TiN-coated threading tools: efficiency and wear protection in practice
TiN-coated threading tools: efficiency and wear protection in practice
In modern machining, a small detail often makes the difference when it comes to efficiency, cost-effectiveness, and process reliability: the surface coating of threading tools. Especially in thread cutting, where precision meets hardness, the right coating plays a key role. The TiN coating (titanium nitride) helps you extend tool life and keep processes stable—whether in series production or for special requirements. To help you make full use of this potential, we at VÖLKEL offer the right threading tools from a single source.
What is a TiN coating on threading tools?
The TiN coating, short for titanium nitride, is a thin, hard layer applied to taps, thread formers, and other threading tools. TiN is created using a physical or chemical vapor deposition process, such as PVD or CVD, in which titanium and nitrogen react in a controlled chamber and deposit onto the tool surface. The result is a uniform, typically golden-yellow protective layer with very robust properties.
Typical challenges without a coating
Without suitable surface treatment, threading tools reach their limits more quickly—especially in harder materials or at higher cutting parameters. Common issues include:
- Rapid wear due to abrasive cutting conditions
- Increased friction between the tool and the workpiece
- Thermal load and resulting tool damage
- Built-up edge/cold welding in the thread flank
In practice, this means shorter tool life, higher tooling costs, and noticeably reduced process stability.
The solution: TiN-coated threading tools from VÖLKEL
We offer a wide selection of TiN-coated threading tools that are available from stock as standard. This mainly includes machine taps in numerous standards and sizes.
Benefits of TiN coating at a glance
- Higher surface hardness
TiN makes the tool surface significantly more resistant and reduces wear—especially in recurring applications. - Lower friction and less heat
The tool runs more smoothly through the material, the load is reduced, and the risk of cold welding is significantly lower. - Longer tool life and better cost-efficiency
In many cases, the tool lasts noticeably longer. That means fewer tool changes, less machine downtime, and lower cost per thread. - Easy identification in everyday use
The golden TiN surface makes it easy to quickly identify the tool on the shelf and on the shop floor.
Applications in manufacturing
TiN coatings are used very broadly in practice: from thread cutting in steels and cast iron to non-ferrous metals such as brass. TiN is particularly useful wherever you need higher cutting speeds, less tool wear, and stable, reliable thread quality.
Typical applications for TiN-coated threading tools include:
- Series production with high volumes
- CNC machining at higher spindle speeds
- Materials with medium to high hardness
- Interrupted cuts
- Repair and maintenance work where process reliability is critical
