If you’re thinking of replacing your Vice Jaws, the first thing to know is….not all Vice Jaws are equal! This page will (hopefully) explain why our ViceWorks Hard Jaws are a cut above the rest (literally).

The Knurl 

ViceWorks Hard Jaws have a ‘File-Cut’ knurl

This is one of the most important elements and is the principle reason why our Jaws are superior. The image below shows a ViceWorks Jaw. 

The process we have developed produces a knurl that ‘bites’ into the material being held… due to its  ‘file-cut’ pattern. This knurl can only be achieved through a process of ‘cutting’ the face of the jaw in a linear way, using a single point cutting tool.  This achieves a superior knurl.

Other Jaws 

The images below shows the ‘knurl’ on other Jaws…as supplied by most manufacturers. As you may see, these Jaws are nothing more than groves in the face which provide no ‘Bite’, unlike our ViceWorks Hard Jaws. 

Material

ViceWorks Hard Jaws are made from cold drawn Engineering Steel, fully machined and Case Hardened.

Hardness

Our Jaws are Case Hardened to a Rockwell value of 56 to 58 (HRC).

Case Hardening ensures a strong yet wear resistant Vice Jaw, far superior to the 'mass produced' products which have swamped the market for decades. 

Our Hard Jaws are what they say on the tin, ‘Hard’. 

Precise

All our Jaws are CNC machined to ensure a repeatable and precise product.
