TECWERK machine tap MF 18×2 mm — HSS‑Co, Form B (DIN 374B)

The TECWERK machine tap MF 18×2 mm is a machine tap for producing metric fine internal threads in steels, malleable cast iron and long‑chip non‑ferrous metals, designed for through‑hole tapping in industrial production

• HSS‑Co for high wear resistance
• Form B straight flute for machine tapping
• 6H tolerance for accurate fit
• Suitable for steels up to 1000 N/mm²

Consistent fine‑thread performance for production use

The combination of HSS‑Co and a 6H tolerance ensures reproducible thread geometry and a secure mating fit in assemblies. In industrial tapping applications, the material selection provides improved wear resistance compared with standard HSS, extending tool life under sequence production. The DIN 374B design supports machine tapping with a straight flute, which stabilises chip formation when cutting through holes and reduces the risk of thread collapse. These attributes translate into fewer rejects and more predictable cycle times on CNC tapping heads or tapping attachments.

Durable cutting geometry that reduces rework

A Form B straight‑flute configuration with flank relief improves evacuation of long chips and promotes cleaner thread flanks, which helps to avoid burrs and reduces secondary operations. The tap's cutter geometry includes a chamfered lead for through‑hole threads, facilitating entry and reducing axial load during engagement. When working with medium‑strength steels (up to approximately 1000 N/mm²), temper cast iron and long‑chip non‑ferrous materials, this tool preserves dimensional accuracy while offering a balance between cutting performance and service life — a rational choice for repetitive production jobs.

Production integration and practical handling benefits

A shaft diameter of 14 mm provides robust clamping for machine tapping spindles and enhances concentricity during high‑speed operations. The tool’s standard compliance with DIN 13 and designation as a metric fine‑thread tap make it straightforward to specify within engineering drawings and procurement lists. The straight‑flute design and HSS‑Co composition reduce the frequency of tool changes, contributing to uninterrupted workflow. For workshops seeking a dependable industrial tap that fits established machining cells, the technical attributes support predictable throughput and simplified tool management.
