About Titanium Nitride Tap

Titanium Nitride Tap

STEAM TEMPERING & NITRIDING. Nitriding hardens the taps surface skin and gives a grey/black appearance. It extends tap life when used on abrasive materials such as Copper, Aluminium alloys and Plastics, but it can make the tap brittle and more prone to breakage. Steam Tempering gives a blue/black finish. It causes minute imperfections on the surface of the tap. These cause the tapping lubricant to be retained more readily, reducing friction and the possibility of cold welding. This helps the tap to cope with both mild and stainless steels. Both above processes are normally only required for Spiral point and Spiral flute taps when the work piece material requires them. These taps are known as Steam tempered and nitrided and have a blue/black finish. Titanium nitrided taps. TITANIUM NITRIDE (Tin) This is a gold coloured coating only a few microns thick which is not metallic so reduces the chance of cold welding. It is applied by vapour deposition using special purpose machines. It imparts to the tool a surface hardness of around 80-85 Rockwell. It also imparts a good abrasive resistance and subsequent decrease in friction between the tool and the work piece. This can allow tapping at higher speeds. Suitable for most stainless steels. The process can increase the price of a tap significantly. When the tap is reground the coating will be removed. This coating is more appropriate to Fluteless taps than steam tempering and nitriding. TITANIUM CARBIDE NITRIDING (TiCn) This coating is applied to the tool in the same way as Tin, and gives a silver/grey finish. It has the same qualities as Tin coating, but more so. It is equally more expensive. Suitable for very abrasive and high tensile materials. We would be happy to advise you the best tap and coating for your job.   

Exceptional Durability and Performance

The TiN coating on these taps delivers outstanding resistance to wear, corrosion, and heat, extending tool life significantly compared to uncoated models. Their high-speed cutting capability, precision thread pitch, and low cutting force requirement make them ideal for high-performance threading operations. With ISO standard tolerances and customizable options, users receive reliable threading and consistent results even with heavy-duty applications.


Versatile Application and Customization

Designed for use in various industries, these taps accommodate both manual and machine-based threading tasks. Customers can select thread pitch, blade size, cutter type, and packaging options to suit project requirements. Their compatibility with standard drilling and tapping machines, coupled with resistance to high temperatures and torque, ensures they meet demanding operational needs across multiple sectors.
