Ruko machine tap DIN 376B M16×2 HSS 6H — straight-flute, Form B

Ruko machine tap DIN 376B M16×2 HSS 6H designed for machine tapping of metric ISO threads in production environments, optimised for through-threads in steels, grey cast iron and non‑ferrous metals

• High-speed steel (HSS) construction
• Straight-flute Form B geometry
• Metric ISO M16×2 thread, tolerance 6H
• 12 mm shank, right-hand cutting

Consistent thread accuracy for repetitive production

The combination of HSS material and a Form B straight-flute geometry delivers durable cutting performance and consistent thread profiles. Conformance to DIN 13, sheet 1 and the ISO2 (6H) tolerance field ensures interchangeability and predictable fit with standard threaded components. In practice, this means fewer rejected parts and less rework during mid- to high-volume tapping operations, supporting reliable cycle times in automated or semi-automated machines.

Optimised design for through-threads and chip evacuation

Equipped with a peeling chamfer (Schälanschnitt) for through-threads and flanks relief-ground, the tool promotes controlled chip formation and evacuation. The straight flute design facilitates chip removal in blind and through-hole applications where guided chip flow is critical. The result is reduced jamming, improved thread quality and a lower risk of tool fracture under continuous operation, especially when paired with appropriate machine lubrication and feed settings.

Clear material suitability and application limits

The tool is specified for unalloyed and low-alloy steels up to 800 N/mm² tensile strength, temper cast iron and various non‑ferrous metals. The straight-flute machine tap is particularly suited to standard production tapping on tapping heads or CNC machines where rapid, repeatable cycles are required. Hardening beyond the stated limits is not covered by the specification; for hardened materials, selection of specialised tooling is advised to maintain process integrity.

Practical integration and workshop benefits

With a 12 mm shank and right-hand cutting orientation, the tap integrates easily into conventional tool holders and collets. The use of standard thread geometry and tolerance class supports downstream assembly without additional inspection overheads. Sourcing through Metav brings the advantage of a consistent quality filter for workshop supplies, simplifying procurement and ensuring a supply chain suited to industrial demands.
