HSS threading die N5120

For trouble-free cutting of external threads with an unsurpassed thread flank and cutting edge finish. Dies with spiral entry: a spiral entry results in a free flow of chips ahead of the die and a reduction in the cutting torque. Blocking of the clearance holes by chips is avoided. This results in an improved surface finish on the cut threads and a longer die life. Hence dies for machine use must be ordered with spiral entry.
