1. Dimensional Overview: Material & Coating Synergy

Our TiCN (Titanium Carbo-Nitride) coated taps represent a significant upgrade over standard TiN. By adding Carbon to the Titanium-Nitride matrix, we achieve a surface that is both harder and more lubricious.

• HSS-E M35 Substrate: Forged with 5% Cobalt, providing the necessary "Red Hardness" to maintain a sharp edge even when friction temperatures reach 600°C.

• TiCN PVD Coating: Boasting a surface hardness of approximately 3,000 HV, the blue-grey TiCN layer acts as a physical barrier against abrasive wear and cold welding (material adhesion).

2. Geometric Precision: The 35° Helix Advantage

• Efficient Chip Lift: Specifically designed for Blind Holes. The 35° right-hand spiral acts as a mechanical elevator, pulling long, stringy chips upward and out of the hole to prevent "chip packing" and tap breakage.
• 6H Tolerance Class: Every tap is CNC-ground to meet strict ISO 2/6H standards, ensuring high-precision thread fit for automotive, aerospace, and medical components.

3. Technical Specifications (M2 - M42 Full Range)

4. Application Perspective: Mastering Difficult Materials

• High-Tensile Steels: Ideal for materials with tensile strengths between 800 and 1,200 N/mm², such as alloy steels and tool steels.

• Stainless Steel Specialist: The low-friction TiCN layer prevents the "sticky" behavior of 304 and 316 stainless steels, reducing torque spikes.

• Cast Iron & Abrasive Materials: The extreme surface hardness protects the cutting edge from the abrasive particles found in ductile and gray cast irons.

5. Supply Chain & Quality Assurance

• Fully Ground Process: CNC-ground from solid hardened blanks for superior concentricity and surface finish.

• Industrial Packaging: Each tap is housed in a shockproof Rose-Box plastic case with high-viscosity anti-rust oil for a 36-month shelf life.

• OEM & Customization: Since 1997, we have supported B2B wholesalers with High-Definition Laser Marking and private label packaging to help build local brand equity.

6. Professional FAQ for Buyers

Q: Why choose TiCN over TiN for hardened steel?

A: TiCN is roughly 30% harder than TiN and offers better impact resistance. In harder materials or interrupted cuts, TiCN provides superior edge retention and lower "cost-per-hole."

Q: What is the difference between DIN 371 and DIN 376?

A: DIN 371 (M2-M10) features a reinforced shank for maximum torsional rigidity in small-hole tapping. DIN 376 (M12-M42) has a reduced shank, allowing for deeper tapping without shank interference.

Q: Can these be used for hand tapping?

A: While possible, these are high-performance Machine Taps optimized for the rigid alignment and constant speed of CNC Machining Centers.
