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. Months of testing and trials produced Woodpeckers’ unique nano-grain carbide matrix, polished to a mirror-finish on the cutting surface and precision ground on the bevel, which makes Ultra-Shears the sharpest, longest lasting inserts on the market. 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. It’s a technique called shear scraping, which usually involves trying to balance your tool on a round surface or a sharp corner. Ultra-Shear’s geometry makes shear scraping a simple approach even beginners can use, instead of something that takes years to master. 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.
