Machine tap set DIN 371/376 C M3–M12, 14 pcs – HSS‑Co5 by Ruko

Machine tap set DIN 371/376 C M3–M12 for professional thread cutting in mechanical workshops and production lines

• HSS‑Co5 for extended tool life
• Covers metric taps M3–M12
• Complies with DIN 371/376 standards

Reliable tapping performance for production

The machine tap set DIN 371/376 is designed to deliver repeatable results in serial production and workshop use. The use of HSS‑Co5 (high‑speed steel with cobalt) increases hot hardness and wear resistance, which maintains cutting geometry under load and extends tool life. This results in fewer tool changes and more consistent thread profiles, improving throughput. Where faster cycle times are required, the set's material properties support higher cutting temperatures without premature dulling.

Accuracy and compatibility across metric threads

Conforming to DIN 371/376 ensures compatibility with established metric thread standards, so mating components meet tolerance and fit requirements. The set covers taps from M3 to M12, which addresses a wide range of common fastening needs in metalworking and assembly. Included spiral drill sizes match the recommended pilot holes for each tap, simplifying process planning and reducing the risk of incorrect drill selection. Clear standardisation reduces rework and supports quality assurance procedures.

Durability, practical design and straightforward use

The cutting material HSS‑Co5 provides a balance between toughness and hardness, making the tools suitable for interrupted cuts and varied workpiece steels. The kit contains a mix of through‑machine taps and corresponding twist drills (Ø 2.5 / 3.3 / 4.2 / 5.0 / 6.8 / 8.5 / 10.2 mm), enabling one‑stop preparation from drilling to threading. The combination reduces setup complexity and saves time during job changes. For users with limited technical background, the set’s adherence to normative drill‑to‑tap pairings simplifies procedure selection and lowers the learning curve.

Supply assurance and partnership benefits

Sourcing through Metav brings the practical advantage of a European distribution and quality filter: fast, reliable delivery from Emmerich and access to technical guidance if process parameters need fine tuning. Metav’s range and experience mean the kit is supported within a broader offering of measuring and maintenance equipment, allowing buyers to standardise tooling and inspection workflows. This partnership reduces procurement complexity and supports consistent workshop quality.
