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 smaller IC insert (3/8") at a fine pitch for more feed capability at a lighter depth of cut. This method is usually preferred on lighter-duty (40-taper, linear ways) machines, as it allows the machine to function within its designed capabilities.
