Application tips
Torque wrench
Always use torque wrench 5680 099-01 for best performance and repeatability. The actuating screw shall always hit the mechanical stop, torqued with 8 Nm for S, T, P and 10 Nm for HD for best performance. If the screw does not hit the mechanical stop with recommended torque, check torque wrench status and actuating screw status.
Collets
CoroChuck® 930 can be used with or without reduction collets. For internal coolant use 393.CGS collets and for external coolant use 393.CG, 393.CF and 393.CLF
