63031 - Pferd POLIFAN 5-Inch Zirconia Flap Disc 40 Grit Type 29 for Stainless Steel

High-Performance Grinding for Stainless Steel Applications

The Pferd 63031 POLIFAN® Flap Disc is a premium abrasive tool engineered specifically for the demanding requirements of industrial metalworking. Designed with a Type 29 conical profile, this 5-inch disc features an ergonomic angle of attack that maximizes surface contact, making it exceptionally effective for contouring, edge grinding, and heavy weld seam removal. The conical shape allows the operator to apply higher pressure for aggressive stock removal while maintaining control and comfort during extended use.

At the core of this disc's performance is its high-quality Zirconia Alumina abrasive grain. Zirconia is renowned in the industrial sector for its toughness and self-sharpening characteristics. As the grains fracture during the grinding process, they expose new, sharp cutting edges, ensuring consistent cutting rates throughout the life of the disc. This specific model is optimized for Stainless Steel (INOX) applications. It incorporates active grinding fillers that promote cool cutting, significantly reducing the risk of thermal buildup. This is critical when working with stainless steel, as excessive heat can lead to discoloration (heat tint) and compromise the corrosion resistance of the material.

With a coarse 40 grit rating, this flap disc is the ideal choice for the initial stages of fabrication where rapid material removal is the priority. It excels at leveling heavy welds, removing deep scratches, and preparing surfaces for finer finishing steps. The 7/8-inch arbor ensures compatibility with a wide range of standard pneumatic and electric angle grinders. By combining aggressive cutting action with a durable backing and cool-grinding technology, the Pferd 63031 reduces process time and consumable waste, providing a cost-effective solution for professional fabricators and MRO specialists.

Technical Specifications and Usage

This disc is rated for high-speed angle grinders and delivers its best performance when used with high-powered tools that can maintain rotational speed under load. The layered flap construction not only provides a cushioned grind that reduces vibration but also reduces noise levels compared to rigid grinding wheels. For optimal safety and performance, ensure the grinder does not exceed the maximum RPM rating of the disc.
