Machine tap DIN 374C MF27×1.5 HSS‑Co 6H – TECWERK

The Machine tap DIN 374C MF27×1.5 HSS‑Co 6H is a right‑hand, fine‑pitch ISO metric tap engineered for producing blind threads in steels, temper cast iron and long‑chip non‑ferrous metals

• HSS‑Co for enhanced wear resistance
• 40° right‑hand spiral for chip control
• Form C with chamfered flanks
• Shank Ø 20 mm for secure mounting

Precision threads with extended tool life

The HSS‑Co composition combined with the 6H tolerance delivers a reliable balance between hardness and toughness, which extends tool life under continuous use. The tap is manufactured to ISO fine‑pitch standards so that threads meet consistent dimensional requirements; this reduces rework and inspection effort on the shop floor. Measurable production benefits include fewer rejects and steadier cycle times when machining metric fine threads.

Safer machining in blind holes and improved chip evacuation

Designed with a 40° right‑hand spiral and Form C geometry, the tool promotes axial chip evacuation, which is particularly important for blind holes where chip buildup risks tap breakage. The chamfered flanks improve thread entry and reduce cutting forces, while the shank Ø 20 mm ensures stable clamping in machine holders. These features together lower the likelihood of tool failure and minimise unscheduled downtime during batch runs.

Versatile application and workshop integration

Suitable for use in steels up to ca. 1000 N/mm², temper cast iron and long‑chip non‑ferrous metals, the machine tap integrates into standard production environments without special requirements. The robust construction supports automated tapping cycles and repeated use in industrial settings. For procurement and stocking strategies, the tool is a pragmatic choice for workshops seeking consistent performance and simplified supplier management; Metav Werkzeuge’s quality filter further ensures dependable supply logistics and product consistency.
