Quick viewRobust Turning Tools
$ 59.00 – $ 169.00View productsDetailsRobust woodturning tools are manufactured from premium HSS (high speed steel) that has been treated with our proprietary Nitriding process.
What's special about Nitriding? We're certainly not the first to Nitride cutting tools. For instance, all of the carbide and HSS cutting tools we use to machine these tools here in our shop are Nitrided. 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.
To make our tools, we start with premium HSS of either M2 or M42. 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 up to 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.
But isn't the Nitriding Ground Away during Sharpening? 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. For scrapers, whether conventional or negative rake, just grind the bottom bevel. This leave the Nitriding on the top surface, so the burr is Nitrided. You are correct about skews though, there will be no Nitriding on the cutting edge. Still, it's M42, which is pretty darn good steel. You'll also like the radius on the edges of our skews and scrapers, and this really makes them more versatile for a number of different cuts.
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).
Spindle/Detail Gouges feature shallow radius flutes equal to the diameter of the gouge. For instance, the 1/2" diameter spindle gouges has a flute with a 1/2" radius.
Speaking of Diameters: We use the American method of sizing the gouges, based on the diameter, not flute width. All gouges are made from slightly oversized stock, and the shanks are turned to the diameter listed in their descriptions.
Handles: All tools are offered with and without handles. The handles are hard rock Maple, turned to our specification in Pennsylvania. All have stainless steel ferrules. We also offer a line of collet based tool handles and collet kits. Click the product tab at the top of the page to learn more.

Quick view5/8 Bowl Gouge – with 16″ Maple Handle
$ 129.00Add to cartDetails
Our 5/8" bowl gouge features a parabolic flute and is made from Hardened and Nitrided M2 tool steel. 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.
The handle is hard rock maple and turned for us in Pennsylvania. The ferrule is stainless steel. Also available unhandled. -
Quick viewSmall Detail Skew – Handled
$ 99.00Add to cartDetails
Our small skew is made of M2 and measures 1/2” by 1/4". The edge is beveled 20 degrees and has been hollow ground on an 8” diameter wheel before honing to a razor sharp edge. The cutting edge of the gouge has been ground to a gentle 3/4” radius. We consulted with noted turner Matt Monaco on the profile of this grind. The radius of the profile has a small return at the top, adding versatility for cutting beads and adding details.
The lower edges of the gouge have a generous radius to help rolling the gouge to make beads and coves. The top edges also have a small radius. The premium hard maple handle has a durable polyurethane finish and stainless steel ferrule.

Quick viewLarge Spear Scraper – Unhandled
$ 99.00Add to cartDetails
Our large spear scraper is made of nitrided premium HSS and measures 1” across and 5/16 thick. The bottom edges are radiused so that you can use it at an angle for even more effective cutting. The tang is rectangular, but will fit the 5/8" collet in either of our ER Collet based handle systems.
Spear scrapers are great at two things: shear scraping the outside of convex shapes like bowls and hollow forms with their long curved edges, and adding details with the point.
When used to shear scrape on the outside of convex shapes, they are often raised up on one edge to improve the shear angle. We put a generous radius on these edges to facilitate use in this way. They can also be used like regular scrapers on the inside of open shapes, like shallow bowls and platters.
The point is great for adding decorative grooves and beads to the exterior of your pieces.
