60629 - Pferd POLIFAN 4.5-Inch Zirconia Flap Disc 80 Grit Type 29

Pferd POLIFAN High-Density Flap Disc for Industrial Grinding

The Pferd 60629 POLIFAN Flap Disc represents the pinnacle of abrasive efficiency for industrial metalworkers requiring durability and precision. Engineered with a robust Zirconia Alumina abrasive, this 4-1/2 inch disc is specifically formulated to handle the rigorous demands of grinding both carbon steel and stainless steel (INOX). The defining characteristic of this specific model is its "Thick" construction. Unlike standard flap discs, this high-density version is packed with approximately 40% more abrasive material. This enhancement translates directly to a significantly extended service life, allowing operators to work longer without the interruption of frequent tool changes, thereby optimizing production workflow and reducing overall consumable costs.

The disc features a Type 29 conical profile. This angled design is superior for aggressive stock removal and is particularly effective when working on contours, edges, and weld seams. The angle allows for greater surface contact at standard grinding positions, maximizing the utility of the Zirconia grain. With an 80 grit rating, this disc serves as an excellent intermediate tool, bridging the gap between heavy stock removal and final surface finishing. It effectively blends weld beads and removes imperfections while leaving a surface finish that is often paint-ready or suitable for further polishing steps.

Pferd has designed the POLIFAN series to offer a cushioned grinding effect. The arrangement of the flaps provides a degree of flexibility that rigid grinding wheels cannot match. This flexibility reduces vibration transfer to the operator, minimizing fatigue during extended use, and helps prevent gouging of the workpiece. The 7/8-inch arbor ensures compatibility with the vast majority of standard pneumatic and electric angle grinders used in North American fabrication shops. For facilities processing mixed metals, the ability to use a single high-performance disc for both steel and stainless steel simplifies inventory management and ensures consistent results across different projects.

Whether used for deburring, chamfering, or weld blending, the Pferd 60629 delivers consistent cut rates throughout its lifespan. The self-sharpening nature of Zirconia Alumina ensures that fresh cutting edges are continuously exposed as the flaps wear down, maintaining aggressive cutting action until the disc is fully consumed.
