    Micron Lapping

    A gang of vise body gone through time consuming grinding process with micron accuracy on a CNC grinder

    Eye Inspection

    Each vise body will be put under the microscope to filter out unsatisfying cast iron bodies before assembling

    Smooth Movement

    Semi-hardened bright finished lead screws with precision turned threads to give them a solid & smooth feel when turning the vise handle


  • Pulling Mechanism

    With a heavy duty thrust bearing pack located on the rear of the vise body, the clamping force is a pulled rather than pushed motion. This pulling mechanism would reduce stress and minimize deflection on the vise body when applying high clamping pressure.

  • Minimum Jaw Lift

    Every machinist is afraid of the term "jaw lift" when associated with a vise. The 690X offers key improvements to prevent jaw lifting by using a 45 degree wedge and a pivoting ground finished steel hemisphere in a milled pocket to hold down the movable jaw. This results a minimal amount of jaw lift applying under pressure when comparing to other highly regarded go-to branded vises.

  • 6.25" Opening Capacity

    6.25" Opening capacity allows more clamping in a small footprint. With the 5 mounting thru holes with 5" spacing on the vise bed would allow more vises mounting side by side on a milling table.

  • Hardened Vise Bed / Jaw Plate

    -Vise jaw plate threads and spacing meets the industry standards
    - Bedways are flame hardened to 45 HRc and jaw plate hardened to 54 HRc
    - Bed height and the distance between keyway and stationary jaw remains the same and meets the industry standards
    - Bed height matched to 2.875" +/- 0.0005"
    - Vises' bed parallel to base within 0.0005"
    - Fixed Jaw perpendicular to bed within 0.0005"
    - Fixed jaw parallel to vise's keyway within +/- 0.0005"

  • Brush Seal

    Continuing from the design feature in 690V vises, a brush on both end of spindle nut to wipe off chips to improve & extend the lead screw life.

  • Large Chip Evacuation

    2 large chip evacuation slots are strategically located on each side of the vise to allow a good flow of chips while at the same time not diminishing the vise’s body strength. The vise body is also reinforced with a thicker rib to support the pulling mechanism when clamping

  • Matching Bed Heights

    When ordering multiple vises, the bed heights will be matched within .0001" at no additional cost (subject to inventory stock availability)
