All Spindle and Detail 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.

Spindle/Detail Gouges feature shallow radius flutes equal to the diameter of the gouge. All Robust gouges are flat milled on the top and you can use your sharpening jig all the way down to the end.

Each Robust 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.
