48E009 - Walter 6-inch Hook and Loop Backing Pad for Big Buff III

Technical Overview of the Walter 48E009 Contact Plate

The Walter 48E009 is a specialized contact plate designed to serve as the interface between rotary power tools—specifically the Walter Big Buff III—and various finishing accessories. Engineered with a 6-inch diameter, this backing pad provides the optimal surface area for standard polishing and cleaning discs used in metal fabrication and surface finishing applications.

The unit features a standard 5/8"-11 internal thread, making it compatible with the spindles of most North American angle grinders and polishers, though it is optimized for the torque and speed characteristics of Walter's finishing tools. The face of the plate utilizes a high-quality hook and loop (Velcro-style) fastening system. This design allows operators to switch between different grits of non-woven pads, felt polishing discs, or cleaning fleece instantly without the need for tools or locking nuts.

Structurally, the plate is constructed from a durable, slightly flexible polymer material. This flexibility is crucial for finishing work, as it allows the abrasive media to contour slightly to the workpiece, reducing the risk of gouging and ensuring a uniform finish. The material is also heat-resistant, preventing deformation during the friction-heavy polishing process. This component is essential for shops utilizing the Big Buff system for mirror-finishing stainless steel or cleaning weld discoloration.
