62366 - Pferd POLIFAN SG Aluminum Flap Disc 5 Inch 60 Grit Type 27

Pferd 62366 POLIFAN SG A-COOL Flap Disc Overview

The Pferd 62366 POLIFAN SG A-COOL Flap Disc is a high-performance abrasive tool engineered specifically for the challenging demands of grinding aluminum and other non-ferrous metals. Standard abrasives often fail when working with soft, ductile materials because the material melts and adheres to the grain, a process known as loading or glazing. This disc addresses that issue directly with its specialized A-COOL composition.

This 5-inch disc features a Type 27 flat profile, which is optimized for blending, finishing, and working on flat surfaces. The flat orientation allows for a larger contact area, producing a smoother finish compared to conical Type 29 discs. The 60 grit abrasive grain offers a balanced performance, providing efficient stock removal while leaving a high-quality surface finish suitable for subsequent processing or final appearance.

The core technology behind the 62366 is the integration of active grinding fillers in the top coating. These fillers actively reduce the temperature in the grinding zone, preventing the aluminum chips from adhering to the disc. This "cool grinding" effect not only extends the service life of the tool but also protects the workpiece from thermal damage and discoloration. The abrasive material itself is a premium aluminum oxide formulation selected for its toughness and cutting ability on softer metals.

Constructed with a durable backing, this POLIFAN disc ensures safety and stability at high rotational speeds, rated up to 12,200 RPM. It mounts securely to standard angle grinders featuring a 7/8-inch arbor. For industrial MRO operations, fabrication shops, and manufacturing environments where aluminum processing is frequent, the Pferd 62366 offers a cost-effective solution by reducing downtime associated with disc changes and improving overall process efficiency.

In summary, the Pferd 62366 combines advanced chemical engineering with robust physical construction to solve the specific problem of abrasive loading. It delivers consistent cut rates, superior finishes, and exceptional longevity, making it a staple for any professional working with aluminum, brass, or copper.
