3M 7100113107 Abrasive Cloth Disc 80 Grit 6 Inch

Product Description

The 3M 7100113107 is a Cubitron II Hookit abrasive cloth disc engineered for demanding metal grinding and finishing applications. Built on an X-weight polyester-cotton cloth backing, this disc uses 3M Precision Shaped Grain technology to deliver consistently fast cut rates across a wide range of metallic materials. A built-in grinding aid reduces heat buildup at the work surface, helping to prevent workpiece discoloration and extend disc life. Resin bonding further resists heat degradation during aggressive, high-pressure passes. The disc measures 6 inches in diameter and is rated to 12,000 RPM. It is well suited for fabricators, welders, and metalworking professionals who require reliable, repeatable stock removal.

This disc is designed for medium to high pressure grinding and finishing on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. The Hookit attachment system allows fast disc changes without tools, making it practical in production environments where multiple grits or disc types are rotated throughout a shift. At 80 grit, the disc provides aggressive cut suitable for weld blending, deburring, and surface conditioning prior to finer finishing steps.

Key Features

• Precision Shaped Grain delivers fast, consistent cut rates for improved productivity
• Hookit attachment allows quick tool-free disc changes and disc reuse
• X-weight polyester-cotton cloth backing withstands aggressive sanding and grinding pressure
• Integrated grinding aid reduces heat and helps prevent surface discoloration on alloys
• Resin bond system resists heat degradation during sustained high-pressure use
• Rated to 12,000 RPM for compatibility with standard angle grinders and disc sanders

Compatibility

Designed for use with Hookit-compatible random orbital sanders, disc grinders, and right-angle grinders that accept 6-inch hook-and-loop abrasive discs.

Installation Notes

Installation is performed by metalworking fabricators and finishing technicians. Verify the tool spindle speed does not exceed the 12,000 RPM disc rating before mounting. Ensure the Hookit backing plate is clean and free of debris to maintain secure disc attachment. Always wear appropriate PPE including eye protection and gloves when operating grinding and finishing equipment.
