M5x0.8mm Thread Tap DIN 371C GG HSS-Co TiCN Coated 6HX For Cast Iron Through/Blind Holes - TECWERK

Take advantage of the combination of HSS‑Co construction, a TiCN hard‑coating and the precise 6HX tolerance class to achieve consistent metric thread production in cast iron components; order the tool directly via Metav Werkzeuge or contact our consultants for application advice.

TECWERK machine tap DIN 371C GG M5 x 0.8 mm — HSS‑Co, TiCN, 6HX

The Machine tap DIN 371C GG M5 x 0.8 mm is a straight‑fluted, cobalt high‑speed steel tap designed to produce precise metric ISO threads in a range of cast iron materials.

• HSS‑Co solid for high wear resistance
• TiCN coating reduces friction and extends life
• Straight flutes for reliable chip removal
• Tolerance 6HX for precise metric threads

Consistent thread quality for cast‑iron workpieces

The tool is engineered to deliver repeatable, ISO‑compliant threads in cast iron grades. Built from HSS‑Co, the tap maintains cutting edge stability under thermal load, while the TiCN layer lowers adhesion and cutting temperature; together these features reduce tool wear and increase the number of good parts per cycle. Specified to DIN 371C and to DIN 13 Part 1 thread form, the 6HX tolerance class provides a slip‑fit thread suitable for general engineering applications, which helps to avoid time‑consuming rework and ensures interchangeability in assemblies.

Coating and geometry that improve process reliability

The combination of a TiCN coating with a straight‑flute geometry benefits both surface quality and chip control. The coating reduces friction at the cutting edge, improving resistance to built‑up edge and enhancing tool life under interrupted cuts, while the straight flutes allow controlled evacuation of chips from blind and through holes. Flanks that are relief‑ground reduce radial pressure and aid thread form accuracy, making the tool particularly suitable for repeated production runs where consistent cycle times and reduced machine stoppages are priorities.

Practical features for efficient workshop use

Key design details translate directly into shop‑floor advantages: the shank Ø 6 mm permits secure clamping in standard holders, and the white ring identification speeds tool selection across mixed toolkits. The tap is suitable for both through and blind holes, and is optimised for grey cast iron, graphite cast iron and malleable cast iron, offering a targeted solution for foundry and machining shops. By specifying the correct form and tolerance, tool planners can simplify inventory and rely on predictable assembly fitment.

Integration into production and quality workflows

Adopting this machine tap supports leaner machining processes: longer tool life and reduced thermal deformation lower scrap rates, while compliance with recognised standards (thread form and tolerance) simplifies quality assurance and documentation. The straightforward geometry and robust coating make the tool an economical option for series production and maintenance operations alike, delivering measurable productivity gains without requiring specialised machine settings.
