This video demonstrates Dapra's 1" Toroid End Mill executing a pocketing routine in steel. The material is 4140PH (30 Rc), and the machine tool used is a Fadal 4020 with a 40-taper spindle.
This particular pocketing routine utilizes a medium IC insert (1/2") at a coarse pitch for more depth of cut capability at a moderate feed rate. This method is typically preferred on heavier-duty machines, but the free cutting design of the RHINO-CARB insert allows for this even on lighter-duty (40-taper, linear ways) machines.
