Toolmakers Sine Vice - Screw Type - Sturdy Engineering Tools

These sine vices mounted onto a precision hinged bottom plate. All the surfaces of the vice are precisely ground for extreme accuracy. Tool Makers vices are manufactured from special tool steel.
These solid one piece vices are fully hardened (55-60 HRC) and tempered to ensure stability and durability.
These vice surfaces are precision ground. Due to their precise accuracy these vices are mainly used in tool manufacturing, on grinding machine, milling machine and for inspection purpose also. In Screw type Grinding Vices clamping and releasing is through a threaded spindle with precision cut square threads for smooth operation.
A minute angle step of 0.2″/5 mm allows very small angles to be set with ease using standard gauge blocks
These are very useful for manufacturing processes that require the highest standards of clamping accuracy at desired angles
