Cimco 203051 macho de roscar a máquina M4 con ranura recta HSS-E DIN 371

Machine tap with straight flutes for cutting metric M4 threads in through holes. The HSS-E cobalt alloy provides high wear resistance and heat hardness, enabling reliable thread production in unalloyed and alloyed steels, cast iron, and non-ferrous metals up to 800 N/mm² tensile strength.

Advantages

Straight flute geometry directs chips forward, preventing clogging in through-hole applications. The ISO 2 (6H) tolerance class ensures threads fit standard metric fasteners. Precision-ground threads and a 3.4 mm square drive allow secure holding in tap wrenches or machine holders.

Suitable for

• Unalloyed and alloyed steels
• Cast iron
• Non-ferrous metals
• Through holes
