Torque Handle

The Kurt Torque Handle provides repeatable clamping for small delicate parts. The Torque Handle gives you a precise feel while providing an audible 'click'. The small 10-3/4" overall length will not interfere with most table set ups and the steel construction will give you the versatility and reliability demanded by today's modern machine shops. A set screw allows your Torque Handle to become an integral part of your vise, and by adding a hex extension you can use it on 4" and 8" vises.

  • Four Torque Setting Positions:
    1. 6 Torque Ft Lbs.
    2. 8 Torque Ft Lbs.
    3. 10 Torque Ft Lbs.
    4. 20 Torque Ft Lbs.
Parallel Keeper
Place your parallels in the vise against the jaws. Take the Parallel Keeper, squeeze it together and place it inside the parallels. Release the Parallel Keeper, it will push against the parallels, holding them against the jaws of the vise. It's that simple. Opens to 6". Your new revolutionary labor savor, your "machinist's third hand", is at work, saving part change time.
Vise Screw Hex Extensions
  • Vise screw hex extensions become useful when the vises are mounted on large machines where extending the hex will allow better access, or to extend the handle outside a table guard on your mill, so you do not have to remove the handle during each clamping.
  • Hex extensions will allow a 6" handle to be used on a 4" or 8" Kurt Vise
