20mm Metric Thread Tap MF20x1.5 HSS-Co Form B Straight Flute 6H Tolerance, 16mm Shank - TECWERK

Take advantage of the combination of wear‑resistant HSS‑Co construction, precise 6H tolerance and a through‑hole cutting chamfer for consistent fine‑thread performance; order the thread cutter via Metav Werkzeuge or consult their specialists for application advice.

TECWERK machine tap DIN 374B MF20×1.5 HSS‑Co, Form B

TECWERK machine tap DIN 374B MF20×1.5 HSS‑Co, Form B is a through‑hole tapping tool engineered for metric ISO fine threads in steels and long‑chipping non‑ferrous metals

• HSS‑Co for higher heat resistance
• Form B straight flutes for reliable chip evacuation
• Metric ISO fine thread MF20×1.5, tolerance 6H
• Shank Ø16 mm for standard toolholders

Robust alloy for long tool life and consistent results

The HSS‑Co composition provides increased red hardness and wear resistance compared with standard high‑speed steel, which is beneficial where sustained cutting temperatures occur. Specified to work in steels up to approx. 1000 N/mm², as well as temper cast iron and long‑chipping non‑ferrous metals, the material choice reduces flank wear and extends service intervals. Combined with the DIN 374B designation and 6H tolerance, this configuration supports repeatable, industry‑compliant thread quality and interchangeability in precision assemblies.

Geometry designed for reliable chip control and thread form

The Form B geometry with straight flutes and ground flanks helps maintain thread profile accuracy while easing chip flow in through‑hole applications. The integrated through‑hole chamfer (Schälanschnitt) is tailored for cutting exit threads cleanly, which reduces burr formation and post‑process finishing. With the MF20×1.5 thread profile, the tool delivers fine‑pitch accuracy for components that demand close fitment, and the shank Ø16 mm ensures compatibility with common collets and toolholder systems in production environments.

Practical benefits for workshop and production environments

Incorporating this machine tap into a production line or workshop reduces rework by delivering consistent thread tolerances and cleaner exits on through holes. The tool’s specifications favour batch and single‑part manufacture where fine threads and interchangeability are required. Clear technical definition—material, tolerance and geometry—simplifies process planning and contributes to predictable cycle times. For complex applications or confirmation of fitment in a specific machine, Metav Werkzeuge offers technical guidance to ensure the threading tool integrates seamlessly with existing tooling systems.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap DIN 374B MF20×1.5 HSS‑Co 6H (SKU 2000867476NW) is specified for steels up to approx. 1000 N/mm², temper cast iron and long‑chipping non‑ferrous metals.

Why is the 6H tolerance important?
A 6H tolerance ensures a consistent internal thread fit according to metric ISO standards, supporting interchangeable assemblies and accurate mating with standard fasteners.

Is the tool suitable for through‑hole threading?
Yes; the integrated through‑hole chamfer is designed to produce clean exit threads and reduce burrs on through holes.

What does Form B and straight flutes mean for production?
Form B with straight flutes improves chip evacuation in through‑hole operations and helps to preserve the thread profile during continuous or series production.

Which holders fit the tap?
The shank Ø16 mm allows use with common collets and standard toolholders; adaptors can be used where different interfaces are required.
