Another shear tool

[olderdan]

Inspired by Tony Foales carbide shear tool version I had to make mine in a different way without the use of a milling machine. I had a ½ square braised carbide tool which I turned the shank down to a 3/8 dia to fit a square tool block from my cutter grinder which fits my tool holder, this does have the facility to vary the shear angle to suit different materials. Apart from the excellent finishes it produces it is very useful for work hardening steels which do not allow a small final cut to size, this tool will shave off a tiny finishing cut. These tools do have a limitation when working to a shoulder but raising the tool close to the bottom edge will do for most items.
