This is a tangential tool holder I just finished. Tool holder hold at the 15* cutting angles front and side so only top needs to be ground. Mush shorter set up so more rigid. There is the fixture to grind the top of the tool at 15* and it gives a hollow grind thats very sharp and easy to repeat.
The aluminum bar is a test cut with it. 600 rpm .050 depth of cut .010 feed the face was cut 600 rpm .025 depth of cut and .010 per revolution. It does the same in steels and brass.
Turn the cutter 90* and its a shear tool that gives a very good finish but only .002-.005 passes.
