Coating Machine Tap Stainless Steel Through and Blind Hole M3-12
High Performance Machine Taps for Professional Threading Applications
Our TiCN coated DIN 371 and DIN 376 machine taps are manufactured from premium HSSE (High Speed Steel with Cobalt) and enhanced with an advanced Titanium Carbon Nitride (TiCN) coating.
Combining the excellent toughness and heat resistance of HSSE material with the superior surface hardness of TiCN coating, these machine taps deliver outstanding cutting performance, longer tool life, and reliable thread quality in demanding machining environments.
They are designed for CNC machining, automatic production lines, and professional industrial applications where productivity and tool reliability are critical.

Product Features
Premium HSSE Cobalt Steel Material
Compared with standard HSS taps, HSSE taps contain cobalt elements that improve:
· Higher hot hardness during high-speed cutting
· Better wear resistance
· Improved cutting edge strength
· Greater resistance to thermal stress
· Longer tool life in demanding applications
The HSSE substrate provides excellent performance when machining harder and more challenging materials.
TiCN Coating for Enhanced Performance
The TiCN (Titanium Carbon Nitride) coating creates a hard and wear-resistant surface layer on the cutting edges.
Advantages of TiCN coating:
· Increased surface hardness
· Reduced friction between tool and workpiece
· Improved resistance against abrasion
· Reduced tendency of built-up edge formation
· Extended tool service life
The combination of HSSE material and TiCN coating makes these taps suitable for high-efficiency machining and long production cycles.
