TECWERK machine tap DIN 371C M6 x 1 HSS‑Co — universal machine tap with 40° helix

The TECWERK machine tap DIN 371C M6 x 1 HSS‑Co is a universal right‑hand spiral machine tap designed for producing M6 x 1 metric ISO blind threads in steels, stainless steels, spheroidal cast iron and non‑ferrous metals.

• Universal HSS‑Co, Form C
• Vapour‑coated finish, green ring
• 40° right‑hand spiral for blind holes
• ISO2 (6H) tolerance for precise fit

High‑performance threading that extends tool life and uptime

The cobalt‑alloy HSS‑Co construction combines toughness and hardness to resist thermal softening under intermittent machine loads, resulting in improved tool life and fewer tool changes. The vapour‑coated surface reduces friction at the cutting edge and enhances wear resistance, which translates into longer production runs and more predictable maintenance intervals. As a universal machine tap in Form C, it balances cutting aggressiveness and stability, making it suitable for mixed production environments where operators need a dependable thread‑making tool for both mild and demanding materials.

Geometry engineered to reduce breakage and improve thread quality

The 40° right‑hand helix and flank‑honing (flank honing) work together to improve chip control and reduce cutting forces when forming threads in blind bores. The spiral geometry moves chips away from the thread root, lowering the risk of chip packing in blind holes and helping to produce a cleaner flank and improved surface finish. Compliance with DIN 13 sheet 1 and the ISO2 (6H) tolerance field ensures consistent flank fit and interchangeability of threaded parts, which is essential for assemblies requiring reliable preloads and repeatable mechanical behaviour.

Practical features for easy integration and consistent production

With a nominal designation of M6 x 1 and a shank Ø 6 mm, this universal tap fits standard machine tool holders and collets without special adaptors, simplifying tool handling on automatic machines and tapping heads. The tool is specified for blind‑hole application and for a broad range of materials — steel, stainless steel, spheroidal cast iron and non‑ferrous metals — reducing the need for multiple specialised taps. The universal character of the tool supports straightforward process planning: one tool covers several materials, reducing inventory complexity and supporting leaner supply chains.

FAQ

Which materials is this machine tap suitable for?
The TECWERK machine tap DIN 371C M6 x 1 HSS‑Co is designed for steel, stainless steel, spheroidal cast iron and a range of non‑ferrous metals, as stated in the product specification.

Can this tap be used for blind holes?
Yes, the tool is specified for blind‑hole threading; the 40° spiral and flank honing improve chip evacuation and reduce the risk of chip packing in blind bores.

What does HSS‑Co mean and why is it beneficial?
HSS‑Co denotes a cobalt‑alloy high‑speed steel; the addition of cobalt increases hot hardness and wear resistance, which helps maintain cutting performance and extend tool life under demanding conditions.

What tolerance and standard does the tap meet?
The tap produces threads to the ISO2 (6H) tolerance field in accordance with DIN 13 sheet 1, providing consistent fit and interchangeability for metric ISO threads.

What is the shank diameter and how does it affect holder selection?
The shank diameter is 6 mm, enabling direct mounting in standard collets and tool holders designed for that shank size without special adapters.
