Machine tap DIN 376B M20×2.5 HSS 6H by RUKO — Form B straight flute, ISO2 (6H) tolerance

A Machine tap DIN 376B M20×2.5 HSS 6H engineered for producing metric through threads in unalloyed and low‑alloy steels, cast iron and non‑ferrous materials

• HSS construction for lasting edge life
• Form B straight flutes for predictable chips
• ISO metric M20×2.5 with tolerance 6H
• Shank Ø 16 mm, right‑hand cutting

Consistent, ISO‑compliant threads for production use

The combination of HSS tool steel and a defined metric profile ensures repeatable thread quality in series production. The M20×2.5 profile manufactured to tolerance ISO2 (6H) gives a reliable fit that reduces rework and inspection effort. The tool’s conformity with DIN 13 Blatt 1 provides a verifiable standard reference, supporting process documentation and quality control. This makes the tap suitable where dimensional consistency and interchangeability are imperative.

Geometry designed to control chips and reduce interruptions

The Form B geometry with straight flute design and relief on the flank creates predictable chip formation ideal for through‑hole tapping. The integrated peel cut for through threads assists chip evacuation and lowers the risk of chip jamming during high‑volume cycles, which in turn shortens machine downtime. These characteristics support faster cycle times and steadier production flow without compromising thread integrity.

Broad material compatibility and workshop durability

Specified for use in unalloyed and low‑alloy steels up to 800 N/mm², plus temper‑cast iron and non‑ferrous metals, the tool covers the most common workshop applications. HSS provides a favourable balance of toughness and wear resistance for intermittent cutting loads encountered in standard machining shops. The result is dependable tool life and steady performance where diverse materials are processed on the same machine.

Practical integration for machine shops and CNC cells

A shank Ø 16 mm ensures stable clamping in standard toolholders while the right‑hand cutting orientation matches conventional spindle setups. The product’s straightforward geometry simplifies fixture planning and reduces the need for special tooling, aiding rapid changeovers. Metav’s supply chain and quality filter in Emmerich back this item with assured availability and consistent manufacturing standards, supporting uninterrupted workshop operations.

FAQ

Which materials can be machined with this tap?
The machine tap is intended for unalloyed and low‑alloy steels (up to 800 N/mm²), temper cast iron and common non‑ferrous metals; the combination of HSS and the specified geometry supports these materials.

Is this tap suitable for through threads or blind holes?
The tool features a peel cut for through threads, making it optimised for through‑hole tapping; blind‑hole applications typically require a different chamfer length or specialised tap geometry.

What thread standard and tolerance does the tap meet?
Threads are produced to the ISO metric profile M20×2.5 and tolerance ISO2 (6H) in accordance with DIN 13 Blatt 1, ensuring standardised fit and interchangeability.

What are the shank size and cutting direction?
The tap has a shank Ø 16 mm and is manufactured for right‑hand cutting, compatible with standard machine spindles and holders.

How does the Form B straight flute influence machining?
The Form B straight flute promotes predictable chip formation and reliable evacuation in through‑hole operations, reducing the risk of jamming and supporting uninterrupted production cycles.
