Abstract
A blade for cutting multi-angle valve seat profiles has a plurality of angles machined on its surface which combine to form rake and relief angles that machine concentric valve seats and chatter free finishes. The method of machining several valve seat angles in one cycle of valve cutter as opposed to having multiple valve seat cutters at different angles will accelerate the task of machining valve seats on cylinder heads on internal combustion engines.
