TECHNICAL INSTRUCTIONSABSEATINGSof MINI as well as SUPER − MINI guarantee the accurate center height of these tools.In spite ofthis always check center height because a difference may cause problemsespecially when machining small diameters.TORQUE OF SCREWS FOR MINIFollowing torques are allowed for screws of MINI inserts. We recommend not to use additionalmeans (such as copper paste) for screws.Screw T8(type108) T10(type111) T15(type114) T20(type116)Torque lbf-in. 9 − 1 3 22 − 26 35 − 40 50 − 55REMOVAL OF CHIPSPlease choose inserts with small cutting widths, which helps chips evacuation and chip flowout of the bore beside the tool. To avoid jam of chips use the technique to groove by steps.COOLANTUse a filtered coolant for transporting the chips out and for cooling the insert itself.A coolant pressure of75 psi min. is recommended.UNCOATED GRADESMG1 2 −a universal grade with good wear resistance. Used at low or medium cutting speeds formachining steel, cast iron and non ferrous materials.COATED GRADESTN35 −TI25 −TF45 −a very popular grade TIN coated used to low or medium cutting speeds. Also recommendedfor machining stainless steel or exotic alloyed materials.a TICN coated grade with high abrasion resistance. Recommended for machining steel andnon ferrous materials at medium cutting speeds.a TIALN coated grade. This coating has a very high temperature stability and high hardness.Machining small bores, therefore it is only used for special applications.In the UNITED STATES call us toll freeB65
