(In case of BT40 or below, recommend to use tool dia. below φ33) 2) In case of chatter occurrs, recommend to reduce depth of cut or spindle speed with keeping feed per tooth. 3) If machine does not have enough power, recommend to reduce depth of cut first and reduce spindle speed and feed speed. 4) Use air blow to flush the chips out. 5) In case of 50-55HRC (Hardened die steel), recommend to reduce 30% above ap, n, Vf. 6) In case of unfavourable conditions, insert grade JC8050 is recommended.
