Drill America DWT Series Qualtech High-Speed Steel Round Adjustable Threading Die, 1" Diameter, 1/2"-28 Size (Pack of 1)
Drill America DWT Series Qualtech High-Speed Steel round adjustable die is desired for improved wear life. Round Dies are 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 die is use in a machine holder the adjusting screw can be removed and adjustment made by the adjusting screws in the holder.
