3M 7000118912 Psa Cloth Disc 348D 3/4 in P120 Grit Ao

Product Description

The 3M 7000118912 is a PSA cloth sanding disc in the 348D series, designed for aggressive material removal in industrial and trade finishing applications. Measuring 3/4 inch in diameter and carrying a P120 grit aluminum oxide abrasive, this disc is built for fast cutting and extended service life. The pressure-sensitive adhesive backing bonds securely to a backup pad or steel platen and releases cleanly for rapid disc changes. An X-weight cloth backing resists tearing and edge wear under demanding conditions, and a resin bond system protects the abrasive layer from heat degradation during prolonged use.

This disc suits metal fabrication, woodworking, and general surface preparation tasks where a small-diameter, high-speed abrasive is required. Rated to 20,000 RPM, it is appropriate for use on high-speed rotary tools and inline sanders. The aluminum oxide abrasive performs across ferrous metals, hardwood, and composite surfaces. The disc supports both wet and dry sanding operations, giving it flexibility across varied shop and field conditions. Technicians and fabricators handling detail work or tight geometries will find the 3/4 inch format useful for precision surface blending.

Key Features

• Pressure-sensitive adhesive backing adheres to backup pads or steel platens and allows fast, clean removal
• X-weight cloth backing resists tearing and edge wear in aggressive sanding applications
• Aluminum oxide abrasive delivers fast cutting and long service life across multiple surface types
• Resin bond construction reduces heat damage and extends disc life
• Compatible with wet and dry sanding applications
• Rated to 20,000 RPM for use with high-speed rotary tooling

Compatibility

Designed for use with backup pads or steel platens that accept 3/4 inch PSA-style sanding discs in rotary and inline sanding tools rated to 20,000 RPM or lower.

Installation Notes

Installation is performed by trade finishers, fabricators, and abrasives technicians. Ensure the backup pad or steel platen surface is clean and free of debris before applying the disc to achieve full adhesive contact. Confirm the tool speed rating does not exceed 20,000 RPM before operation. Worn or contaminated platens should be cleaned or replaced to maintain proper disc adhesion and prevent slippage during use.
