43188 - Pferd POLINOX PNL Drum Finishing Wheel 4-Inch x 2-Inch 100 Grit 5/8-11 Thread

Technical Overview of the Pferd POLINOX Drum Finishing Wheel

The Pferd 43188 POLINOX (PNL) Drum Finishing Wheel is a premium abrasive tool designed for surface conditioning and finishing applications. Engineered with radially arranged flaps of non-woven abrasive material, this tool excels in producing consistent matte and satin finishes on a variety of metals. The 4-inch diameter and 2-inch width provide a substantial contact area, allowing for efficient processing of larger surfaces while maintaining the flexibility needed to contour to irregular shapes.

One of the defining characteristics of the POLINOX series is the dense packing of the abrasive layers. This construction not only extends the service life of the tool but also ensures that the finish remains uniform from the first pass to the last. The 100 grit rating places this wheel in the intermediate finishing category, making it suitable for removing minor imperfections, blending scratch patterns, and preparing surfaces for final high-gloss polishing. The non-woven material structure allows for cool grinding, significantly reducing the risk of thermal discoloration or warping on heat-sensitive materials such as stainless steel and aluminum.

This specific model features a 5/8-11 threaded arbor, a standard configuration that allows for direct mounting onto variable speed angle grinders and specialized polishing machines without the need for additional mandrels or adapters. This integrated mounting system ensures stability during operation and facilitates quick tool changes in high-throughput industrial environments. Whether used for architectural metalwork, tank fabrication, or general maintenance, the Pferd 43188 delivers reliable, professional-grade results.

Key Specifications and Performance

The wheel is optimized for surface refinement rather than heavy stock removal. Its open structure resists loading, ensuring that the abrasive grain remains active and effective. Operators can achieve specific surface roughness values (Ra) by adjusting speed and pressure, providing versatility across different finishing requirements. The tool is compatible with a wide range of materials, including mild steel, stainless steel, non-ferrous metals, and alloys.
