Macho de roscar a máquina M8 DIN 371B (6HX) HSS-PM EL-CUT

Precision machine tap for M8 metric coarse threads, engineered from powder-metallurgy high-speed steel with EL-CUT coating for exceptional performance in through-hole threading operations.

Advantages

The HSS-PM substrate delivers superior toughness and wear resistance compared to conventional HSS, while the EL-CUT coating reduces friction and heat build-up, extending tool life and improving thread quality. The spiral point (Form B) geometry efficiently pushes chips forward, making it ideal for through holes in a wide range of materials.

Suitable for

• Through-hole threading in steels, stainless steels, and non-ferrous metals
• General-purpose machining, maintenance, and production environments
• Use with tapping machines, CNC machining centres, or manual tapping operations
