HSS Round Dies

HSS Round Dies

  • For use in making new threads or re-threading existing threads
  • Good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • Round die is chamfered on both faces
  • One side has a 2 to 3 thread chamfer for threading, the other side has a 1 to 1-1/2 thread chamfer for threading close to a shoulder
  • Adjustment is obtained by a fine pitch screw which forces the sides of the die apart, or allows them to spring together
  • The slot is beveled so that when the dies are used in a machine holder the adjusting screw can be removed and adjustment made by the adjusting screws in the holder
