BaerCoil® Taps - Surface Treatments

Nitriding
Increase of nitrogene of the tools surface in a tenifer bath at approximately 550°C, 0.02 mm depth.
Hardness = 1100 HV.
Improved friction properties and an increased wearing resistance.

VAP Stream oxydated
In a water steam atmosphere of 530°C we manufacture an oxyde layer which prevents cold welding extensively.

Surface Treatments Service for every Threading Tool

We can manufacture every threading tools with a surface treatment - please inquire

	TIN coating (Titanium nitrade) Titanium, evaporated at approximately 500°C. Hardness = 1100 HV Coat thickness 0.002 mm Extremely wear- resp. abraison-resistant. Very good riction properties.
	TiCN coating Similar procedure to the TIN coaring. Titanium-carbon-nitride coating, vapour-deposited in the PVD process at approximately 500°C. Hardness = 3000 HB Coat thickness = 0.002 - 0.003 mm In comparision to the TIN coating the tool life is prolonged once more and the cutting speed is increased.
