Ductile steel body with hardened and ground movable steel jaw.
All surfaces are precision ground and the bed is flame hardened
Spherical segment allows for all directional alignment
When clamping, a downward pressure of 1kg is exerted by the movable jaw for every 2kg of clamping pressure, preventing the work piece from tilting
Bearing thrust collar cuts friction and increases clamping pressure
Swivel base is graduated to 360º
