M2 DIN 371C 6HX Thread Forming Tap HSSE-PM TiN Coated Straight Flute Through Hole

In precision machining shops, when producing threaded holes in tough materials like stainless steel or high-strength steel, this M2 thread forming tap delivers reliable performance. The cold forming process creates threads without producing chips, resulting in stronger, more accurate threads with excellent surface finish. Ideal for through-hole applications in components requiring high thread strength and durability.

Key specifications

• Thread size: M2 x 0.4 mm, metric coarse thread
• Tolerance class: 6HX (for metric threads, suitable for normal engagement length)
• Tool standard: DIN 371C (reinforced shank for improved stability)
• Material: HSSE-PM (powder metallurgy high-speed steel with cobalt) for high wear resistance and toughness
• Coating: TiN (titanium nitride) for reduced friction and extended tool life
• Flute type: Straight flute (SR) for through-hole threading
• Chamfer: Type C (2-3 threads lead-in) for gradual thread forming
• Overall length: 45 mm, shank diameter: 2.8 mm, square drive: 2.1 mm
• Suitable for materials up to 1200 N/mm² tensile strength

Why choose it

The thread forming process displaces material rather than cutting it, producing threads with superior strength and fatigue resistance. The HSSE-PM substrate with TiN coating ensures high productivity and long tool life, even in demanding applications. The DIN 371C reinforced shank provides excellent rigidity, reducing vibration and improving thread quality.

Ideal use cases

• Threading through holes in steel, stainless steel, cast iron, and non-ferrous metals
• Components requiring high thread strength and durability
• Production environments where chip-free threading is preferred

Good to know

Thread forming taps require a pre-drilled hole of precise diameter; consult manufacturer's charts for correct drill size. Suitable for use with external coolant. This tap is part of the WGN series, known for high performance in demanding materials.
