Powerhold Hard Serrated Top Jaws

Powerhold Hard Serrated Top Jaws
  • If the chuck is to be used for bar work infrequently, and most of your workpieces are rough forgings or castings, standard hard serrated top jaws may be ideal for your workholding needs. They can be positioned in the master jaw to hold any diameter within their range. Because the casting or forging surface to be gripped is rough, this type of serrated jaw is used to penetrate the actual gripping surface.
