3M 7100113096 Cubitron Ii Hookit Disc 5 Inch 60 Grit

Product Description

The 3M 7100113096 is a Cubitron II Hookit Cloth Disc 947A designed for fast, aggressive stock removal on metal surfaces. It uses 3M Precision Shaped Grain, a triangular ceramic abrasive that fractures along consistent edges to maintain sharp cutting points throughout the life of the disc. The X-weight polyester-cotton cloth backing handles high-pressure grinding without tearing or distorting. A built-in grinding aid reduces friction heat at the workpiece surface, which is critical when working with heat-sensitive alloys. This disc is rated to 12000 RPM and is sized at 5 inches in diameter with a 60 grit cut.

This disc is suited for medium to high pressure grinding applications in fabrication shops, weld prep operations, and finishing lines where surface integrity matters. It performs on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys where heat buildup and discoloration must be minimized. The Hookit attachment system allows fast disc changes without tools, reducing downtime during production runs. Metal fabricators, aerospace technicians, and industrial grinders are the primary users of this product.

Key Features

• Precision Shaped Grain maintains sharp cutting edges through the disc life, increasing cut rate and productivity
• Hookit hook-and-loop attachment system enables quick, tool-free disc changes and allows disc reuse
• X-weight polyester-cotton cloth backing withstands aggressive grinding pressure without breakdown
• Grinding aid reduces heat generation at the workpiece, protecting heat-sensitive alloys from discoloration
• Resin bond system resists heat buildup to extend disc life under sustained load
• 60 grit cut rated for medium to aggressive stock removal on ferrous and non-ferrous metals

Compatibility

Designed for use with 5 inch Hookit-compatible random orbital sanders and angle grinders equipped with a hook-and-loop backup pad. Suitable for stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys.

Installation Notes

Verify that the grinder or sander is rated for at least 12000 RPM before mounting this disc. Confirm the backup pad uses a hook-and-loop interface compatible with the Hookit system. Power down and disconnect the tool from its power source before attaching or removing the disc. Inspect the disc for damage before each use and do not use a disc that shows tears, cuts, or separation of the backing.
