3M 7100224736 Flexible Diamond Qrs Cloth Disc 9x1 in

Product Description

The 3M 7100224736 is a flexible diamond abrasive cloth disc designed for heavy-duty material removal and finishing on hard-to-grind surfaces. Built on a QRS hook-and-loop backing, it features micron-graded diamonds secured with a metal-plated bond that firmly anchors the abrasive layer for consistent, long-lasting performance. At 9 inches in diameter with a 1-inch thickness profile and an M74 Micron Pattern 18 configuration, this disc delivers improved durability in demanding grinding applications while maintaining a refined surface finish without sacrificing cut rates. It is suited for professional trades requiring precision abrasive work on dense or brittle workpiece materials.

This disc is intended for use on hard and abrasion-resistant materials including stone, glass, ceramic, metal, carbide, and composites. The QRS hook-and-loop attachment system allows for fast disc changes on compatible random orbital or disc sanders, making it practical in production shop environments, fabrication facilities, and field service settings where downtime between abrasive changes must be minimized. The flexible cloth backing conforms to slightly contoured surfaces, which is especially useful when finishing curved stone or composite panels.

Key Features

• Metal-plated bond securely anchors micron-graded diamonds to the disc surface for extended service life
• QRS hook-and-loop backing enables tool-free disc changes on compatible Sanders
• Flexible cloth construction conforms to contoured or irregular workpiece surfaces
• M74 Micron Pattern 18 abrasive layout balances cut rate with surface finish quality
• Engineered for hard-to-grind materials: stone, glass, ceramic, metal, carbide, and composites
• Improved durability designed for demanding, high-cycle grinding and finishing applications

Compatibility

Designed for use with QRS hook-and-loop compatible disc sanders and random orbital tools that accept 9-inch abrasive discs. Suitable for grinding and finishing stone, glass, ceramic, metal, carbide, and composite materials.

Installation Notes

This disc is installed and serviced by machinists, fabricators, and skilled tradespeople working with abrasive equipment. Ensure the sander or grinder is fully powered down and unplugged before mounting or removing any abrasive disc. Confirm the tool backing pad is clean and in good condition before attaching the QRS disc to ensure proper engagement of the hook-and-loop interface. Always wear appropriate PPE including eye protection and gloves when operating grinding or sanding equipment on hard materials.
