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). The problem is, the thinner parting tools get, the harder they are to sharpen. Get the end just a little out of square and the tool won’t cut straight. If the edges get a little rounded over, you’ll get tear-out at the entry point. 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 computerized equipment, polished to a razor-like edge and replaceable in seconds.
As if a thin-kerf carbide parting tool wasn’t enough, Woodpeckers 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 tropicals…they all cut cleanly. If you need a perfectly flat bottom, there’s an optional fully-square carbide insert.
The carbide insert is just slightly under 3/32" (.0825" to be precise). The blade holding the insert is 1/16". The difference gives you .010" (“ten thou” in engineer-speak) 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. The other insert parting tools on the market use inserts designed for metalworking machinery. The geometry of those inserts relies on consistent pressure from exactly the same contact point to keep the insert seated. Put them in a hand-held tool and it doesn’t take much of a slip for the insert to fly out. But, 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. 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, Ultra-Shear’s Parting Tool Ci is for you.
