3T90CM_TIN  Three flutes countersinks 90° Morse Taper Shank TiN coated

The TiN (Titanium nitride) coating, which has always been fascinating due to its shiny golden colour, was the first PVD coating to be used successfully in the industrial field. It is applied to chip-removing cutting tools.

Although over of the years research has made it possible to develop more complex coatings, TiN remains a very modern product and has a high performance in many fields.

3T90CM_TIALN  Three flutes countersinks 90° Morse Taper Shank TiAlN coated

Three flutes Countersink TiAlN coated, undergo a surface treatment to titanium nitride and aluminum that gives them special anti-friction and anti-friction properties and ensures less clogging of the cutting edges.

This feature makes it the best choice for the machining of non-ferrous metals, as well as abrasive materials and kneading.

They are also able to withstand very high processing temperatures (up to 800 °).

 

Its excellent thermal and chemical resistance allows for dry cutting and improvements in the performance of components subjected to high stresses. The high hardness of the coating provides excellent protection against abrasive wear and erosion.

Recommended Applications: Use dry.
