The Robust 5/8″ Bowl Gouge features a parabolic flute and is made from Hardened and Nitrided M2 tool steel. It comes with a 16″ hard maple handle and a stainless steel ferrule. It is shipped sharp and ground with a double bevel. Parabolic flutes give a great combination of strength and chip ejection. They are amenable to finger nail (Ellsworth or Irish) grinds, conventional bowl gouge grinds and the “40/40” grind.
Robust woodturning tools are manufactured by Robust from premium HSS (high speed steel) that has been treated with a 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.
Parabolic Flutes: Our bowl gouges feature a parabolic flute. Parabolic flutes optimize three things: 1) having a good size flute for chip ejection, 2) leaving enough metal in the gouge for good strength and 3) sharpenability for both fingernail and conventional grinds (like the 40/40).
