3M 7000120702 Clean and Strip Disc 4 in Silicon Carbide

Product Description

The 3M 7000120702 is a Scotch-Brite Clean and Strip Disc designed for aggressive surface preparation on metal and other substrates. Built around an extra coarse silicon carbide abrasive, it cuts through rust, paint, sealants, and surface coatings quickly and consistently. The disc includes a built-in 1/4 inch spindle that mounts directly to a die grinder or comparable portable rotary tool, eliminating the need for a separate arbor. At 0.16 pounds, it is lightweight and easy to handle during extended work. Trade professionals use this disc when wire brushes lack the cutting aggression needed for heavily coated or corroded surfaces.

This disc is suited for metal cleaning, coating removal, and surface prep tasks in fabrication shops, maintenance facilities, and field service environments. It is commonly used by welders, pipefitters, and industrial maintenance technicians preparing surfaces before welding, painting, or resealing. The 4 inch diameter fits standard die grinder tooling used in both commercial and light industrial applications. Its load and heat resistance allows prolonged use without significant degradation in cutting performance.

Key Features

• Extra coarse silicon carbide abrasive removes rust, paint, sealant, and coatings aggressively
• Built-in 1/4 inch spindle attaches directly to a die grinder or portable rotary tool
• Load and heat resistance maintains consistent cutting performance throughout disc life
• Effective alternative to wire brushes for surface stripping tasks
• Leaves a relatively fine finish despite aggressive material removal

Compatibility

Designed for use with die grinders and portable rotary tools accepting a 1/4 inch spindle arbor. Suitable for metal surface preparation including steel and other common fabrication substrates.

Installation Notes

Installation and use should be performed by a qualified technician familiar with rotary abrasive tooling. Verify the die grinder RPM rating meets or exceeds the disc RPM rating before mounting. Ensure the spindle is fully seated and secure before operating. Always wear appropriate eye and face protection when using abrasive discs, and inspect the disc for damage before each use.
