Finding the Right Product

Yes, our local sales representatives have demo kits available. Check the Factory Reps page to find a representative near you.

All of our top tooling kits can fit on either the 96mm or 52mm RockLock system. The appropriate top tooling setup for you will depend on your stock size and application. You can use the 3D Compatibility Tool to see what top tooling options fit your machine table. Each product page also includes a link to a 3D model: Use this in programming to test for interference.

Please contact for all tombstone inquiries.

Finding the appropriate RockLock plates depends on getting a table drawing for your machine. (You can also use our 3D Compatibility Tool to see what RockLocks fit on a list of common machine tables.) From your machine table drawing, we can determine whether your machine would have direct fit or require modification to our standard products. The mounting information for our standard product can be found in our catalog or on each RockLock product page. If you cannot figure out the necessary mounting information, please contact

Product Information

Yes, pull studs can be machined directly into your existing fixturing. Sub-plates can be fabricated to adapt your existing tooling to the RockLock system.

The self-centering repeatability of the vise is less than 0.0005″ (0.0127 mm).

‘Soft jaws’ (in steel or aluminum) are machinable, meant to be cut to the profile of the workpiece for secondary operations.

The hardness of the jaw is 55 HRC.

A ‘Master Jaw’ or ‘Hard Jaw’ is the hardened steel jaw with the dovetail and serrated teeth that comes standard with our vises.

The hardness of the vise body is 40 HRC.

All 5th Axis products utilize a 45 degree dovetail. We also offer picatinny fixtures in the Dovetail Fixture product section.

A dovetail fixture holds the stock with dovetail cuts. Our dovetail fixtures have a very small profile, which allows more accessibility to the stock material. All of 5th Axis dovetail angles are 45 degree, and there is dovetail stock prep document for each fixture.

Poka Yoke is a Japanese term for mistake-proof. We offer Poka Yoke pull studs to prevent operators from misloading vises and fixtures.

Top tooling generally includes anything that mounts to the RockLock system. If it includes pull studs, it’s top tooling. We offer a variety of top tooling setups, ranging from self-centering vises to multi-fixture pyramids and more in the Products section.
