Machine tap DIN 371C GG M4×0.7 HSS‑Co TiCN 6HX TECWERK

The machine tap DIN 371C GG M4×0.7 HSS‑Co TiCN 6HX TECWERK is a straight‑flute machine tap designed for metric ISO threads in cast‑iron components and suitable for both through and blind holes.

• HSS‑Co for improved toughness and wear resistance
• TiCN coating for reduced friction and longer life
• Straight flutes with relieved flanks for reliable chip evacuation
• Tolerance field 6HX for accurate, standardised threads

Consistent, standardised threads for reliable assemblies

The primary advantage is repeatable, standard‑conformant threading: the tool produces metric ISO threads in accordance with DIN 13 (sheet 1) and the specified tolerance field 6HX ensures threads meet industrial fit requirements. For production environments where interchangeability and assembly reliability matter, the tolerance class delivers predictable clearance and engagement. The use of the DIN 371C form positions the tap for general‑purpose machine tapping while the M4×0.7 designation defines the exact thread geometry that matches common fasteners in mechanical assemblies.

Longer operating life and smoother cutting performance

Built from HSS‑Co, the tap combines high‑temperature strength with fracture resistance, making the tool more tolerant of interrupted cuts and harder workpiece surfaces. The TiCN coating reduces surface friction and helps prevent adhesive wear, which together lower wear rates and extend tool life in series production. The straight flutes and relieved flanks (flank relief) aid chip flow and reduce torque peaks; the white ring marking supports quick identification at the machine. These characteristics translate into fewer tool changes and more productive machining cycles.

Designed for cast‑iron applications and mixed hole types

The geometry and coating are optimised for machining in cast iron, including grey cast iron, graphite cast iron and malleable/tempered cast iron, and the tool is specified for both through and blind holes. The form C (DIN 371C) chamfer and the Type GG straight‑fluted design make it suitable where chip control and insertion depth vary. The shank Ø 4.5 mm provides the connection needed for common collet chucks and holders used in machine shops. If the application involves mixed materials or unusual hole conditions, consultation on cutting data and clamping is advisable to maximise life and thread quality.

FAQ

What materials can this tap machine?
The TECWERK machine tap (M4×0.7, SKU 2000867422NW) is specified for use in cast‑iron materials, including grey cast iron, graphite cast iron and tempered/malleable cast iron.

Is this tap suitable for blind holes?
Yes, the tool is designed for both through and blind holes; the Form C (DIN 371C) geometry supports reliable entry and exit behaviour in varied hole depths.

What benefit does the TiCN coating provide?
The TiCN coating on the TECWERK tap reduces friction and improves wear resistance, which helps maintain thread quality over longer production runs.

What does the tolerance 6HX mean for assembly?
Tolerance class 6HX indicates a standard metric thread fit with controlled clearances; this provides predictable assembly behaviour and compatibility with standard M4 fasteners.

What shank size is required for holders?
The tool has a shank Ø 4.5 mm, which fits common collets and holders used on machine tapping spindles.
