Love Turning but Hate Sharpening? If you love woodturning, but dont have the time or expensive equipment necessary to constantly sharpen traditional tools, you need Woodpeckers new Ultra-Shear carbide insert tools. These tools eliminate the drudgery of sharpening by using nano-grain carbide inserts mounted to induction-hardened alloy steel shafts. When the edge finally gets dull (more on that later), simply rotate the cutter to a new edge. When all edges are dull, put on a new insert and get right back to your project.

So, Whats New? Carbide insert tools have been around for several years, and insert tools in general have been around since at least the mid-1980s. So, what makes Ultra-Shear different from all the rest? The list is long, but the three most important differences are the grade and grind of the inserts, the design of the tool shaft and the material and treatment used in making the shaft.

It All Starts at the Cutting Edge. Ultra-Shears development team started this project by interviewing dozens of carbide manufacturers, seeking out a partner that recognized the unique requirements of woodturning. Any carbide blend can create a long-lasting edge, but for advanced performance at the lathe, you need a truly keen edge. That requires a carbide that doesnt just last, but also is fine-grained enough not to crumble when formed to a really sharp angle. The result of months of testing and trials is a unique nano-grain carbide matrix, polished to a mirror-finish on the cutting surface and precision ground on the bevel. They are the sharpest, longest lasting inserts on the market.

Go Beyond Just Shaping your Project. Carbide insert turning tools are typically used with the tool on the centerline of the lathe, held horizontal to the ground. Ultra-Shear tools use this approach for roughing and shaping cuts. But, Ultra-Shear goes further. After initial shaping, roll the tool right or left and you will feel the tool land on another bearing plane, 45? from horizontal. With the tool at this angle, the wood fibers slice cleanly, leaving a surface that needs little or no sanding.  Its a technique called shear scraping , which usually involves trying to balance your tool on a round surface or a sharp corner. Ultra-Shears geometry makes shear scraping a simple approach even beginners can use, instead of something that takes years to master.

High Tech Steel; Higher Tech Manufacturing. A truly sharp cutting edge needs rock solid support to give you the best results. Ultra-Shear tools feature the same ChroMoly alloy steel used in NASCAR roll cages and crankshafts. CNC machines create the unique profile, then the shafts go through a two-step hardening process that makes the shaft rigid and creates an ultra-smooth surface finish that glides easily across your tool rest and resists corrosion.

The full size tools have an 8" tool length (beyond handle) with a 15-3/4" handle, for a total length of 23-3/4".  The mid size tools have a 4-1/2" tool length with an 11" handle for a total length of 15-1/2". The pen tools have a 3-1/4" tool length with a 9" handle for a total length of 12-1/4".
