Norton 66261136710 Psa Disc 20in 36 Grit Aluminum Oxide

Product Description

The NORTON 66261136710 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large flat surface applications. Built on an X-weighted cloth backing, this disc delivers the rigidity and durability needed for heavy stock removal without premature breakdown. At 20 inches in diameter and 36 grit, it falls in the very coarse grade range, making it well suited for rapid surface preparation, weld blending, paint stripping, and rough shaping on metal, wood, or composite substrates. The aluminum oxide abrasive mineral is a workhorse grain that self-sharpens under pressure and holds up through demanding production cycles. This disc is part of the Norton R228 series and ships as a single disc per package.

This disc is used in industrial finishing, fabrication shops, and flooring operations where large-diameter PSA disc machines are standard equipment. The 20-inch size fits disc sanders and floor machines configured for that platen diameter. The very coarse 36-grit cut rate is appropriate for first-pass operations where the goal is fast material removal rather than surface refinement. The flexible cloth construction allows the disc to conform slightly to minor surface irregularities, maintaining consistent abrasive contact across the full disc face. No vacuum holes are present, making this disc compatible with solid-platen machines only.

Key Features

• 20-inch diameter PSA disc fits large-format disc sanders and floor machines with solid platens
• 36 grit very coarse aluminum oxide for fast, aggressive stock removal
• X-weighted cloth backing provides superior tear resistance and rigidity under load
• Flexible construction maintains abrasive contact across the full disc surface
• Pressure-sensitive adhesive mount for quick disc changes without mechanical fasteners
• No vacuum holes — designed for use with solid-platen machines only

Compatibility

Designed for use with large-format PSA disc sanders and floor machines that accept a 20-inch solid-platen disc. No specific model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Ensure the machine platen is clean, dry, and free of adhesive residue from previous discs before applying this PSA disc. Press the disc firmly from center to edge to eliminate air pockets and ensure full adhesive contact. Power down and disconnect the machine from its power source before mounting or removing any abrasive disc. Worn or glazed discs should be replaced promptly to prevent heat buildup and uneven surface results.
