RUKO HGB-DIN352-HSS-60°-M2.5x0.45mm ručný závitník

The RUKO HGB-DIN352-HSS-60°-M2.5x0.45mm is a precision hand tap engineered for cutting metric threads in unalloyed and alloyed steels up to 900 N/mm². Its high-speed steel construction and straight flutes ensure reliable chip evacuation and long tool life, while the right-hand cutting direction and ISO 2 (6H) tolerance class deliver consistent thread quality for general-purpose threading tasks.

Highlights

• Metric standard thread M2.5 with 0.45 mm pitch
• High-speed steel (HSS) for durability and heat resistance
• DIN 352 second tap (intermediate) for progressive thread cutting
• Straight flutes with 3 flutes for efficient chip removal
• Bright uncoated surface for clean cutting edges

In daily use

This hand tap is ideal for creating or repairing internal threads in metal components. The second tap profile allows for gradual thread formation, reducing the risk of tap breakage. Its compact dimensions—45 mm total length and 11 mm thread length—make it suitable for through-hole and blind-hole applications in confined spaces. The square drive size of 2.1 mm fits standard tap wrenches, ensuring secure torque transfer.
