CUTTER M4x0.7

Humm DT thread milling cutter.

The specially designed geometry of the cutter allows for threading in full material without the need to drill a pilot hole. Due to low cutting resistance, Humm DT cutters are more durable than traditional machine taps and can be used on machines with lower power. An additional advantage of this series is the possibility of threading the bottom of the hole. Humm DT cutters are able to work in material with a hardness of up to 62 HRC.

  • Diameter: 3.1 mm
