20mm Machine Tap DIN 374B MF20x2mm HSS-Co 6H Straight Flute Counter-Sink Shank 16mm - TECWERK

Take advantage of the combination of HSS‑Co for high thermal resistance, the Form B straight‑flute geometry for consistent chip formation, and the precise 6H tolerance for reliable fine threads; order the Maschinengewindebohrer DIN 374B MF20x2mm HSS‑Co 6H TECWERK directly via Metav Werkzeuge or ask the consultants for tailored procurement advice.

Maschinengewindebohrer DIN 374B MF20x2mm HSS‑Co 6H – Machine tap with HSS‑Co and straight flutes by TECWERK

Maschinengewindebohrer DIN 374B MF20x2mm HSS‑Co 6H is a machine tap designed for creating metric ISO fine threads MF 20 × 2 mm in a wide range of engineering materials

• HSS‑Co cobalt high‑speed steel construction
• Form B straight flute geometry
• Metric ISO fine thread MF 20×2 mm
• Shank Ø 16 mm for stable machine clamping

High‑performance threads for demanding materials

The tap is made from HSS‑Co, a cobalt‑alloy high‑speed steel that boosts heat resistance and maintains cutting hardness under higher temperatures. This makes the tool particularly suited for machining steels up to approx. 1000 N/mm², temper cast iron and long‑chipping non‑ferrous metals. The choice of material translates into a longer useful life and fewer tool changes on the production line, supporting a steady output and reduced downtime.

Consistent thread quality and machine compatibility

Built to DIN 374B with Form B geometry and a 6H tolerance class, the tool ensures repeatable, high‑quality fine threads that meet ISO requirements. The straight flute design and flank relief ground cutting edges produce accurate thread profiles while simplifying chip evacuation in many through‑hole operations. The shank Ø 16 mm provides secure clamping in common machine tool holders, reducing runout and improving thread concentricity for serial production.

Efficient chip control and lower process forces

Equipped with a dedicated cutting‑edge design for through threads, the tool features a specialised cutting entry that reduces torque and prevents jamming when creating full‑length threads through workpieces. This through‑thread optimisation and the straight flute layout help to manage chips effectively in long‑chipping materials, which in turn reduces rework and contributes to a cleaner machining environment. The result is more efficient cycles and measurable savings in operator time.

FAQ

What thread standard and tolerance does this tap produce?
The Maschinengewindebohrer is made to DIN 374B and cuts a metric ISO fine thread MF 20 × 2 mm with a 6H tolerance class, ensuring compatibility with standard fine‑thread components.

Which materials can be machined with this tap?
This TECWERK tap is suitable for steels up to approx. 1000 N/mm², temper cast iron and long‑chipping non‑ferrous metals, thanks to its HSS‑Co construction and dedicated cutting geometry.

What are the clamping requirements for stable operation?
Secure clamping with a holder matching the 16 mm shank diameter is recommended to minimise runout; this ensures the tap maintains the intended thread form and surface finish throughout a production run.

How does the cutting geometry affect chip formation?
The straight flute and the specially designed cutting entry for through threads reduce torque and promote orderly chip evacuation, lowering the risk of breakage and extending tool life.

Is this tap suitable for automatic machine tapping?
Yes. The machine‑grade shank and the Form B straight‑flute design make the tool appropriate for automated tapping cycles in standard machine tool holders.
