OEM-style replacement PSA abrasive disc for use with 5-inch solid backup pads on random orbital sanders and disc grinders commonly used in metal fabrication, automotive, and woodworking applications.

Installation Notes

Installation is performed by tradespeople using disc sanders or angle grinders fitted with a compatible 5-inch PSA backup pad. Ensure the sander is powered off and unplugged before mounting or removing discs. Clean the backup pad surface of any adhesive residue before applying a new disc to ensure a secure bond. Do not exceed the maximum RPM rating of the backup pad or sander when operating.
