M10 Machine Tap DIN 376 Form C HSSE TiN 40° Helix 6H

In a busy machine shop, a machinist picks up this M10 tap to thread through holes in a stainless steel flange. The 40° right-hand helix pulls chips backward, preventing clogging and ensuring clean, accurate threads in one pass. The TiN coating reduces friction and heat, extending tool life even in tough materials like alloy steel and cast iron.

Key specifications

• Thread size: M10 × 1.5 mm (metric coarse)
• Standard: DIN 376, Form C (2–3 threads lead)
• Tolerance class: 6H
• Material: HSSE (high-speed steel with cobalt)
• Coating: Titanium Nitride (TiN)
• Helix angle: 40° right-hand
• Cutting direction: right-hand cut
• Shank: cylindrical with square drive
• Overall length: 100 mm; thread length: 20 mm
• Shank diameter: 7 mm; square drive: 5.5 mm

Why choose it

The 40° helix is ideal for through holes, efficiently evacuating chips behind the cutting edge. HSSE with cobalt offers superior heat resistance compared to standard HSS, while TiN coating further enhances wear resistance. This combination delivers consistent performance and a longer service life in production environments.

Ideal use cases

• Threading through holes in steel, stainless steel, cast iron, and non-ferrous metals
• General machining, maintenance, and repair workshops
• CNC machining centers and manual tapping operations

Good to know

Form C taps have a 2–3 thread chamfer, balancing ease of starting with thread depth. The 6H tolerance class ensures a standard fit for metric coarse threads. Always use appropriate cutting fluid and correct tapping speeds for best results.
