Features:

1. **Cobalt Coating**: Coating a layer of hard cobalt on the tap surface significantly improves its wear and heat resistance, reduces friction and heat build-up during the cutting process, thus prolonging the service life of the tap and improving the work efficiency, and also reduces the risk of wear or breakage of the tap due to overheating.

2. **Extrusion moulding**: Extrusion tap adopts the principle of plastic deformation to process the threads without generating chips, which is especially suitable for thin-walled materials and materials with high strength but good toughness, and the threads formed have high precision and good surface quality.

3. **TIN Coating**: TIN here may refer to "Titanium Nitride" coating, which is a commonly used PVD or CVD coating technology, which can further enhance the tap surface hardness, oxidation resistance and anti-bonding, reduce the cutting force, so that the tap in high-speed, high-temperature, high-load tapping conditions can still maintain excellent performance. performance.
