3M 7100113137 Cubitron Ii Hookit Disc 5 Inch 60 Grit

Product Description

The 3M 7100113137 is a coated abrasive disc built around 3M Precision Shaped Grain on an X-weight polyester-cotton cloth backing. This disc is rated at 60 grit and fits 5-inch hook-and-loop backup pads, running at a maximum of 12,000 RPM. A built-in grinding aid actively reduces heat buildup at the contact point, extending disc life and helping to prevent workpiece discoloration during medium to high pressure grinding. Resin bond material adds further heat resistance. The Hookit attachment system allows fast disc changes without tools, reducing downtime on the grinder.

This disc is designed for demanding material removal on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. It is well suited to weld grinding, stock removal, and blending operations in fabrication shops, maintenance facilities, and manufacturing environments. The X-weight cloth backing handles aggressive pressure without deformation, making it appropriate for production grinding where consistent cut rate matters across an extended run of parts.

Key Features

• 3M Precision Shaped Grain delivers fast, consistent cut rate on hard metals
• Hookit hook-and-loop attachment allows tool-free disc changes and disc reuse
• X-weight polyester-cotton cloth backing withstands aggressive grinding pressure
• Grinding aid reduces heat generation and helps prevent workpiece discoloration
• Resin bond resists heat degradation during extended high-pressure use
• 12,000 RPM maximum speed rating suits standard 5-inch angle grinders and sanders

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on angle grinders and random orbital sanders rated to 12,000 RPM or below. Suitable for grinding stainless steel, carbon steel, cobalt chrome, and nickel alloys.

Installation Notes

Mount to a clean, undamaged 5-inch Hookit backup pad, ensuring the hook-and-loop interface seats fully before operation. Verify the tool spindle speed does not exceed the 12,000 RPM disc rating before starting. Wear appropriate PPE including face shield and gloves when grinding exotic alloys. Inspect the disc for cuts, tears, or delamination before each use and remove from service if damage is found.
