Bull (Mech)
Optimized force flow, minimal deformation, and thus optimal milling results are guaranteed by the pull-clamping system of the Bull Mechanical!
- Precisely repeatable clamping force through use of a torque wrench
- Longevity through encapsulated spindle
- Large clamping range when used with stepped jaws

The patented clamping range adjustment enables rapid adjustment without tedious cranking. The dirt-resistant spindle guarantees trouble-free operation during all machining processes. Through the mechanical clamping force generation via a threaded spindle (without force multiplier), the Bull Mechanical is excellently suited for use with “grip clamping jaws.”

FAQ – frequently asked questions
The detent lugs on the spindle can be turned downwards by hand by 180°.
The movable jaw can then be moved and locked in the desired position.
Positioning against the workpiece and clamping are carried out using a torque wrench with a 1/2"" square drive.
No, the chips can be flushed out of the Bull Mechanical through the large lateral slots or on the spindle side.
The threaded spindle is encapsulated and protected against chips.
Clamping is performed with a torque wrench. The clamping force increases linearly with the set torque to a maximum of 40 kN at a maximum of 105 Nm.
Yes, with the spindle from the Bull Pneumatic + new fixed jaw, the vise can be converted to a pneumatic variant.
Yes, the clamping block can be pulled out backwards together with the jaw and reinserted after being rotated by 180°. This allows the clamping range to be changed very quickly.
These are spring-loaded pressure points. Our Kesel step ledges (support ledges) can be clicked into these.
