62225 - Pferd POLIFAN 5-Inch Zirconia Flap Disc Type 29 40 Grit for Steel

High-Performance Zirconia Abrasive for Industrial Steel Applications

The Pferd POLIFAN Type 29 Flap Disc (SKU: 62225) represents the pinnacle of abrasive engineering for steel fabrication. Designed as part of the Superior line, this 5-inch disc utilizes premium Zirconia Alumina grain, renowned for its toughness and self-sharpening characteristics. Unlike standard aluminum oxide discs, Zirconia Alumina fractures under pressure to reveal fresh, sharp cutting edges, maintaining a high cut rate throughout the life of the disc.

This specific model features a Type 29 conical profile. The angled design allows for greater surface contact when held at the standard 15 to 25-degree grinding angle, making it significantly more aggressive than flat (Type 27) alternatives. This geometry is ideal for contour work, edge chamfering, and heavy weld seam removal where speed and stock removal are critical priorities.

Engineered specifically for steel, the bonding agent prevents the glazing often seen when grinding soft or gummy ferrous metals, ensuring the disc remains effective until the abrasive cloth is fully consumed. The 40 grit coarseness is perfectly suited for the initial stages of fabrication, capable of rapidly leveling welds and removing heavy mill scale. The robust fiberglass backing plate provides necessary stability and vibration absorption, enhancing operator comfort during prolonged use.

Operational Efficiency

By combining a high stock removal rate with extended service life, the Pferd POLIFAN Superior series reduces the frequency of tool changes. This efficiency translates directly to lower operational costs and increased throughput in high-volume production environments.
