BlueFire R860 ZA Coarse Grit TR (Type III) Plastic Flat Mini Fla - Norton Company

The Norton BlueFire R860 ZA Coarse Grit TR (Type III) Plastic Flat Mini Flap Disc (Model 776960-90172) is engineered for efficient material removal in tight access areas often inaccessible to larger discs. Featuring a high-performance Zirconia Alumina (ZA) grain, this disc provides a consistent cut rate and extended durability across various automotive and industrial metals, making it a professional choice for demanding grinding and deburring tasks.

Key Features

• Durable Zirconia Alumina (ZA) Abrasive: This self-sharpening abrasive grain offers aggressive material removal and an extended operational lifespan, ideal for continuous professional use on steel, stainless steel, and other metals. Zirconia alumina is known for its high hardness and strength, performing well under high temperature and extreme pressures.
• Coarse Grit Formulation: Effectively removes heavy rust, scale, old coatings, and weld spatter, streamlining surface preparation processes for welding or coating.
• TR (Type III) Quick-Change Backing: Ensures secure and stable attachment, facilitating quick disc changes on compatible mini right-angle tools without requiring additional tools.
• Compact Mini Flat Design: Allows for precise grinding and deburring in confined spaces and intricate geometries where larger discs cannot reach, such as inside corners or small components.
• Flexible Plastic Backing Plate: The high-strength plastic backing provides flexibility and absorbs vibration, contributing to a more ergonomically friendly experience for the operator.

Applications

This mini flap disc is an essential tool for automotive repair, fabrication, and industrial maintenance shops. It excels in grinding and deburring tasks within confined areas on vehicle frames, crossmembers, engine and transmission brackets, and suspension components. Technicians will find it highly effective for cleaning welds, blending transitions, breaking sharp edges, and removing rust or paint from machinery parts prior to welding or coating. Compatible with mini grinders and die grinders that accept TR (Type III) quick-change discs, it performs reliably on various metals including stainless steel, carbon steel, alloyed steel, and aluminum.
