60630 - PFERD POLIFAN 4.5-Inch Zirconia Flap Disc 120 Grit Type 29

Premium Zirconia Flap Disc for Industrial Finishing

The PFERD 60630 POLIFAN Flap Disc represents a high-standard solution for metalworkers requiring precision finishing and light grinding capabilities. Engineered with a Type 29 conical profile, this 4-1/2 inch disc is optimized for contour work and edge grinding, allowing the operator to maintain a comfortable 15 to 25-degree angle during application. The conical shape maximizes surface contact area for more aggressive stock removal when needed, while the 120 grit abrasive ensures a smooth, refined surface finish suitable for pre-paint preparation or final aesthetic blending.

At the core of this abrasive tool is premium Zirconia Alumina grain. Zirconia is renowned in the industrial sector for its self-sharpening properties; as the grains fracture during use, they reveal new, sharp cutting edges. This characteristic significantly extends the service life of the disc compared to standard aluminum oxide alternatives, maintaining a consistent cut rate and finish throughout the product's lifespan. The specific formulation used in this PFERD disc is designed to be versatile, offering exceptional performance on both Carbon Steel and Stainless Steel (INOX). This dual-material capability (STEELOX) simplifies inventory management for shops working with multiple metal types.

One of the standout features of this specific model is its enhanced flap arrangement. The construction provides a degree of flexibility that creates a cushioned grinding effect. This reduces vibration and operator fatigue while preventing gouging on the workpiece, a critical factor when performing finishing work with finer grits like 120. The disc is built with a robust fiberglass backing that provides stability and safety at high rotational speeds. With a standard 7/8-inch arbor, it is compatible with the vast majority of industrial 4-1/2 inch angle grinders available on the market. Whether used for blending weld seams, removing light rust, or preparing surfaces for coating, the PFERD 60630 delivers professional-grade results.
