Machine thread tap DIN 374B MF6×0.75 mm, HSS‑Co, straight fluted — TECWERK

The Machine thread tap DIN 374B MF6×0.75 mm is a production tap for machining metric fine internal threads in through holes, suited to use in machine tapping applications and automated equipment

• HSS‑Co construction for increased heat resistance
• Straight flutes for consistent chip evacuation
• Metric fine thread MF to DIN 13, tolerance 6H
• Shank Ø 4.5 mm for secure clamping

Precision and durability for fine internal threads

This tap is manufactured from HSS‑Co, a cobalt‑alloy high‑speed steel that retains hardness at elevated temperatures, enabling reliable performance in demanding production environments. The DIN 374B Form B geometry with straight flutes supports predictable chip formation and evacuation, which is especially beneficial when producing metric fine threads (MF6×0.75 mm) to tolerance 6H. For engineers specifying components with close clearance, the defined tolerance class reduces the need for secondary operations and ensures interchangeability according to international standards.

Efficiency gains through optimized cutting geometry

The combination of flank relief (flank-ground cutting edges) and a reduced chamfer designed for through threads improves thread quality and reduces torque peaks during tapping. These features contribute to longer tool life and fewer breakages under continuous use, translating into measurable productivity benefits on the shop floor. Where materials range up to roughly 1000 N/mm² tensile strength, the tool’s geometry supports stable cutting in steels, malleable cast iron and long‑chipping non‑ferrous metals, lowering the risk of chip jamming and minimising downtime.

Practical integration and workshop guidance

With a shank diameter of 4.5 mm, the tap is adapted for secure retention in collets and toolholders commonly found in CNC tapping spindles and tapping heads. It is intended for machine use rather than manual hand tapping; correct clamping and appropriate feed settings are essential for best results. For mixed‑material production runs the straight‑flute design provides simpler chip control compared with spiral taps, making this tool a pragmatic choice for batch production and automated cells. For specific cutting speeds, feeds or coolant recommendations, consult Metav Werkzeuge’s technical advisors to match the tap to the machining centre and workpiece material.
