Take advantage of precise metric fine-thread production and long tool life with the strength of HSS‑Co and a vapour coating; the result is consistent, ISO‑class thread accuracy and reduced rework. Order the machine tap directly via Metav Werkzeuge or consult the Metav team for application advice.

Machine tap DIN 374B — MF12 × 1.25 HSS‑Co, Universal (TECWERK)

The Machine tap DIN 374B is a universal high-speed steel cobalt tool for cutting MF12×1.25 metric fine threads in a wide range of metals, designed for use in production machines and tapping heads

• HSS‑Co for high wear resistance
• Vapour‑coated for improved lifespan
• Straight flute for reliable chip evacuation
• ISO2 (6H) tolerance for accurate threads

Consistent fine-thread accuracy for production use

The Machine tap DIN 374B combines HSS‑Co construction with ISO‑class tolerance to deliver repeatable results in production runs. The designation MF12×1.25 indicates a metric fine thread; paired with the 6H tolerance field this ensures a snug, standard-compliant fit in mating parts. Using a tool with such specification reduces the likelihood of rejects and post-process rework, which supports efficient throughput on the shop floor. The robust material composition also contributes to dimensional stability under load.

Cutting geometry that supports clean chips and reliable form

A straight-flute design with relieved flanks and a chamfered lead for through threads optimises chip flow and reduces the risk of clogging in blind or through holes. The vapour‑coated surface treatment and green ring identification mark indicate enhanced surface hardness and quick recognition in tool racks. These geometry choices make the tool suitable for continuous machining where predictable chip behaviour and consistent thread form are essential, particularly when working with a range of alloys.

Wide application range and secure clamping

The tool is specified for machining steel, stainless steels, spheroidal cast iron and non‑ferrous metals, offering versatility across maintenance, prototyping and serial production tasks. The Form B, universal type design is compatible with common machine tap holders and tapping spindles; the 9 mm shank provides a compact mounting diameter for use in multi-spindle or automated cells while maintaining sufficient rigidity for precise thread generation. This combination supports flexible integration into existing machining setups.

Practical handling and shop-floor recommendations

To prolong service life and maintain thread quality, apply appropriate cutting fluid for the work material and ensure correct spindle alignment and feed control during tapping cycles. The vapour coating enhances surface durability but does not substitute for correct machining parameters; controlled feed and regular inspection of thread form will secure the expected service life. Supplied as a single unit, the tool is ready for immediate installation in production or maintenance environments.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is specified for steel, stainless steels, spheroidal cast iron and non‑ferrous metals, making it suitable for diverse machining tasks.

What thread and tolerance does the tool produce?
This tool cuts an MF12 × 1.25 metric fine thread to the ISO2 (6H) tolerance, delivering standardised fits for mating components.

Is the tap intended for through holes or blind holes?
The design includes a chamfered lead for reliable performance in through threads, while the straight flute and relieved flanks also permit use in many blind-hole applications with appropriate chip control.

What is the shank diameter and how does it affect mounting?
The shank diameter is 9 mm, which facilitates secure clamping in standard small-diameter tap holders and is suitable for multi-spindle and machine tap systems.
