(Above parameter is for BT50 arbor) 2) In case chatter occurrs, recommend to reduce depth of cut or spindle speed and feed speed. 3) Use air blow to flush the chips out. 4) We recommend to use XDMW080635ZTR-S JC8015 (negative geometry inserts) for material having sand C116 inclusions and uneven removal stocks.
