Extending the life of expensive cutting tools is always a goal. Toward that end, Emuge has introduced the Softsynchro 0 Tap Holder with coolant-through capability. It is designed for tap ranges #2-10 and M2-M8, while the existing Softsynchro 4 handles tap ranges 7/6-1 in. and M12-M30. Units are constructed from two separate, precision ground sections: the body and the shank. Elastomer springs separate the spindle from the tap, absorbing excessive axial forces and compensating for small errors in the machining process. Torque from the spindle is transferred seamlessly to tap via ball bearings riding in precision ground grooves. According to Emuge, the tap holder dramatically increases tool life in a rigid tapping environment, with tests showing an up to 4x increase in tool life.A wide variety of shanks are available, including HSK, BT and SK, with adapters for more to cover most machine spindles.
