Norton 66261136350 Psa Disc 36 Grit 8 in Aluminum Oxide

Product Description

The NORTON 66261136350 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal in industrial and trade grinding applications. Built on an X-weight cloth backing, this disc delivers the rigidity needed for heavy stock removal on metal, wood, and composite surfaces. At 36 grit, it falls in the very coarse grade range, making it the right choice for initial shaping, weld blending, and surface leveling before finer finishing passes. The aluminum oxide abrasive grain is a durable, versatile cutting media well-suited to sustained use under high pressure and heat. This disc is part of the Norton R228 series.

This disc is suited for use in fabrication shops, metalworking operations, woodworking production lines, and general industrial surface preparation. The PSA mount attaches directly to a compatible foam pad or backup pad on stationary and portable disc sanders. The 8-inch diameter fits standard backup pads common in both shop and field applications. No vacuum holes are present, making this disc appropriate for use on solid backup pads where dust collection is handled separately. The flexible construction allows the disc to conform slightly to irregular surfaces.

Key Features

• X-weight cloth backing provides durability and resistance to tearing under load
• Pressure-sensitive adhesive mount for fast, secure attachment to compatible backup pads
• Flexible disc construction for improved contact on uneven surfaces
• No vacuum holes for use with solid backup pads
• Part of the Norton R228 series

Compatibility

Designed for use with 8-inch PSA backup pads on disc sanders and similar abrasive equipment used in metalworking, woodworking, and industrial surface preparation.

Installation Notes

Installation is performed by pressing the PSA-backed disc firmly onto a clean, dry, compatible backup pad, ensuring full surface contact to prevent edge lift during operation. Ensure the sander or grinder is powered off and unplugged before mounting or removing a disc. Inspect the backup pad for wear or damage before each use, as a compromised pad can cause uneven abrasive wear or disc separation. Follow applicable ANSI and OSHA abrasive wheel safety guidelines, including the use of appropriate eye and face protection.
