RUKO STB-HSS-TX-Gr.2-6-30mm-GNU strojný závitník M6 TiCN

This RUKO machine tap is engineered for efficient thread cutting in through holes. Its spiral point design pushes chips forward, preventing clogging and enabling higher cutting speeds. The TiCN coating reduces friction and heat, extending tool life when machining steels, stainless steels, and cast iron.

Highlights

• Metric coarse thread M6 with 1.0 mm pitch
• Form C spiral point for through-hole applications
• TiCN coating for wear resistance and reduced friction
• HSS-E-PM powder metallurgy steel with cobalt for toughness
• DIN 376 standard, tolerance ISO 2 (6H)

In daily use

The tap cuts clean threads in a single pass, with chips ejected ahead of the tool. Its right-hand cutting direction suits standard machine spindles. The 6.0 mm shank fits common tap holders, and the 4.9 mm square drive ensures positive torque transfer.
