Taper end mill is used to make a taper hole by a plunging operation. A hole should be machined prior to the machining of the taper end mill. The hole size should be greater by 0.2 or 0.3 than the minor diameter of the taper end mill. Application for such end mill is found where compressor plate slots are machined. These plates are made of stainless steel(SS 420).
feed = 0.03-0.04 mm per tooth.
cutting speed =100 m/min.
