Norton 66261136663 Psa Disc 15 in 60 Grit Aluminum Oxide

Product Description

The NORTON 66261136663 is a 15-inch pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive stock removal on large flat surfaces. Built on an X-weight cloth backing, it delivers the rigidity and durability needed for heavy-duty grinding and sanding applications. The aluminum oxide abrasive grain runs at 60 grit, a coarse-to-medium cut suited for rapid material removal, surface leveling, and weld blending. The PSA mount system allows fast disc changes without mechanical fasteners, keeping downtime low on production floor and jobsite work. This disc weighs 0.3 pounds and is part of the Norton R228 series.

This disc is intended for use on stationary or portable disc sanders with 15-inch PSA platens. Typical applications include metal fabrication shops, woodworking operations, and industrial finishing lines where large surface area and consistent cut rate matter. It is well suited for grinding welds, smoothing rough lumber, leveling substrate, and preparing surfaces prior to finishing coats. The flexible cloth backing conforms slightly to workpiece contours, making it useful on surfaces that are not perfectly flat. No vacuum holes are included, so it pairs with solid-platen machines rather than dust-extraction platens.

Key Features

• 60-grit aluminum oxide abrasive for aggressive stock removal and surface leveling
• X-weight cloth backing provides stiffness and tear resistance under load
• Flexible construction allows slight conformance to contoured workpiece surfaces
• No vacuum holes — designed for solid-platen disc sanders
• Part of the Norton R228 series for consistent performance across the product line

Compatibility

Designed as a direct-fit PSA replacement disc for 15-inch solid-platen disc sanders used in metal fabrication, woodworking, and industrial surface preparation.

Installation Notes

Installation is performed by qualified machine operators or maintenance technicians familiar with stationary abrasive equipment. Power down and lock out the machine before removing the spent disc. Clean the platen surface of adhesive residue before applying the new disc to ensure full, even contact and prevent premature edge lifting. Inspect the platen for damage or runout before use, as an uneven platen surface will reduce disc life and cut consistency.
