60626 - Pferd POLIFAN Zirconia Flap Disc 4-1/2" Type 29 40 Grit

Heavy-Duty Grinding with Pferd POLIFAN Technology

The Pferd 60626 POLIFAN Flap Disc represents a significant advancement in abrasive technology for industrial metalworking. Engineered for professionals who demand longevity and performance, this 4-1/2 inch disc features a robust Zirconia Alumina grain structure. The "Thick" designation indicates that this specific model is built with approximately 40% more abrasive material than standard PSF flap discs. This increase in material density translates directly to extended service life, allowing operators to work longer without stopping to replace consumables, thereby increasing overall shop productivity.

Designed with a Type 29 conical profile, this flap disc is optimized for aggressive stock removal and contour work. The angled flaps allow for greater surface contact at comfortable working angles (typically 15 to 25 degrees), making it ideal for grinding down heavy welds, chamfering edges, and blending surfaces on complex geometries. The 40 grit rating ensures rapid material removal, effectively tackling heavy slag and mill scale on both carbon steel and stainless steel (INOX) workpieces.

One of the standout features of the Pferd POLIFAN series is the special flap arrangement. This design provides a unique flexibility that results in a "cushioned" grinding effect. Unlike rigid grinding wheels that can transfer harsh vibrations to the operator, this flap disc absorbs some of the impact, reducing user fatigue during prolonged use. Furthermore, the Zirconia grain is self-sharpening; as the abrasive wears down, new sharp edges are exposed, maintaining a consistent cut rate throughout the life of the disc. Compatible with standard 4-1/2 inch angle grinders featuring a 7/8 inch arbor, the Pferd 60626 is a versatile and essential tool for fabrication, maintenance, and repair operations.
