      •  *While removing the collar, the feed rate should be increased at the end of the process, approx. 900 mm/min.
      •  These are recommended values and they may vary significantly, depending on the type of material, material
             thickness, lubrication, etc. For thread forming, we recommend our cutting oil. If you use an emulsion, it should contain
            at least 8-10% grease.
