M20x2.5mm Machine Tap DIN 376B H HSS-Co 6H Straight Flute With Margin and Shallow Lead, 16mm Shank - TECWERK

Take advantage of the combination of HSS‑Co cutting material, a shearing chamfer for through threads, and a 6H ISO tolerance to ensure reliable, repeatable metric threading in high‑strength steels; order the tap directly via Metav Werkzeuge or consult their specialists for application advice.

Machine tap DIN 376B H M20x2.5 HSS‑Co, 6H – TECWERK

The Machine tap DIN 376B H M20x2.5 is a heavy‑duty metric tap designed for through‑threading of hard‑to‑machine steels in production and workshop environments.

• HSS‑Co for enhanced wear resistance
• Straight flute with honed flanks
• Metric ISO thread M20x2.5, tolerance 6H
• Shaft Ø 16 mm for secure machine clamping

Consistent thread quality for demanding materials

The DIN‑specification construction and HSS‑Co substrate deliver consistent results when machining high‑strength alloys. Built to cope with materials above 1000 N/mm², this machine tap maintains cutting edge integrity and dimensional stability across runs. The 6H tolerance corresponds to ISO2 precision and supports reliable assembly with mating threads; this lowers rework rates and shortens inspection cycles. For manufacturers prioritising reproducibility, the tool’s geometry reduces chatter and produces clean flank forms on each thread.

Efficient cutting geometry that reduces cycle time

Featuring a straight flute and flanks honed to fine tolerance, the design promotes efficient chip evacuation in through‑hole applications and reduces the risk of tool breakage. The integrated shearing chamfer for through threads initiates the cut smoothly and limits the formation of long chip segments, which in turn supports faster feed rates and safer automatic operation. The robust shaft Ø 16 mm ensures secure clamping in power tapping holders, contributing to stable runout and fewer rejected parts during high‑volume production.

Compatibility and practical workshop integration

Conforming to DIN 13 Sheet 1 and producing a standard M20 x 2.5 metric thread, the tap matches common industrial thread specifications and workpiece designs. The form and Type H designation indicate suitability for machine tapping; the red ring marking (Rotring) assists rapid visual identification in tool cabinets. For workshop planners, the combination of standard dimensions and a familiar shank diameter simplifies toolholder selection and changeover procedures, helping to reduce downtime between batches.

Long‑term value through predictable maintenance

The choice of a cobalt‑alloy high‑speed steel enhances resistance to thermal softening and abrasive wear, extending tool life under elevated cutting temperatures. The honed flanks and precise geometry allow straightforward regrinding cycles where applicable, supporting planned maintenance strategies rather than unscheduled replacements. Selecting this tap supports predictable tooling costs and aligns with quality‑control measures that value repeatability and reduced scrap rates across production runs.

FAQ

What materials can this tap machine effectively thread?
The TECWERK machine tap is specified for hard‑to‑machine steels and is suitable for materials with strength above 1000 N/mm², making it appropriate for many alloyed and quenched steels.

Which tolerance and thread quality does the tool deliver?
The tap produces a metric ISO thread M20 x 2.5 with ISO2 (6H) tolerance, providing the dimensional quality expected for standard industrial assemblies and interchangeable components.

Is the tap suitable for automatic machine tapping?
Yes; with Type H geometry and a shaft Ø 16 mm, the tap is designed for machine tapping holders and stable clamping in powered tapping operations.

How does the shearing chamfer affect performance?
The shearing chamfer for through threads reduces chip formation and initiates cutting smoothly, improving chip control and lowering the risk of breakage in through‑hole applications.

Can the tool be resharpened to extend service life?
The honed flanks and conventional geometry permit regrinding where appropriate; following manufacturer guidelines and using qualified regrinding services will help preserve thread quality and tool life.
