3M 7100113080 Cubitron Ii Hookit Disc 947A 80 Grit 6 in

Product Description

The 3M 7100113080 is a Cubitron II Hookit cloth disc in the 947A series, designed for aggressive material removal on metal surfaces. It uses 3M Precision Shaped Grain technology bonded to an X-weight polyester-cotton cloth backing, delivering fast cut rates and extended disc life compared to conventional abrasive grain. A built-in grinding aid reduces heat buildup during use, making this disc well suited for medium to high pressure grinding applications. Licensed tradespeople and fabricators working in metal finishing, weld blending, and stock removal applications will find this disc a practical choice for sustained production work.

This disc is engineered for use on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys where heat control and cut consistency are critical. At 6 inches in diameter with an 80 grit rating, it fits standard 6-inch random orbital and disc grinders equipped with a Hookit hook-and-loop interface. It is well suited for shop fabrication environments, weld seam blending, and surface conditioning in aerospace, manufacturing, and structural metalwork settings.

Key Features

• Precision Shaped Grain delivers fast, consistent cut rates for higher productivity in metal grinding
• Hookit hook-and-loop attachment system allows quick disc changes and supports disc reuse
• X-weight polyester-cotton cloth backing withstands aggressive sanding and grinding pressure
• Grinding aid reduces heat generation and helps prevent workpiece discoloration
• Resin bond resists heat degradation to extend disc usable life
• 80 grit rating suitable for medium stock removal and weld blending on metal

Compatibility

Designed for use with 6-inch hook-and-loop (Hookit) disc grinders and random orbital sanders. Compatible with stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloy workpieces.

Installation Notes

This disc is installed and replaced by metalworking professionals and fabricators using standard 6-inch Hookit-compatible grinders. Ensure the tool is powered off and disconnected before changing discs. Inspect the backing pad for wear before attaching a new disc to ensure secure seating. Follow applicable ANSI and shop safety standards for abrasive wheel and disc use, including appropriate PPE for grinding operations.
