Norton 66261136666 Psa Disc 15 in 36 Grit Aluminum Oxide

Product Description

The NORTON 66261136666 is a 15-inch PSA (pressure-sensitive adhesive) abrasive disc built for heavy material removal on large flat or contoured surfaces. It uses aluminum oxide grain bonded to an X-weight cloth backing, which provides the rigidity and durability needed for aggressive stock removal applications. At 36 grit, this disc falls in the very coarse grade range, making it well-suited for initial shaping, weld grinding, and surface prep work where speed of cut matters more than finish. The flexible cloth construction allows it to conform slightly to irregular workpiece geometry without breaking down prematurely. Weight is 0.5 pounds per disc.

This PSA disc is used in industrial, fabrication, and woodworking environments where large-diameter grinding or sanding is performed on stationary or floor-mounted disc sanders. The pressure-sensitive adhesive backing allows fast, tool-free mounting to compatible foam or rubber backup pads. It is well-suited for tasks such as weld seam blending, paint and rust removal, and aggressive surface preparation on metal, wood, or composite materials. Tradespeople, fabricators, and production shop operators working with large-format sanders are the primary installers and end users of this disc.

Key Features

• 15-inch diameter fits large-format PSA disc sanders and backup pads
• 36 grit very coarse aluminum oxide grain for aggressive stock removal
• X-weight cloth backing delivers durability under high pressure and heat
• Flexible construction allows partial conformance to curved or irregular surfaces
• Pressure-sensitive adhesive backing for fast, tool-free pad mounting
• No vacuum holes — suited for solid backup pad configurations

Compatibility

Designed for use with 15-inch PSA-style backup pads and disc sanders that accept pressure-sensitive adhesive abrasive discs without vacuum holes.

Installation Notes

This disc is installed by a fabricator or machine operator and does not require hand tools — peel the liner and press firmly onto a clean, dry PSA backup pad. Ensure the sanding machine is fully powered off and unplugged before changing discs. Verify that the backup pad diameter matches the disc diameter to prevent edge lifting or uneven wear. Discard discs that show glazing, tearing, or delamination of the cloth backing.
