Product Info The Robust 3/8″ 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. It comes with a 12″ hard maple handle and a stainless steel ferrule. 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. Flat Milled Gouges: All Robust gouges are flat milled on the top and you can use your sharpening jig all the way down to the end. Gouge Specifications: Blade measures: 0.390″ dia. x 7″, flute measures: 5″ Handle length: 12″, overall length: 19″ shallow radius flute, pre-ground to standard 45 degree spindle gouge profile
