Norton 66261136662 Psa Disc 15 Inch 80 Grit Aluminum Oxide

Product Description

The NORTON 66261136662 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large flat or contoured surfaces. Built on an X-weight cloth backing, this disc delivers the rigidity and durability needed for demanding grinding and finishing applications. The 80-grit aluminum oxide abrasive cuts efficiently through metal, wood, composites, and painted surfaces. At 15 inches in diameter, it is sized for large floor sanders, wide-belt-style machines, and industrial finishing equipment. The flexible cloth construction conforms to slight surface irregularities while maintaining consistent grit contact across the full disc face.

This disc is suited for industrial and commercial finishing environments where high material removal rates are required before moving to finer grits. Typical applications include floor sanding, metal fabrication prep work, and surface conditioning on large panels or structural components. It is commonly installed by floor finishing contractors, fabrication shop technicians, and maintenance professionals working with wide-format disc sanding equipment. The PSA mount provides a clean, tool-free attachment to compatible foam or rubber backup pads.

Key Features

• 80-grit aluminum oxide abrasive for efficient stock removal on metal, wood, and composites
• X-weight cloth backing provides added stiffness and tear resistance under load
• Pressure-sensitive adhesive backing for fast, tool-free disc changes
• 15-inch diameter sized for large-format floor and industrial disc sanders
• Flexible construction allows conformance to slight surface contours
• No vacuum holes — designed for use on solid backup pads

Compatibility

Designed as a PSA-mount replacement disc for large-format disc sanders and floor finishing machines that accept 15-inch pressure-sensitive adhesive abrasive discs with solid backup pads.

Installation Notes

Installation is performed by finishing contractors or fabrication technicians familiar with large-format abrasive equipment. Power down and disconnect the sanding machine before removing or installing any disc. Ensure the backup pad surface is clean and free of adhesive residue before applying the new disc to achieve full contact and prevent premature release during operation. Do not exceed the maximum RPM rating of the sanding machine or backup pad in use.
