M30x3.5mm Machine Tap DIN 376B VA HSS-Co Nitride Vaporised ISO2 (6H), 22mm Shank - TECWERK

Take advantage of a robust combination of HSS‑Co cutting material and nitride/vapour surface treatment for longer tool life and consistent thread quality; the M30 x 3.5 mm metric tap with ISO2 (6H) tolerance ensures precise, repeatable assembly. Order the tool through Metav Werkzeuge or consult their specialists for application-specific recommendations.

TECWERK machine tap M30 x 3.5 mm (HSS‑Co, DIN 376B)

A machine tap M30 x 3.5 mm designed for producing metric ISO through‑threads to DIN 376B, suitable for demanding applications in stainless, acid‑ and heat‑resistant steels.

• HSS‑Co material for increased wear resistance
• Nitride and vapour surface treatment
• Straight flutes with relieved flanks
• Designed for stainless and heat‑resistant steel

Accurate threads for industrial production and assembly

This threading tool is engineered to meet the requirements of modern production: the DIN 376B specification and ISO2 (6H) tolerance give assured interchangeability and dimensional reliability for bolted assemblies. The metric thread form M30 x 3.5 mm is produced with a machined heel and a dedicated cutting geometry, resulting in consistent thread profiles and reduced rework. For procurement and planning, the clear compliance with standards translates into predictable assembly performance and fewer rejects in batch manufacturing.

Cutting geometry and surface treatment optimised for tough alloys

Constructed from HSS‑Co, the tap provides improved hot hardness and wear resistance compared with standard high‑speed steels; this supports sustained performance when machining work‑hardening or temperature‑sensitive alloys. The nitride and vapour coating lowers friction and helps prevent built‑up edge during threading, while the straight flutes and relieved flanks ease chip evacuation in through‑threading operations. These features together reduce cycle interruptions and extend tool life when tackling steels with a tensile strength above 850 N/mm².

Machine compatibility, handling and operational benefits

Delivered in Form B, Type VA with a shaft Ø 22 mm for secure clamping, the tap carries a Schälanschnitt (peeling cut) specifically for through‑threads, enabling fast penetration and clean thread start. The robust shank diameter supports high‑precision spindles and automatic tool changers commonly found in production machinery. Using this machining option reduces downtime, improves first‑pass yield and contributes to leaner processes in workshops and small industrial plants.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap M30 x 3.5 mm is intended for stainless, acid‑resistant and heat‑resistant steels and is specified for workpieces with tensile strength above 850 N/mm².

Which standard and tolerance does the tap comply with?
Compliance with DIN 376B and an ISO2 (6H) tolerance field ensures the produced threads meet recognised metric ISO thread standards for interchangeability.

Is the tool coated and how does that affect performance?
Yes — the tool features a nitride and vapour surface treatment; this reduces friction, limits built‑up edge and extends the service life of the HSS‑Co cutting material.

Can this tap be used for blind holes as well as through‑holes?
The tap is equipped with a Schälanschnitt intended for through‑threading; for blind holes, consider a tool specified for interrupted exit conditions or consult Metav Werkzeuge for alternatives.

What clamping diameter is required for the tap?
The tool has a shank diameter of 22 mm, providing a secure interface for compatible machine holders and collets.
