The OTT universal inside spindle contour is an important step towards modular tooling. It offers the manufacturer of machines and/or spindle units the ability to clamp different steep taper tools (taper/retention knob standard) simply by exchanging the gripper unit.

Several variations of power drawbars with or without coolant, with hydraulic or pneumatic unclamp units can be built into the same spindles. Rotary unions and unclamp units are compatible and exchangeable.

The assembly of the OTT-Jakob Power Drawbars can be done easily and quickly by average personnel.
