M20x2.5mm Machine Tap DIN 376C HSS-Co TiN Coated 6H For Blind Holes, 16mm Shank - TECWERK

Take advantage of the durability of a cobalt-alloy tool and the wear protection of a TiN coating for consistent, high-quality internal threads; order the tap directly via Metav Werkzeuge or request technical advice from their specialists.

Machine Tap DIN 376C – M20 x 2.5 mm, HSS‑Co, TiN (TECWERK)

The Machine Tap DIN 376C M20 x 2.5 mm is a Form C machine tap engineered for producing metric internal threads in blind holes, optimised for steels up to 1000 N/mm².

• HSS‑Co with TiN coating for wear resistance
• 40° right‑hand spiral for blind‑hole chips
• ISO metric thread M20×2.5 to DIN 13, tolerance 6H
• 16 mm shank, Form C — machine tap design

Consistent thread quality with reduced downtime

Made from HSS‑Co (cobalt‑alloy high‑speed steel) and finished with a TiN surface layer, this tap delivers a balance of toughness and wear resistance that supports predictable tool life. The combination of material and coating reduces flank wear and maintains cutting geometry across longer production runs, which in turn supports stable cycle times and fewer tool changes. For production environments where thread accuracy matters, the M20×2.5 metric specification and 6H tolerance conform to recognised standards and help ensure interchangeability of fastened components.

Designed for secure chip control in blind holes

A 40° spiral with right‑hand helix directs chips away from the cutting face into the flutes, a decisive advantage when machining blind holes. The flanks are relief‑ground to lower friction and ease entry, reducing the risk of jamming and improving the surface finish of the internal thread. As a Form C machine tap with a 16 mm shank, it integrates readily with common holders and collet systems used in automated tapping units, enabling reliable chip evacuation and repeatable thread profiles in series production.

Clear material application and practical benefits

This tool is specified for use in steels up to 1000 N/mm² tensile strength, making it suitable for a broad range of mild and alloy steels encountered in workshop and light industrial contexts. The tap adheres to DIN 13 metric thread standards and produces ISO metric threads designed for general assembly. The material and geometry choices translate into fewer rejects and less rework: a pragmatic improvement to throughput and quality assurance that benefits both jobbing shops and dedicated production cells.

Integration into the workshop and purchasing confidence

Selecting this machine tap supports a straightforward tool management strategy: standard metric threads, a common shank diameter and industry‑standard form simplify stock keeping and tooling changeover. Metav Werkzeuge’s position as a precision partner adds further reassurance — thousands of workshops rely on consistent product quality and a consolidated supplier range to streamline procurement and operations. Technical documentation and matching holders or accessories can be sourced to ensure the tap’s performance is realised on the intended machines.

FAQ

What materials is this tap suitable for?
The TECWERK machine tap is specified for machining steels with tensile strengths up to 1000 N/mm² and is intended for standard workshop and production steels.

Is the tap suitable for blind‑hole threading?
Yes. The tool’s 40° right‑hand spiral and Form C geometry are designed specifically to improve chip evacuation in blind holes.

What does HSS‑Co mean and why is it used here?
HSS‑Co indicates cobalt‑alloy high‑speed steel; this material provides enhanced hot hardness and toughness compared with standard high‑speed steel, supporting longer tool life under production loads.

Which thread accuracy and standard does the tap meet?
The tap produces ISO metric threads according to DIN 13 Sheet 1 with tolerance field 6H (ISO2), ensuring standardised fit and interchangeability.

What is the article number for ordering or reference?
The article number for this TECWERK machine tap is 2000867321NW.
