The holders produced in our company distinguish themselves by high durability and excellent mechanical resistance to fracture. Therefore we apply only the best quality materials.

On the basis of rich experience, we advise our customers whether to use surface hardened holders with a tough core (case-hardening steels) or heat treated holders with a complete through-hardened structure. Modified versions of holders from construction steels with additional coating for hardened surface are also possible (nitriding, hard chromium plating, ….).
