Powerhold Aluminum Wrap Around Top Jaws


Powerhold Aluminum Wrap Around Top Jaws
  • Our aluminum wraparound type top jaws are constructed of 6061-T6 high strength aluminum. Like standard soft blanks, these aluminum jaws are designed for secondary operations in which a serrated top jaw would mar the pre-machined surface. Because of their wide applicability, and the ease with which they may be bored to size, these aluminum top jaws are among the most popular we produce.
