The time consuming job of grinding thread forms is entirely eliminated with the use of these Criterion Threading tools. Based on the constant clearance design, they retain their true thread form even after 180 degree of the tool has been ground away. Top face grinding resharpens but will not alter the form or clearance.
Rolling dies exploit the plasticity of metal to form screws and serrations by rolling rather than cutting. This process maintains the integrity of the material by preventing damage to it structurally. The absense of cutting also makes this a high-speed process.
Consequently, many forms, serrations, and splines used in the manufacture of automotive parts are now made using rolling dies.
OSG is the world leader in the production of rolling dies renowned for their high quality and level of technology.
