RUKO HGB-DIN2181-HSS-60°-MF-3x0,35 mm strojný závitník

This machine tap is engineered for cutting metric fine threads with a 0.35 mm pitch in M3 holes. Its precision-ground high-speed steel construction and 60° flank angle deliver clean, accurate threads in steel, cast iron, and non-ferrous metals.

Advantages

Ground flutes and a bright finish reduce friction and chip adhesion, extending tool life and improving thread quality. The Form C lead with 2-3 thread lead ensures easy starting and smooth cutting action in through or blind holes.

Suitable for

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