HSS Left Hand Circular Split Button Die
HSS Button Dies (Adjustable Dies) are designed for cutting external threads.
They are used for threading rods, bolts, and studs by hand using a die stock or machine using a floating die holder.
They also can be used to cut smaller or larger, than factory setting, by utilising the adjusting screws in the die holder.
Dies are manufactured with a thread chamfer to aid starting.
M2-HSS material provides increased wear resistance and superior thread accuracy.
The Metric Coarse angle of thread is 60 degrees.
The crest is flat and the thread has clearance at the root allowing external and internal threads to engage well.
A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
The major diameter of the external thread and pitch is specified by a simple numerical value (most commonly measured in millimetres).
