1/4"-40 X 1" OD HSS Round Adjustable Die DWTSR1-1440

Size: 1/4-40, Material: High Speed Steel, Finish: Uncoated (Bright), Style: Round Die, Die OD: 1, Cutting Direction: Right Hand For threading, a 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 dies are used in a machine holder the adjusting screw can be removed and adjustment made by the adjusting screws in the holder
