KURT: Kurt Expands DX Vise Line with DX8 8″ Vise

New DX8 CrossOver® vise to bring the same benchmark DX-series vise features to the 8-inch vise platform


The Kurt DX8 CrossOver® vise is the newest and largest vise in the DX CrossOver® vise family. We’ve combined the best features of the Kurt D810 and Kurt 3800V vises into a single vise with state-of-the-art features that set a new standard in precision flatness, parallelism and repeatability.

DX8 CrossOver features new body design

The premium, one-piece body design, now standard on all our general-purpose vises was designed using Finite Element Analysis and has 30% Less horizontal (push back) deflection than previous DX models. Less vise-body deflection means more stability than a bolt-on design allows and a lifetime of dimensional precision. It’s the same design we’ve used successfully on 3600V and 3800V models for years.

The DX8 CrossOver® vise features the same bed height and keyway to the stationary jaw face as the D810 and a redesigned nut with lighter weight, a new brush seal design and a larger, stronger bearing pack that’s more durable than previous vise designs.



KURT: 45-Degree Pyramid Workholding Bundles

NEW 45-Degree Pyramid Workholding Bundles With Standard Kurt Vises For 5 Axis Machining.

The Kurt platform was so well received by the machining industry in 2019, that they have developed a pre-engineered pyramid platform which is standard and accommodates 12 different vise models. These convenient configurations come bundled with the 45-degree pyramid along with 3 Kurt vises ready for mounting to machine table and handle parts from 2” up to 7”.

The Kurt pyramid workholding bundles facilitate clamping of three individual components in one fixture and completed in a single setup. And provide maximum access to all machined surfaces and allows for enhanced spindle and cutting tool clearance.

Kurt vises matched for the pyramid include self-centering and dovetail models: HP420, HP420C, HP420D, HP440, HP440C, HP440D, HP460, HP460C, HP460D, SCMX250, SCMX425, DTR20. Each bundle package comes complete with 45-degree pyramid, 3 vises mounted, and optional base plate for final mounting on machine table. Options include soft jaws for machining odd shaped profiles into the jaws, hard jaws, and a riser base model for even more part clearance.

Please contact us for more information on the new Pyramid Workholding systems.



KURT CarvLock® CTHDL Manual Cluster Towers

Kurt® Workholding’s CarvLock® CTHDL manual cluster towers are designed for use with mid-size and larger CNC machining centers, including horizontal and vertical machining centers with a fourth axis and/or indexable tables. These manually operated, eight station vise towers are capable of producing up to 7,460 lbs. of clamping force at just 70 ft-lbs. of torque. They provide exceptional workpiece immobility while dampening cutter-induced vibration. Ductile iron column construction ensures strength, rigidity, and long term accuracy.

A self-adjusting holding block on either the front jaw or back jaw allows for easy clamping of same or differently-sized parts. To provide faster operation, an adjustable pre-load feature reduces the number of handle turns required for opening and closing the clamping stations.

With eighteen CTHDL models available, with 4” or 6” jaws, it’s easy to find the right manual cluster tower for your unique workholding needs. Order the CarvLock® CTHDL cluster tower your application requires, or contact Kurt Workholding for more information.

See individual product listings for additional information and specifications. All models are protected by Kurt’s Lifetime Iron Clad Warranty.

KURT Workholding: Vertical Machining Center Concepts

Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top of a workpiece.

Vertical Machining Benefits
There are many benefits associated with vertical machining, some of which include:

  • Infinite part shape possibilities due to the 3, 4 or 5 axis capabilities
  • Temperature stability
  • Durability and reliability
  • On-board probing
  • User-friendly CNC controls
  • Efficient and cost-effective pallet changers

Vertical Machining Center Applications
Depending on the job we offer a variety of diverse types of workholding to fit all your vertical machining needs.

KURT Workholding: Horizontal Machining Center Concepts

The Horizontal Machining Center (HMC) concept favours uninterrupted production work. One reason for this is that the horizontal position encourages chips to fall away, so they don’t have to be cleared from the table. More significantly, the horizontal design allows a two-pallet machine to be incorporated into a space-efficient machine. To save time, work can be loaded on one pallet of a horizontal machining center while machining occurs on the other pallet.

Horizontal Machining Center Applications

There are many benefits associated with horizontal machining, some of which include:

  • Shorter processing time per part – With horizontals’ ability to swap pallets, there is no significant delay between machining cycles for job change-over. Plus, on the tombstone fixtures, various pieces can be completed in a single cycle.
  • Lower prices – Horizontal machining has brought down the overall price per part quoted to customers.
  • Three-side machining – The B axis allows three faces of the part to be reached in one cycle. Parts with similar features can also be machined in the same cycle to ensure accuracy.
  • Complex part machining – Complex parts can now be machined more quickly and cost-effectively than ever before.
  • Advanced tooling platform – Horizontal machining centers take advantage of the latest in cutting tool technology.
  • Multi-customer Response – The ability to run multiple jobs on alternating pallets of the same machine allows use to fill orders for two customers in the same shift.


Depending on the job we offer a variety of diverse types of horizontal workholding to fit all your machining needs.
