HSS, Fractional, Standard 3" OD 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
