Machine tap MF27×1.5 HSS‑Co DIN 374B — TECWERK, Form B, 20 mm shank

The Machine tap MF27×1.5 HSS‑Co DIN 374B is a straight‑fluted Form B tap designed for producing precise metric fine threads in through‑hole applications on medium‑strength steels and long‑chipping non‑ferrous metals

• HSS‑Co, Form B, straight flutes, flanks relieved
• Metric ISO fine thread MF27×1.5, DIN 13, tolerance 6H
• Through‑hole chamfer for clean thread start
• Suitable for steels up to 1000 N/mm² and non‑ferrous

High precision where thread tolerance matters

The use of HSS‑Co (cobalt‑alloyed high‑speed steel) and the 6H tolerance field make this tap a reliable choice when reproducible fits and assembly tolerances are required. The tool’s Form B geometry with relieved flanks reduces radial cutting forces, which supports consistent thread form and helps maintain gauge tolerances over long production runs. For workshops transitioning from hand taps to machine tapping, this specification ensures compatibility with standard metric ISO fine‑thread requirements and DIN 13 nomenclature while offering improved wear resistance compared with plain HSS.

Optimised for through‑hole tapping and mixed materials

Equipped with a dedicated through‑hole chamfer, the tap initiates threads cleanly in through holes and evacuates chips effectively during continuous operation. The geometry and material are specified for use in steels up to 1000 N/mm², malleable cast iron and long‑chipping non‑ferrous metals, making it suitable for diverse components from structural brackets to lightweight housings. The 20 mm shank supports secure clamping in machine holders, stabilising concentricity and contributing to reliable runout control — a key factor for achieving uniform thread quality across batches.

Practical integration into workshop and production environments

Designed as a machine tap for standard tool spindles and holders, the item supports efficient cycle planning and predictable maintenance intervals. The straight‑flute cut combined with the peel‑style chamfer reduces the need for frequent tool changes when processing compatible materials, which benefits throughput and total cost of ownership. When selecting cutting speeds and feeds, aligning parameters with material machinability and coolant use will extend tool life; the tap’s specification simplifies this decision by clearly defining suitable material classes and maximum recommended strength.
