Norton 66261136614 Psa Disc 12 in 100 Grit Aluminum Oxide

Product Description

The NORTON 66261136614 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal and surface finishing on stationary and portable disc sanders. Built on an X-weight cloth backing, this disc delivers the rigidity needed for heavy stock removal while maintaining flexibility for contoured surfaces. The aluminum oxide abrasive is bonded to a brown cloth substrate and rated at 100 grit, placing it in the fine grade range for controlled surface preparation. At 12 inches in diameter, it is suited for large-format grinding and finishing applications common in metalworking, woodworking, and fabrication environments. Installed by machinists, fabricators, and finish carpenters, this disc mounts directly to PSA-compatible backup pads without fasteners or clips.

This disc is appropriate for use on stationary disc sanders and bench-mounted equipment configured for 12-inch PSA discs. It is well suited for surface leveling, weld blending, and pre-finishing operations on wood, metal, and composite materials in both production and job-shop settings. The fine 100 grit rating makes it appropriate for intermediate finishing passes where a smooth, refined surface is required before final finishing steps. No vacuum holes are included, making this disc compatible with solid backup pads rather than dust-collection perforated platens.

Key Features

• Aluminum oxide abrasive for consistent cut and long service life on wood and metal
• X-weight cloth backing provides strength and flexibility for demanding applications
• Pressure-sensitive adhesive backing for tool-free mounting to compatible PSA backup pads
• 100 grit fine grade for controlled stock removal and surface preparation
• 12-inch diameter fits large-format stationary disc sanders
• No vacuum holes — designed for solid platen backup pads

Compatibility

Designed as an OEM-style replacement disc for stationary disc sanders and bench sanders that accept 12-inch PSA-mount abrasive discs with solid backup platens.

Installation Notes

Installation is performed by machinists, woodworkers, or fabricators as routine consumable replacement. Power down and lock out the sander before removing the spent disc and cleaning adhesive residue from the backup pad. Peel the liner from the PSA backing and align the disc to the pad before pressing firmly from center outward to eliminate air pockets. Inspect the backup pad for flatness and adhesive contamination before mounting a new disc, as an uneven pad surface will cause premature disc failure.
