67343 - PFERD POLIFAN-CURVE 5-Inch Fillet Weld Flap Disc 40 Grit

Revolutionary Fillet Weld Grinding

The PFERD POLIFAN-CURVE Flap Disc (Type 29, 5" x 7/8", 40 Grit) represents a significant innovation in abrasive technology, specifically engineered to tackle the challenges of fillet weld grinding on stainless steel. Unlike conventional flap discs that only utilize the face of the abrasive, the POLIFAN-CURVE features a unique radial construction where the abrasive flaps wrap around the periphery of the disc. This patented design allows operators to grind directly into tight corners and fillet welds with the edge of the tool, ensuring complete penetration and a smooth finish without gouging the workpiece.

Designed for heavy-duty industrial applications, this 40-grit disc delivers aggressive stock removal rates, making it ideal for leveling welds and removing defects quickly. The specialized abrasive formulation is optimized for stainless steel (INOX), preventing heat buildup and discoloration that can compromise the integrity of the material. The Type 29 conical shape further enhances ergonomics by providing a comfortable working angle, reducing operator fatigue during extended use.

Durability is a hallmark of the POLIFAN-CURVE series. By utilizing the abrasive material on the radius of the disc, PFERD has significantly increased the usable surface area, resulting in a tool life that far exceeds standard flap discs in fillet applications. This efficiency translates to fewer disc changes, lower consumable costs, and increased productivity on the shop floor. Whether you are repairing defects or finishing complex geometries, this disc offers a versatile solution that combines the capabilities of a grinding wheel and a flap disc into one high-performance tool.
