Product Info The Robust 5/8″ Detail Spindle Gouge is made from Hardened and Nitrided M2 tool steel and has a radius flute that matches the diameter of the stock. 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: 0.632″ dia. x 11.5″ overall, flute measures: 7″ shallow radius flute, pre-ground to standard 45 degree spindle gouge profile Tang: 0.625″ diameter x 2″ long
