Maschinengewindebohrer DIN 374B MF27×2 mm — machine tap, HSS‑Co, 6H tolerance (TECWERK)

A TECWERK machine tap designed for producing metric ISO fine threads MF27×2 in through‑hole applications, optimised for high‑strength steels and long‑chipping non‑ferrous materials.

• HSS‑Co material for extended tool life
• Straight‑fluted Form B for reliable chip flow
• Tolerance 6H for accurate thread fit
• Suitable for steels up to 1000 N/mm²

Consistent fine threads with industrial durability

Manufactured from HSS‑Co, this machine tap delivers a balance of hardness and toughness that prolongs service life under demanding production conditions. The Form B straight flutes and the specially ground flanks reduce cutting forces and support predictable wear patterns, which translates into fewer rejects and more predictable cycle times. For production environments where repeatable thread quality is essential, this tool combines material technology and geometry to maintain thread integrity across extended runs.

Broad material capability explained for workshop planners

The tool is rated for machining in steels up to approximately 1000 N/mm², along with temper‑cast iron and long‑chipping non‑ferrous metals. The quoted tensile strength gives a practical limit for common structural and engineering steels; selecting a tap suited to that range avoids premature wear and maintains thread accuracy. Using a tool matched to the workpiece material reduces thread‑repair needs and supports efficient downstream assembly, especially where fine metric threads are specified by DIN 13.

Precise fit and reduced rework through tolerance control

The combination of DIN 13 standardisation and 6H tolerance ensures a snug, standardised internal thread fit for metric fine threads. A 6H tolerance class typically provides a reliable fit with standard bolts, reducing the likelihood of play or interference that can cause assembly problems. The inclusion of a cutting chamfer for through threads simplifies the initial engagement and helps avoid burr formation at the thread start, which lowers the need for secondary finishing.

Operational advantages and workshop integration

A 20 mm shank offers stable clamping in toolholders and adapters commonly found in machining centres and tapping heads. The straight‑flute configuration aids chip evacuation in through‑hole tapping and helps maintain thread form when cutting long‑chipping materials. Together, these features improve cycle reliability and reduce stoppages for clearing chips, supporting a smoother production flow and predictable maintenance intervals.

FAQ

Is this tap suitable for through‑hole tapping in steel?
Yes. The TECWERK machine tap is specified for through‑hole threads and is suitable for steels up to approximately 1000 N/mm², with a cutting chamfer optimised for clear thread starts.

What does the 6H tolerance mean for assembly?
A 6H tolerance on the internal thread gives a standard, reliable fit with commonly used metric bolts; it reduces play while allowing standard external thread tolerances to assemble without interference.

Can this tap be used for non‑ferrous metals such as aluminium or brass?
Yes. The tool’s geometry and HSS‑Co material make it suitable for long‑chipping non‑ferrous metals, providing controlled chip formation and evacuation.

What is the shank size and how does it affect tooling?
The shank diameter is 20 mm, which is compatible with standard holders and tapping heads used in industrial machining centres, ensuring stable clamping and improved concentricity.

Which standards are referenced for the thread form and tolerance?
The tap adheres to DIN 13 for metric fine threads and is manufactured to DIN 374B specifications with a 6H tolerance class; the SKU is 2000867277NW for ordering and specification checks.
