Robust 3 Piece Bowl Gouge Set with ER25 Collet Set and Wooden Handle

All Bowl Gouges from Robust Tools are manufactured in the United States using premium high speed steel (HSS). Each tool is treated with a proprietary Nitriding process which results in significantly improved edge-holding and reduced sharpening.



After machining the tools to shape, they are heat-treated 62-64 Rockwell C. The hardened tools then go through the Nitriding process, increasing surface hardness to 1880 Vickers (75+ Rockwell C). Because the treatment is diffused into the metal itself, it will not flake, peel or chip. The tools are just as easy to grind as regular HSS and sharpen well on conventional and CBN wheels.

Gouges are ground on the end, and the cutting edge is defined by the portion ground away and the flute. Since the flute is Nitrided, the cutting edge is also Nitrided.

Each Robust Bowl Gouge features a parabolic flute, which has three main benefits:

1) Having a good size flute for chip ejection

2) Leaving enough metal in the gouge for good strength

3) Sharpenability for both fingernail and conventional grinds (like the 40/40)

Robust uses the American method of sizing their gouges, based on the diameter, not flute width. All Robust gouges are made from slightly oversized stock, and the shanks are turned to the diameter listed in their descriptions.

All Robust gouges are flat milled on the top and you can use your sharpening jig all the way down to the end.
