Norton 66261183807 Psa Disc 100 Grit 5 Inches Aluminum Oxide

Product Description

The NORTON 66261183807 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for surface finishing and material removal in professional shop and field environments. Constructed with an aluminum oxide abrasive bonded to a B-weight paper backing, this disc delivers consistent cut at 100 grit across a 5-inch diameter working surface. The flexible backing conforms to slight surface contours, helping maintain even scratch patterns. The PSA mount eliminates the need for hook-and-loop fasteners, providing a firm, vibration-resistant bond to compatible backup pads. Each package contains 100 discs from the Norton A296 series.

This disc is rated for use on random orbital sanders operating up to 15,000 RPM. It is suited for wood, composites, painted surfaces, and similar substrates where a fine-grade cut is required. The yellow paper backing and vacuum-hole-free design make it a straightforward choice for finishing passes where dust extraction is handled through shroud or external collection rather than through-pad suction. Tradespeople, woodworkers, and finishing contractors working in production or repair environments will find the 100-disc count practical for high-volume jobs.

Key Features

• 100 grit aluminum oxide abrasive for fine-grade material removal and surface prep
• 5-inch diameter PSA backing for secure, low-vibration adhesive mount to backup pads
• B-weight paper backing provides flexibility for slight surface contouring
• Rated to 15,000 RPM for compatibility with standard random orbital sanders
• No vacuum holes — suited for shroud or external dust collection setups
• 100 discs per package for high-volume production use

Compatibility

Compatible with random orbital sanders accepting 5-inch PSA backup pads rated to 15,000 RPM. No vacuum holes are present, so this disc is not compatible with through-pad dust collection systems.

Installation Notes

Ensure the sander is powered off and unplugged before mounting or removing discs. Align the disc squarely on the backup pad and press firmly from the center outward to seat the adhesive evenly and prevent edge lifting. Do not exceed the 15,000 RPM maximum speed rating. Discard discs showing signs of loading, tearing, or adhesive failure.
