Application tips

Torque wrench

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

    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
