M8 DIN 376 konekierretappi, HSSE-PM, spiraaliura 45°, 6HX, MASTERTAP

Threading M8 holes in tough materials like stainless steel or alloy steel often leads to premature tap wear, poor chip evacuation, and inconsistent thread quality. The MASTERTAP M8 DIN 376 machine tap solves these challenges with a powder metallurgy HSSE-PM substrate enriched with cobalt, a 45° spiral flute for efficient chip removal, and a 6HX tolerance class for precise, reliable threads.

Who is it for

This tap is built for CNC machinists, toolmakers, and maintenance professionals who regularly cut threads in steel, stainless steel, cast iron, and non-ferrous metals. It is especially suited for production environments where tool life and thread consistency directly impact throughput and part quality.

Main features

• HSSE-PM powder metallurgy high-speed steel with cobalt for superior hardness and wear resistance.
• 45° spiral flute design pulls chips backward, ideal for through holes and many blind hole applications.
• DIN 376 standard with Form C lead-in (2–3 threads) for easy starting and reduced cutting forces.
• 6HX tolerance class ensures a precise fit for metric coarse threads.
• HL high-performance surface treatment reduces friction and improves chip flow.
• Right-hand cutting direction for standard clockwise threading operations.

Tips

Use appropriate cutting fluid for best results. Ensure proper alignment to avoid tap breakage. For blind holes, verify chip evacuation and consider pecking if necessary.
