ZÁVITNÍK M20 DIN-376C R40 (6H) HSSE INOX strojný závitník

The TAP M20 DIN-376C R40 (6H) HSSE INOX is a high-performance machine tap designed for threading through holes in stainless steel and high-alloy steels. Manufactured from HSSE (High-Speed Steel with Cobalt), this tap offers excellent wear resistance and heat tolerance, making it ideal for demanding industrial applications. With a metric coarse thread (M20 x 2.5 mm) and tolerance class 6H, it ensures precise and reliable threading. The spiral point flute design efficiently pushes chips forward, reducing clogging and improving thread quality. The reinforced shank provides stability during high-speed CNC and tapping machine operations.

Advantages

This tap delivers superior performance in stainless steel (INOX) and high-alloy materials. The cobalt content in HSSE enhances hardness and heat resistance, extending tool life. The spiral point geometry enables faster tapping speeds and cleaner threads. The DIN 376C standard ensures compatibility with industry-standard tool holders.
