67192 - PFERD POLIFAN-CURVE 4-1/2 Inch Flap Disc, 40 Grit Zirconia, 7/8 Arbor

Revolutionary Fillet Weld Grinding with PFERD POLIFAN-CURVE

The PFERD 67192 POLIFAN-CURVE Flap Disc represents a significant leap forward in abrasive technology, specifically engineered to address the challenges of working on fillet welds. Part of PFERD's Special Line SGP, this tool is designed for tasks that demand high performance and ultimate economic efficiency. Unlike conventional flap discs that primarily utilize the outer edge for grinding, the POLIFAN-CURVE features a patented radial configuration. This unique shape allows the abrasive flaps to wrap around the periphery of the disc, enabling the user to grind with the edges, the face, and the top surface of the disc. This versatility is unmatched in the industry and provides a comprehensive solution for complex geometries.

At the core of this 4-1/2 inch disc is a premium blend of Zirconia and Aluminum Oxide grains. This combination is selected for its aggressive stock removal capabilities and its ability to maintain a cool grinding temperature, which is critical when working with heat-sensitive materials like Stainless Steel (INOX). The 40 Grit specification ensures rapid material removal, making it ideal for heavy-duty grinding, weld seam removal, and chamfering. The "Medium Radius" design is tailored to fit standard fillet weld profiles, ensuring that the disc conforms to the workpiece rather than gouging it. This results in a precise, high-quality finish that reduces the need for subsequent rework.

Durability and workpiece protection are also key features of the PFERD 67192. The disc is constructed with a consumable fiberglass backing that wears down with the abrasive. This design choice prevents the backing from melting, smearing, or scratching the workpiece, a common issue with inferior plastic-backed discs. Furthermore, the radial construction ensures that the abrasive material is utilized fully, from the outer edge down to the core, providing a significantly longer service life than standard flat or conical discs when used in fillet applications. Whether you are working on structural steel or fine stainless fabrication, the POLIFAN-CURVE delivers consistent, professional results.

Key Applications:

• Precise grinding of fillet weld geometries.
• Heavy stock removal on steel and stainless steel.
• Chamfering and deburring.
• Repair applications requiring underhand grinding.
