Machine thread tap DIN 371B M4 x 0.7 HSS-Co TiN – TECWERK

A Machine thread tap DIN 371B M4 x 0.7 designed for cutting metric ISO threads in through-hole applications, suitable for steels up to 1000 N/mm².

• HSS-Co construction for enhanced toughness
• TiN coating increases wear resistance
• Straight flutes with ground flanks for clean chips
• Metric ISO thread to DIN 13, tolerance 6H

Consistent thread quality for industrial production

The combination of a cobalt-alloy high-speed steel (HSS-Co) body and a TiN-coated surface delivers improved resistance to flank wear and consistent cutting behaviour over extended runs. Conformity with DIN 13 and the ISO2 (6H) tolerance field ensures that threaded assemblies meet standardised fit criteria, reducing the need for rework. This makes the tool a reliable component in repetitive production environments where thread accuracy and repeatability determine downstream assembly efficiency.

Efficient chip control and reduced thread defects

The straight-fluted geometry together with ground flanks and a dedicated cutting chamfer for through threads promotes dependable chip evacuation and clean thread flanks. The result is fewer clogged flutes and a lower incidence of surface scoring, which translates into improved first-pass yields and less time spent on corrective operations. For operators and process planners, this means a measurable improvement in machining throughput and reduced indirect costs from scrap or rework.

Broad material compatibility and practical fitting

Specified for use in steels up to 1000 N/mm², this tap covers a wide segment of typical industrial steels encountered in workshop and production settings. The tap’s shank diameter 4.5 mm suits common collet and chuck arrangements on tapping spindles and machining centres; compatibility with standard machine tooling simplifies integration into existing setups. The metric M4 x 0.7 thread form and the adherence to DIN 371B allow straightforward substitution in repair or maintenance work where industry standards are required.

Robust handling, stock reliability and service assurance

Manufactured to a Form B profile and supplied single-packed for traceable handling, the tool balances durability with user-friendly handling. The TiN coating not only improves wear resistance but also eases chip release, supporting longer uninterrupted cycles and less frequent tool changeover. Metav’s distribution and quality-filtering in Emmerich ensure dependable supply for workshops and industrial buyers, while documented specifications assist procurement and quality departments in part selection.
