Internal axial recesses effectively prevent the tool slipping.
High radial stiffness due to repeatable clamping accuracy against a flat face, which prevents misalignment and ensures a high accuracy of machining, coupled with long tool life.
T-slots take up the oil and grease, so that reliable torque transmission is achieved.
Absolutely smooth running of the clamping nut.
For clamping tools with plain shanks.
