Machine Tap DIN 374B MF14×1 HSS‑Co 6H – TECWERK

Machine Tap DIN 374B MF14×1 is a straight‑fluted, high‑precision tap for cutting metric ISO fine threads in machine applications across steels and long‑chip non‑ferrous metals

• HSS‑Co for improved wear resistance
• Straight‑fluted Form B for controlled chip flow
• Metric ISO fine thread MF14×1 with tolerance 6H
• Shaft Ø 11 mm for secure machine mounting

Precision thread form for consistent assemblies

The Machine Tap DIN 374B MF14×1 is engineered to produce consistent metric ISO fine threads with the 6H tolerance grade specified in DIN 13, ensuring reliable mating with standard components. The close tolerance and standard conformity reduce rework and eliminate guesswork in assembly processes, which supports predictable part interchangeability. Designed for machine tapping, the tool sustains thread quality over repeated cycles, translating into fewer rejects and steadier production yields when machining components that require precise fine threads.

Geometry that supports efficient machining cycles

Form B geometry and straight‑fluted design provide reliable chip control in through‑hole tapping. The tool’s shear‑cut chamfer promotes gradual thread entry and is optimised for through threads, reducing the risk of chip packing and thread damage. Flank relief grinding improves thread profile accuracy and eases cutting forces, while the shaft Ø 11 mm offers stable clamping in machine holders. Together, these features deliver smoother tapping runs, reduced cycle interruptions and predictable tool behaviour when integrated into CNC or automated tapping setups.

Material choice and application range for durable performance

Manufactured from HSS‑Co, the tap offers elevated red hardness and wear resistance compared with standard high‑speed steels, making it suitable for steels up to approximately 1000 N/mm² tensile strength, malleable cast iron and long‑chip non‑ferrous metals. This material and the relief‑ground flanks extend tool life under intermittent or continuous production, lowering downtime for tool changes. The clear specification of material suitability allows planners to select the correct cutting parameters and cooling strategy, improving process security and overall cost‑effectiveness per produced part.

Practical benefits for workshop and production planning

Adopting a dedicated machine tap with defined standards simplifies tool inventory and process documentation. The DIN conformity and explicit tolerance class make quality assurance straightforward: thread gauges and inspection routines can be applied uniformly. The robust shank diameter and machine‑oriented design reduce set‑up variation, supporting higher first‑pass yields. For facilities aiming to streamline their tapping operations, the combination of HSS‑Co toughness and Form B geometry offers a balanced solution between cutting performance and lifecycle costs.

FAQ

What materials can this tap machine through reliably?
The TECWERK machine tap is suitable for steels up to approx. 1000 N/mm² tensile strength, malleable cast iron and long‑chip non‑ferrous metals as stated in the technical data.

Is the thread form compatible with standard gauges?
Yes. The tap cuts a metric ISO fine thread to DIN 13 specifications with tolerance 6H, ensuring compatibility with standard thread gauges and mating parts.

What advantages does HSS‑Co offer for production runs?
HSS‑Co provides higher red hardness and improved wear resistance, which extends tool life during continuous or high‑temperature cutting compared with conventional HSS tools.

How does the Form B, straight‑fluted design affect chip control?
The straight‑fluted Form B geometry promotes consistent chip evacuation in through‑hole tapping and the shear‑cut chamfer reduces chip build‑up at the thread entry.

Which shank size is required for machine holders?
The tap has a shaft Ø 11 mm, designed for secure clamping in compatible machine tool holders and tapping attachments.
