Kierretappi M10 DIN-371C R40 (6H) HSSE-PM TiCN FAN konekierretappi

Threading through holes in tough materials like stainless steel or superalloys often leads to premature tap wear, poor chip evacuation, and inconsistent thread quality. The TAP M10 DIN-371C R40 (6H) HSSE-PM TiCN FAN machine tap solves these problems with its powder metallurgy HSSE-PM substrate, TiCN coating, and 40° spiral flute geometry designed specifically for efficient through-hole tapping in demanding applications.

Who is it for

This tap is built for CNC machinists, toolmakers, and manufacturing professionals who need reliable, high-performance threading in steels, stainless steels, cast iron, non-ferrous metals, and superalloys. It is ideal for production environments where tool life, thread accuracy, and process stability are critical.

Main features

• Precision ground from HSSE-PM (powder metallurgy high-speed steel with cobalt) for superior wear resistance and toughness.
• TiCN (Titanium Carbonitride) coating reduces friction, prevents built-up edge, and extends tool life in abrasive materials.
• 40° spiral flute (Type C) pulls chips forward and out of the hole, preventing clogging in through-hole applications.
• DIN 371C standard with reinforced shank and 6H tolerance class ensures consistent, gauge-accurate threads.
• Chamfer form C (2-3 threads) provides a balanced lead for easy starting and good thread quality.
• Suitable for a wide range of materials: P (steels), M (stainless steels), K (cast iron), N (non-ferrous), S (superalloys).

Tips

For best results, use a suitable tapping fluid and ensure proper alignment. The 40° spiral flute is ideal for through holes, as it efficiently evacuates chips forward. Always verify the tap is suitable for your specific material and machine setup.
