Al Taps

Aluminum Alloys

For aluminum wrought alloys

Emuge offers a material specific cut tap for blind hole / bottoming (Enorm AL) and through hole / plug (Rekord B-AL) designs. In the machining of long-chipping aluminum, it is absolutely necessary to provide chip transport in an axial direction. In addition to the large rake angle, these tools are made with a reduced number of flutes so that there is even more room for the chips. This helps to avoid clogging of the flutes in cut threading operations.


  • GLT-8 Coating - Diamond-like, amorphous carbon coating
  • In a PVD process a coating thickness of 1-2 μm can be realized. The hardness is approx. 2,500 HV. This mono-layer coating is an excellent choice for the machining of non-ferrous metals and aluminum with a low silicon content (< 9% Si). Thanks to the low friction, material adhesion is drastically reduced.
