1-1/2" NPT 3" OD HSS Round Adjustable Pipe Die DWTH3-112NPT

Size: 1-1/2-11-1/2 NPT, Material: High Speed Steel, Finish: Uncoated (Bright), Style: Round Die - NPT, Die OD: 3, 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. Size: 1-1/2"-11-1/2" NPT
