07K442 - Walter Two-In-One Flap Drum 4-1/2 x 4 Inch for Aluminum

Efficient Dual-Action Finishing Drum

The Walter Surface Technologies 07K442 Two-In-One Drum is a premium abrasive tool engineered to streamline the metal finishing process. Manufactured in Germany, this 4-1/2" x 4" drum features a unique construction that interleaves aggressive coated abrasive cloth with Walter's proprietary BLENDEX non-woven flaps. This hybrid design allows the operator to perform two distinct finishing stages simultaneously: the abrasive cloth removes surface imperfections, scratches, and handling marks, while the BLENDEX flaps follow immediately behind to blend the surface and generate a consistent satin line finish.

Designed specifically for efficiency, the Two-In-One drum is particularly effective on aluminum and other non-ferrous metals, where surface loading and consistency can be challenging. By consolidating the grinding and conditioning steps, industrial users can significantly reduce process time and labor costs. The drum is compatible with standard linear finishing tools (burnishers) and is built to withstand the rigors of heavy industrial use. Whether used in fabrication shops, architectural metalwork, or equipment manufacturing, this tool ensures a uniform aesthetic without the need for multiple tool changes.

The open structure of the BLENDEX material helps resist loading, ensuring the abrasive cloth maintains contact with the workpiece for a consistent cut rate throughout the life of the drum. This product represents a smart solution for MRO professionals seeking to optimize their surface finishing workflows on soft metals.
