Drill America m4 x 0.7 x 13/16 in. O.D. High Speed Steel Round Threading Adjustable Die

Drill America High Speed Steel Round Adjustable Dies are perfect for use in making new threads or re-threading existing threads. These high-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Round Dies are chamfered on both faces. 1 side has a 2 to 3 thread chamfer for threading, the other side has a 1 in. to 1-1/2 in. 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.
