## Description

Full sizes included: 3 mm 4 mm 5 mm 6 mm 7 mm 8 mm 10 mm 11 mm 12 mm. Carbon Steel Hand Taps may also be used to thread mild steels. Taper Style: Starts the thread square with the workpiece. Plug Style: Generally used in thru holes. Bottom Style: Generate the thread to the bottom of the hole. About Carbon Round Adjustable Dies: For re-threading, a Carbon Steel Round Adjustable Die is desired for improved wear life. Round Dies are chamfered on both faces. 1 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.
