Woodpeckers Ultra-Shear Turning Tools - Parting Tool Ci

by Woodpeckers

Narrow, crisp, and clean parting cuts are easy to achieve using this Woodpeckers Ultra-Shear Parting Tool equipped with a replaceable carbide insert or Ci for short.

Woodturners love narrow parting tools because they allow you to get more turning from less stock, they cut with less resistance, and they open up other design options (like the grooves of a honey dipper) not possible with wider blade parting tools. The problem is, the thinner parting tools get, the harder they are to sharpen. The Ultra-Shear Parting Tool Ci changes all that by eliminating sharpening altogether. Instead, the cutting edge is a nano-grain carbide insert, ground on computerised equipment, polished to a razor-like edge and replaceable in seconds utilising the included removal and installation tool.

As if a thin-kerf carbide parting tool wasn’t enough, we also fluted the insert, creating a profile that makes an incredibly clean entry cut on even the trickiest woods, from open-grained softwoods to ultra-dense tropical hardwoods. If you need a perfectly flat bottom, there’s an optional Ultra-Shear Square Insert for the Parting Tool sold separately. The carbide insert is just slightly under 3/32" (2.095mm to be precise). The blade holding the insert is 1/16" (1.59mm). The difference gives you .010" (0.25mm) clearance on each side of the blade. Bottom line, with that clearance you’ll never burn your project or your tool again.

Woodpeckers also designed the blade holder to keep the inserts where they belong. Ultra-Shear’s re-designed geometry takes the wedge theory and improves it with a profiled feature that grips the insert securely, even at odd approach angles.

Woodpeckers patterned the handle and blade after thin-kerf parting tools first made popular in England in the 1980s. The tall blade resists twisting and bending, while the short blade length and knife-style handle give you comfortable, confident control over the cut.

If you’re looking for a parting tool that cuts clean each and every time you pick it up and never needs sharpening, the Ultra-Shear Parting Tool Ci is ideal for you.
