Specification

Long machine nut screw tap with overrun shaft for cutting nuts for metric threads in steel up to a strength of 800 N/mm².

Long service life

Very long threaded start (approx. 2/3 of the thread length) and up to 4x more teeth compared to conventional machine taps

Specially developed for machining nuts

The groove and thread geometry has been specially designed for machining nuts.

Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable

Notice

Sufficient coolant and lubricant must be added when cutting threads.

Application

Instructions

Before reversing the screw tap, the entire point of the tool must be removed from the drill hole. Failure to do so may cause cutting edges to chip or the tool to break.

Key
v_c = cutting speed [m/min]
f = feed [mm/r]
n = rotation speed [rpm]
The suggested cutting values are reference values and must be adapted to the respective conditions.
