The FV4 is a 4" compact all steel construction vise 100% designed and made in the USA for existing fixture plates with 1.25" center to center hole spacing. It is useful for holding oversized parts, several parts in a high density workholding configuration, and fits machines from the Tormach 440, two on a  Pierson Pallet, welding setups, to full sized VMCs

Accessories Coming Soon (maybe 2024 in this order)

  • Dual station block for FV4 (will also function as updated fixed jaw)

  • Side finger slots to handle moving jaw easier

  • Workstops

  • 6" long Talon/Anderson jaw for FV4

  • More hardened stepped jaws

  • 1018 steel softjaws


Eta later

  • Full length vise base with dual station capability

  • Automation upgrades


  • 100% steel construction

  • Hold parts larger than conventional vises

  • Moving jaw is spring loaded so you don't have to retract the jaw by hand. It also preloads the jaw into the base, preventing ingress of chips. 

  • Serrated teeth allow for semi coarse position (travel range of 1.7"). This means you have to unbolt and adjust less when setting up.

  • The wedge itself has a travel range of 1/8" (for final clamping)

  • Dual station capability

  • Compatible with fixture plates with 1.25" bore/thread spacing (SMW, Tosa Tool (wide body bases only), etc)

  • High stress components made from 4140 PH high strength alloy steel

  • Ground faces. The bases of the fixed jaw and moving jaw are ground to match each other. It is designed to be a reference in Z for parallels or soft jaws. Bases are also ground to 0.750" so that long work pieces can be held on multiple vises.

  • Base is made from 4140 alloy steel and hardened to Rockwell C 40+.

  • Includes a standard bolt pattern for soft jaws (the same as a Kurt DX4)

  • These may be upgradeable with a low profile pneumatic/hydraulic autocloser in the future

  • Jack screws included (to make it easy to remove any components with pins)

  • Made in the USA

  • Clamping force:

    • 1600 lbf @ 20 ft-lbs

    • 3200 lbf @ 30 ft-lbs​

    • 4400 lbf @ 40 ft-lbs (nearly identical to a Kurt DX4)
