About Working Boards

prototyping tooling boards in various colorsRAKU® TOOL Working Boards (WB) are dense and strong combining high quality with excellent mechanical properties. They require relatively slow machining speeds due to their high density.

Length, width, thickness, and diameter tolerances vary by size, by manufacturer, brand, and grade.
