Product Info The Robust 1/2″ Detail Spindle Gouge is made from Hardened and Nitrided M2 tool steel and features a shallow radius flute equal to the diameter of the gouge making it a strong gouge. For instance, the 1/2″ diameter spindle gouges has a flute with a 1/2″ radius. It is shipped sharp and ground with a 45 degree bevel. Robust woodturning tools are manufactured by Robust from premium HSS (high speed steel) that has been treated with our proprietary Nitriding process. Nitriding is not a coating or plating, but a diffusion wherein extra carbon and nitrogen are added to the base metal. This zone is up to .002″ deep. The result: significantly improved edge holding and reduced sharpening. Learn more about the Nitriding process used by Robust tools here.
