M12x1.75mm Machine Tap HSS-Co Nitride Vaporised ISO Metric 6H For Blind Holes - TECWERK

Take advantage of the HSS‑Co construction, nitrided and vapour‑deposited surface and the 40° right‑hand spiral to produce precise ISO metric threads in demanding, corrosion‑resistant steels; order the tap directly via Metav Werkzeuge or consult our specialists for application support.

TECWERK Machine Tap DIN 376C M12 x 1.75 — HSS‑Co, nitrided & vapour‑treated

A TECWERK machine tap designed for ISO metric M12 x 1.75 threads, optimised for blind‑hole tapping in high‑strength, corrosion‑resistant steels.

• Cobalt HSS for high strength cutting
• Nitrided and vapour‑treated surface
• 40° right‑hand spiral for chip control
• For M12 x 1.75 ISO metric threads (6H)

Reliable thread accuracy in high‑strength materials

This machine tap delivers consistent ISO metric threads in materials that demand elevated tensile strength. The tool is matched to M12 x 1.75 thread geometry and complies with DIN 13 Blatt 1, producing the ISO2 (6H) tolerance field required for many industrial assemblies. Designed specifically for blind‑hole threads, the geometry reduces the risk of chip packing at depth; this ensures repeatable thread form and reliable assembly fit in components made from rust‑, acid‑ and heat‑resistant steels with strength above 850 N/mm². Where dimensional certainty is required, these characteristics support process stability and reduce rework.

Engineered for performance and extended tool life

Manufactured from HSS‑Co (cobalt high‑speed steel) and finished with a nitrided and vapour‑deposited surface, the tool combines toughness with a wear‑resistant top layer that improves life under thermal and abrasive load. The flank‑ground cutting edges sharpen the engagement and reduce cutting forces, while the 40° right‑hand spiral optimises chip formation and evacuation in blind holes, lowering the risk of jamming. These features together mean fewer tool changes, less downtime and a more economical tapping cycle in production environments where machining hours count.

Simple integration into machine tool workflows

The tap is built to the DIN 376C machine‑tap form with a shank Ø 9 mm, allowing secure mounting in standard holders and automatic tapping spindles. Its colour‑coded blue ring aids quick visual identification on the tool trolley. For workshops and production lines seeking reduced supplier complexity, the tool’s specification supports straightforward replacement of worn taps without process redesign. If further machining parameters are needed for a specific alloy or cycle, Metav Werkzeuge provides technical guidance and additional data to align the tool with the chosen machining strategy.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap (M12 x 1.75, SKU 2000867412NW) is specified for rust‑, acid‑ and heat‑resistant steels with tensile strength above 850 N/mm² and is suitable where high corrosion resistance is required.

Is the tap designed for blind or through holes?
This tool is configured for blind‑hole threads; the 40° right‑hand spiral and flank‑ground geometry assist chip evacuation and reduce the risk of chip packing in blind holes.

What does the tolerance ISO2 (6H) mean for assembly?
ISO2 (6H) indicates a standardised internal thread tolerance that provides a predictable clearance for mating bolts or studs; the TECWERK tap produces this tolerance for reliable fits in industrial assemblies.

How does the nitrided and vapour‑deposited finish help in production?
The nitrided and vapour‑deposited surface increases wear resistance and thermal stability, extending tool life and maintaining cutting performance under higher temperatures and abrasive conditions.

Which shank sizes and holders are compatible with this tap?
The tap has a shank Ø 9 mm and is made to DIN 376C dimensions, permitting secure clamping in standard holders and automatic tapping spindles suitable for machine tapping operations.
