Take advantage of a high-performance HSS‑Co cutting geometry and a 40° right‑hand spiral to ensure efficient chip evacuation and reliable thread form in blind holes; purchase directly through Metav Werkzeuge for fast supply or consult our specialists for application advice.

TECWERK Machine Tap MF8×1 mm (DIN 374C) – HSS‑Co, 6H, right‑hand spiral

The TECWERK Machine Tap MF8×1 is a spiral‑fluted machine tap designed for machining metric fine internal threads in blind holes across a range of steels and long‑chipping non‑ferrous materials.

• HSS‑Co high‑speed steel for enhanced wear resistance
• Right‑hand 40° spiral for secure chip evacuation
• DIN 374C specification, metric fine thread MF 8 × 1
• Tolerance 6H with flank‑honed cutting edges

Reliable fine‑threading in blind holes for consistent assemblies

The spiral geometry and Form C configuration deliver controlled chip transport away from the cutting edge, which is essential when working with blind holes. The 40° right‑hand spiral promotes reliable evacuation of chips into the shank, reducing the risk of chip re‑cutting and thread damage. This design translates into fewer interrupted cycles and more consistent thread profiles, supporting a steady production flow in machining centres and automatic tapping units.

Long tool life and broad material compatibility to lower operating cost

Constructed from HSS‑Co (cobalt‑alloyed high‑speed steel), the tool offers improved hardness retention at elevated temperatures compared with standard HSS, which results in longer tool life during continuous tapping. The geometry and material combination are rated for use in steels up to approx. 1000 N/mm² tensile strength, temper cast iron and long‑chipping non‑ferrous metals, allowing one item to cover multiple applications and reduce tool changes. The result is a measurable decrease in downtime and consumable turnover for workshops and production lines.

Precise thread quality that reduces rework and inspection effort

A tolerance field 6H in accordance with ISO metric standards ensures a close functional fit with mating parts, while the flank‑honed cutting edges improve surface finish and reduce burr formation. These features minimise post‑machining work and lower rejection rates during quality control. With a compact shank diameter of 6 mm, the tap is compatible with common tool holders and tapping chucks, enabling quick integration into existing tool assemblies without special adaptors.

FAQ

What hole preparation is recommended before using this tap?
A clean, accurately sized pilot hole according to the MF 8 × 1 mm recommendation and correct tapping lubricant will help the TECWERK machine tap produce the intended thread profile and extend tool life.

Can this tap be used in a production tapping head?
Yes, the MF 8 × 1 mm tap in HSS‑Co and with a 6 mm shank is compatible with standard tapping chucks and automated tapping units commonly used in production environments.

Which materials are suitable for this type of tap?
The tap is suitable for a range of materials including steels up to approx. 1000 N/mm² tensile strength, temper cast iron and long‑chipping non‑ferrous metals, benefiting from the heat resistance of the cobalt‑alloyed steel.

How does the flank‑honed edge affect the thread quality?
Flank honing reduces burr formation and improves surface finish on the thread flank, resulting in better mating behaviour and fewer rework operations when using the TECWERK MF 8 × 1 machine tap.
