Industrial TiCN Blue-Grey Coated HSSE M35 Machine Taps | 35° Spiral Flute 6H Taps for Stainless Steel
1. Introduction: The High-Hardness Specialist
Our DIN 371/376 HSS-E M35 TiCN Coated Spiral Flute Taps are engineered for the most demanding blind-hole tapping environments. By combining a 5% Cobalt (M35) substrate with an advanced Titanium Carbo-Nitride (TiCN) physical vapor deposition (PVD) coating, these taps achieve a superior balance of toughness and extreme surface hardness.
The 35° spiral flute geometry is optimized to mechanically lift chips out of blind holes, while the TiCN coating provides a harder, more abrasive-resistant surface than standard TiN, making it the definitive choice for tapping high-tensile steels and abrasive castings.

3. The TiCN (Titanium Carbo-Nitride) Advantage
-
Extreme Surface Hardness (approx 3000 HV): TiCN is significantly harder than TiN (2300 HV). This extra hardness is essential for resisting abrasive wear when tapping high-alloy steels and reinforced materials.
-
Low Friction & High Lubricity: The carbon content in TiCN provides a lower coefficient of friction than TiN, which reduces torque during the cutting process and prevents material adhesion (galling).
-
Enhanced Edge Strength: The TiCN coating reinforces the cutting edges, allowing for higher feed rates and more stable performance in interrupted cuts or high-torque applications.
4. Superior Industrial Applications
-
Hardened & Alloy Steels: Optimized for materials with tensile strengths up to 1200-1400 N/mm².
-
Stainless Steel & Inox: Exceptional performance in 304, 316, and duplex stainless steels where tool wear is usually rapid.
-
Abrasive Castings: Ideal for ductile iron and abrasive aluminum alloys where standard coatings fail prematurely.
-
Automated CNC Production: Specifically designed for high-speed machining centers (VMC/HMC) that demand long intervals between tool changes.
5. Manufacturing Excellence
-
HSS-M35 Cobalt Core: The 5% Cobalt substrate ensures that while the surface is extremely hard, the core remains tough enough to absorb the radial shock of high-speed tapping.
-
Fully Ground Construction: CNC-ground from solid hardened blanks to maintain 6H Tolerance and superior concentricity.
-
PVD Coating Precision: Utilizing advanced PVD technology to ensure a uniform TiCN layer that does not compromise the sharpness of the cutting edge.
6. Professional FAQ for Wholesalers
Q: When should I recommend TiCN over TiN coating?
A: Recommend TiCN for harder materials (steel > 800 N/mm²) or highly abrasive materials. It offers better wear resistance and a longer tool life in tougher alloys compared to TiN.
Q: Why use the DIN 371 Reinforced Shank for small sizes?
A: Small taps (M2-M10) face high torsional stress. The Reinforced Shank of DIN 371 provides the necessary rigidity to prevent "twisting" and snapping during high-speed automated cycles.
Q: Do you offer OEM laser marking?
A: Yes. Since 1997, we have provided high-definition Laser Marking on shanks (Logo + Size + HSSE + TiCN) and customized packaging in shockproof Rose-Boxes for global tool brands.
