62955 - PFERD Polifan Z SGP Strong 5-Inch Flap Disc 36 Grit Zirconia

PFERD Polifan Z SGP Strong Flap Disc – 5" x 7/8" 36 Grit

The PFERD Polifan Z SGP Strong flap disc (SKU: 62955) represents the pinnacle of abrasive innovation for industrial steel fabrication. Designed by PFERD, a global leader in surface finishing solutions, this 5-inch disc is engineered to tackle the toughest grinding challenges with ease. The "STRONG" designation refers to its unique construction, featuring long, compact flaps that provide a significantly higher volume of abrasive material compared to conventional discs. This design translates directly to extended service life and reduced downtime for tool changes, making it a favorite among procurement managers and shop foremen focused on efficiency.

At the core of this disc is a premium Zirconia Alumina (Z) grain. Zirconia is renowned for its self-sharpening properties; as the grains fracture during use, they reveal new, sharp cutting edges. This ensures that the disc maintains a high cut rate throughout its entire lifespan, rather than glazing over or losing effectiveness halfway through the job. The 36 grit coarseness is specifically selected for heavy stock removal tasks, such as leveling heavy welds, aggressive chamfering, and rapid edge breaking on structural steel components.

The disc features a conical (Type 29) profile, which is ideal for contour work and edge grinding. This shape allows the operator to apply higher pressure for aggressive material removal while maintaining control. The robust fiberglass backing plate offers excellent stability and safety, absorbing vibration to reduce operator fatigue during prolonged use. For industrial facilities processing large volumes of steel, the PFERD Polifan Z SGP Strong offers a superior cost-to-performance ratio, delivering consistent, high-quality results on every workpiece.
