1.Use highest quality ductile Iron 80000 PSI for minimum bending.
2.The enclosed lead screw and sliding surface are hardened and grounded.
3.Highest clamping power.It’s very accurate and durable.
4.This Vise is designed so that the horizontal force generated by tightening the handle pushes the semi sphere within the movable jaw and thus thrusts the movable jaw downward.
Therefore,the workpiece does not move up,even if it is held at the top of the jaw plates.
5. Four setting positions of the jaw plates are available, widening the jaw plates opening.
6.The new VD675,VD810 have two major improvements-. a wide opening jaw and a new stationary jaw that features an intergral key larger fasteners which reduce deflection by 50%.
