I am having issues keeping my .065" HSS parting blade held in my Knock-off Aloris AXA parting tool holder. When I tighten it down it wants to rotate leaving a gap on the top. It also rotates horizontally. I can fix the horizontal movement by moving the tool post but the tilt I cannot. I have thicker Somma T-type Parting blades and I dont have either of these issues with them. I have machined a horizontal groove the length of the holder so that the T-section of the blade can lay flat against the tool holder but it still kicks out on me. Any suggestions? Maybe machine a taper or angle on the wedge so that it pulls the parting blade in and down as I torque it down?
