Take advantage of the combination of HSS‑Co heat resistance, nitrided and vapour‑treated wear protection, and precise ISO2 (6H) tolerance for reliable thread production; order directly via Metav Werkzeuge or consult our specialists for machining recommendations.

Machine tap DIN 376B VA M12×1.75 – HSS‑Co, nitrided & vapour‑treated (TECWERK)

The machine tap DIN 376B VA M12×1.75 is a robust cutting tool for producing metric threads in high‑strength, corrosion‑resistant steels and similar alloys.

• HSS‑Co construction for high‑temperature strength
• Nitrided and vapour‑treated surface for wear resistance
• Straight flute with relieved flanks for smooth chips
• Tolerance ISO2 (6H) for precise metric threads

Optimised performance in high‑duty steels

This machine tap is manufactured from HSS‑Co, a cobalt‑alloy high‑speed steel that retains hardness at elevated cutting temperatures. The material choice enables higher cutting data and extended tool life when machining stainless, acid‑ and heat‑resistant steels with tensile strengths >850 N/mm². For operations where frequent tool changes would disrupt production, the enhanced hot‑hardness of the tool reduces downtime and contributes to a more consistent process capability.

Accurate threads that reduce rework

Precision is built into the geometry: the cutter complies with DIN 13 (Sheet 1) and the threads are finished to ISO2 (6H) tolerance, ensuring repeatable assembly fits without additional hand‑fitting. The controlled flank relief and ground flank surfaces lower insertion torque and improve thread runout, which helps decrease scrap rates and rework. A 9 mm shank diameter provides compatibility with standard machine holders for secure clamping and concentricity.

Surface treatment and flute design for reliable chip control

The combined nitrided and vapour‑treated surface improves wear resistance and reduces adhesive wear on reactive alloys; this is particularly valuable when cutting stainless and heat‑resistant steels prone to galling. The straight flute geometry, together with relieved flanks, promotes dependable chip formation and evacuation in through‑hole applications, while the dedicated cutting chamfer for through threads ensures reliable thread starts and reduces the risk of chip jamming. These design choices translate directly into fewer broken taps and smoother cycle times.

Practical benefits on the shop floor

Choosing a tool with these attributes delivers tangible operational benefits: longer tool life, predictable cycle times and fewer interruptions. The mechanical characteristics and surface treatment are particularly suited to series production and components that demand consistent thread quality. For workshops upgrading from general‑purpose taps, this specialised cutter can raise throughput while simplifying process planning and tool inventory.

FAQ

What materials can be machined with this tap?
This TECWERK machine tap (SKU 2000867352NW) is intended for stainless, acid‑ and heat‑resistant steels and other alloys with tensile strength above 850 N/mm².

What does HSS‑Co mean and why is it important?
HSS‑Co denotes high‑speed steel with cobalt, a tool steel variant that maintains hardness at elevated temperatures, improving wear resistance and cutting performance during high‑speed or arduous threading operations.

How do the nitrided and vapour‑treated surfaces affect performance?
The nitrided and vapour‑treated finish increases surface hardness and reduces adhesion between chip and tool, which improves tool life and lowers the tendency to gall when threading reactive alloys.

Which tolerance and standards does the tap meet?
Threads are produced to ISO2 (6H) tolerance and the geometry follows DIN 13 Sheet 1, delivering reliable dimensional conformity for metric fastenings.

What machine holder fits the tap?
The tap has a 9 mm shank diameter, compatible with standard machine holders and tapping heads designed for straight‑shank tools.
