Macho de roscar à máquina RUKO MGB-DIN371-HSSCo-vap.-M4x0,70mm, HSS-E Co, VAP, M4 x 0,70 mm, DIN 371

Machine tap for cutting metric coarse threads in through holes, featuring high-speed steel with cobalt (HSS-E Co) and vaporized surface treatment for enhanced durability.

Advantages

HSS-E Co material provides high heat resistance and wear resistance, suitable for machining tough materials. The vaporized (VAP) surface treatment improves chip evacuation and reduces friction, extending tool life. Reinforced shank design offers increased rigidity and stability during tapping operations.

Suitable for

• Through hole threading in steel, stainless steel, and other machinable metals
• Use with tapping machines or CNC machining centers
• Industrial manufacturing and maintenance applications
