3M 7100284514 Stikit Cloth Disc 150 Plus 5 Inches 900DZ

Product Description

The 3M 7100284514 is a Cubitron II Stikit Cloth Disc designed for aggressive material removal on metal, composites, and other demanding substrates. Built on a J-weight cloth backing, this disc delivers flexibility and conformability across contoured surfaces while maintaining durability under sustained load. The 150 plus grit designation reflects a precision-shaped abrasive grain engineered to cut faster and last longer than conventional aluminum oxide abrasive discs. The open-coat construction minimizes loading, making it well suited for applications where swarf buildup would otherwise reduce cut rate. Resin bonding secures the grain through heavy stock removal cycles. The disc measures 5 inches in diameter with an NH center hole configuration (Die 500X) and attaches via the Stikit pressure-sensitive adhesive system for quick disc changes.

This disc is intended for use with 5-inch Stikit-compatible random orbital or disc sanders common in metal fabrication shops, automotive body work, aerospace component finishing, and industrial maintenance environments. The 900DZ series and open-coat resin bond make it a practical choice for grinding welds, blending surfaces, and preparing metal prior to coating or inspection. The purple Cubitron II grain is particularly effective on stainless steel, mild steel, and hard alloys where heat generation and grain breakdown are concerns. Professionals in metal trades and industrial finishing operations are the primary installers and users of this consumable abrasive product.

Key Features

• Cubitron II precision-shaped grain for faster cut rates and extended disc life compared to conventional abrasives
• J-weight cloth backing provides flexibility and conformability on contoured or irregular surfaces
• Open-coat construction resists loading and swarf buildup during heavy stock removal
• Resin bond system maintains grain adhesion through sustained, high-load grinding cycles
• Stikit pressure-sensitive adhesive attachment enables rapid disc changes without tools
• Die 500X hole configuration (NH) fits standard 5-inch Stikit disc pads

Compatibility

Designed for use with 5-inch Stikit-compatible disc pads and random orbital sanders that accept the NH center hole Die 500X configuration. No specific model numbers were provided in the product data.

Installation Notes

Stikit discs are installed by pressing the adhesive-backed disc firmly onto a clean, dry Stikit disc pad — ensure the pad surface is free of debris and old adhesive residue before attaching a new disc. Inspect the disc for tears or delamination before each use and discard any disc showing damage. Operators should wear appropriate eye protection and respiratory PPE when grinding metals. Follow the tool manufacturer's maximum RPM rating and confirm the disc RPM rating meets or exceeds that value before operation.
