What to Look for When Buying Used Kurt Workholding
Kurt vises are built to last decades, and used units regularly deliver years of additional service. The AngLock design and ductile iron construction hold up well, but wear points exist.
Check the screw, nut, and bearing pack. Turn the handle through full travel and feel for gritty spots, binding, or excessive play. A worn leadscrew or nut produces inconsistent clamping force. On DX6 models the bearing pack is larger, but older D675 and D688 units may show wear. Rebuild kits are available for most D-series vises.
Inspect the stationary jaw for deflection and damage. On bolted-jaw models (D675, D688, D810), check the jaw-to-body interface for chips, corrosion, or looseness. The DX6 addresses this with a cast-on stationary jaw that eliminates the bolted joint. Verify jaw faces are flat and parallel with a precision indicator.
Verify the AngLock mechanism and jaw lift. Clamp a test piece and confirm the movable jaw seats downward with no measurable lift. If the part rises under force, the AngLock segment or mating surfaces may be worn. On VersatileLock (3600 series) vises, pull-type clamping should produce noticeably stiffer holding than push-type models.
Kurt Single-Station CNC Vises
DX CrossOver Series
The DX6 is Kurt's current 6" vise platform, a direct replacement for the D688 with a cast-on stationary jaw, narrower body for higher table density, and 9" jaw opening. The DX4 is the 4" version. Hydraulic variants (DX6H, DX6H-SD) accept Kurt pump systems for automated cell integration.
D-Series Legacy Vises
The D675 (6" jaws, 7.5" opening) and D688 (6" jaws, 8.8" opening) are among the most widely traded used vises in North America. The D810 provides 8" jaws with 10" opening. Smaller models include the D30, D40, D50, and D60. All D-series vises use the AngLock push-type design and remain fully parts-supported.
VersatileLock (3600 Series)
The 3600V is widely regarded as Kurt's most rigid vise. The one-piece body and stationary jaw casting with pull-type clamping reduces jaw deflection by at least 80%. Available in 4" (3400V), 6" (3600V), and 8" (3800V) with hydraulic (H) and angular (A) variants. VersatileLock vises mount back-to-back as tombstone assemblies for HMCs.
Kurt Multi-Station & Production Vises
The HD690 and HD691 are heavy-duty single-station vises with 9" openings. HDL4/HDL6 double-station vises (with HDLM machinable-jaw variants) deliver high-density clamping for VMC setups. The DoubleLock line (DL430, DL640, DL800) provides dual independent stations in one body. XL6/XL8 extra-capacity vises handle oversized workpieces. PT-series vises (PT400A, PT600A, PT800A) mount to pallet-changer interfaces for automated production.
Kurt 5-Axis & Modular Workholding
MaxLock HP Self-Centering Vises
The MaxLock HP series (HP420, HP440, HP460) delivers self-centering 5-axis clamping with serrated, dovetail, or machinable jaw options. Pre-hardened 4140 steel with repeatability within plus or minus 0.0005" in 5", 7", and 9" lengths, supporting I.D. and O.D. clamping.
DoveLock Dovetail 5-Axis Vises
The DoveLock line (DT20, DTR10, DTR20) uses dovetail clamping for aggressive 5-axis machining. Pre-hardened 4140 steel, with reversible jaw models (DTR10, DTR20) accommodating a broad range of widths.
Towers, Tombstones & Modular Systems
Kurt CarvLock cluster towers (CTHDL series) provide eight-station clamping for HMCs with up to 7,460 lbs. of force. ToolBlox tombstones offer pre-drilled mounting surfaces for custom fixturing. SeraLock foundations paired with WedgeLock and MoveLock modules deliver reconfigurable workholding that adapts to changing part sizes without dedicated fixtures.

Frequently Asked Questions About Used Kurt Workholding
Are used Kurt vises reliable?
Yes. Kurt vises are manufactured from 80,000 PSI ductile iron with precision-machined components. The AngLock design has been proven across decades of production use, and rebuild kits are available for most D-series models.
What is the difference between the Kurt D688 and DX6?
The DX6 CrossOver is Kurt's direct replacement for the D688. Both have 6" jaws and the same bed height for easy retrofits. The DX6 adds a cast-on stationary jaw for less deflection, a narrower body for higher table density, and a 9" opening (versus 8.8").
What should I inspect before buying a used Kurt vise?
Focus on four areas: the leadscrew and nut assembly (feel for wear or binding), the stationary jaw interface (check for damage on bolted-jaw models), the AngLock mechanism (verify no jaw lift during clamping), and overall body condition (cracks, corrosion, or warping).
What Kurt models hold their value best?
The DX6, D688, and 3600V VersatileLock maintain the strongest resale values. MaxLock HP 5-axis vises and CarvLock towers also hold well. Call (844) 478-8181 for current valuations.
Can I still get parts for older Kurt vises?
Yes. Kurt manufactures rebuild kits for the D30, D40, D50, D60, D675, D688, and D810. Replacement leadscrews, nuts, handles, jaw sets, and AngLock segments are available through authorized distributors.
