Turner’s Edge woodturning tools are manufactured by Robust Tools. Bowl gouges have parabolic flutes and spindle gouges have radius flutes. Turner's Edge gouges are made using Nitrided M2 High Speed Steel. All flutes are polished to remove tool marks.
What's special about Nitriding? Nitriding is frequently used on carbide and high speed steel cutting tools to improve their performance when machining metals. Not a coating or plating, Nitriding describes a treatment wherein carbon and nitrogen are added to the base metal and form a diffused zone within the surface of the tool. This zone is up to .002" deep. Nitriding reduces surface friction, improves wear resistance and significantly enhances edge holding. During product development, Robust Tools tested a number of different Nitriding treatments and selected a superior form that works especially well with woodturning tools.
To make Turner's Edge gouges, we start with premium high-speed steel (M2). After machining, the tools are heat treated to 64 Rockwell C. The hardened tools then go through the Nitriding process, increasing cutting edge hardness to 1880 Vickers (75+ Rockwell C). Because the treatment is diffused into the metal itself, it will not flake, peel or chip.
The result: Longer edge holding and smoother chip ejection from the polished flute.
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.
Spindle Gouges feature radius flutes that are not as deep as the parabolic flutes found on the bowl gouges. The radius equals the diameter of the spindle gouge. For instance, the 1/2" diameter spindle gouges has a flute with a 1/2" radius.
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.
Lengths: The 1/2" and 5/8" gouges are 11.75" long and the full depth of the flute is 7.5". The 3/8" gouges are 8.75" long and the full depth of the flute is 4.75 - 5".
Handles: All of the gouges are are offered with and without handles. The handles are hard rock Maple, and turned to our specification in Pennsylvania. All have stainless steel ferrules. We also offer a line of collet based tool handles and kits to make your own handle using our collet system. Click the product tab at the top of the page to learn more.
