3M 7010299963 Psa Cloth Disc 348D 15 Inch 36 Grit Ao

Product Description

The 3M 7010299963 is a PSA cloth sanding disc in the 348D series, designed for heavy-duty material removal on flat and contoured surfaces. It uses a pressure-sensitive adhesive backing that bonds securely to backup pads or steel platens and releases cleanly for fast disc changes. The abrasive mineral is aluminum oxide, a durable, fast-cutting grain suited to a wide range of ferrous and non-ferrous substrates. At 36 grit, this disc targets aggressive stock removal applications. An X-weight cloth backing and resin bond give the disc the structural strength and heat resistance needed for sustained, high-load grinding and sanding cycles.

This disc is sized at 15 inches in diameter and is well-suited for large-area surface preparation work in metal fabrication shops, industrial finishing lines, and heavy equipment maintenance environments. It handles both wet and dry sanding conditions, making it adaptable to different process requirements. Trades that commonly use this disc include metalworkers, weld finishers, and industrial maintenance technicians working with stationary or portable disc sanders equipped with compatible backup pads or steel platens.

Key Features

• Pressure-sensitive adhesive backing bonds to backup pads or steel platens and releases cleanly for fast replacement
• X-weight cloth backing resists tearing and edge wear under aggressive load conditions
• Aluminum oxide abrasive delivers fast cutting action and extended service life across a wide range of surfaces
• Resin bond construction dissipates heat to protect disc integrity during prolonged use
• Rated for both wet and dry sanding applications
• 15 inch diameter suits large flat-surface material removal tasks

Compatibility

Designed for use with backup pads or steel platens that accept 15 inch PSA-mount sanding discs on disc sanders and surface grinders configured for that platen size.

Installation Notes

Power down and lock out the sanding machine before mounting or removing the disc. Ensure the backup pad or steel platen surface is clean and free of adhesive residue before applying a new disc to achieve full PSA contact. This product is typically installed and serviced by metalworking or industrial maintenance personnel familiar with abrasive equipment. Follow the equipment manufacturer's recommended operating speed and do not exceed the disc's rated RPM.
