Goliath UN (BSC) HSS Circular Split Button Die

• HSS Circular Split Button Die
• HSS Button Dies (also known as Adjustable Dies) are designed for cutting external threads.
• They are used for threading rods, bolts, and studs, either by hand using a die stock, or by 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.
• British Standard Cycle (BSC) thread runs at 60º making it the equivalent of 60° UN, not 55° as used in BSW and BSF threads.
• All sizes 1/4" and larger use 26 TPI.
