RUKO HGB-DIN352-HSS-60°-1/4 ručný závitník M1.4 x 0,3 mm

This RUKO hand tap is engineered for precise threading in small-diameter holes. Unlike standard taps, it features a 60° chamfer lead and complies with DIN 352, ensuring reliable thread cutting in unalloyed and low-alloy steels as well as non-ferrous metals.

Highlights

• Metric thread M1.4 with 0.3 mm pitch
• High-speed steel (HSS) for durability
• Straight flute design with 3 flutes
• Right-hand cutting direction
• ISO 2 (6H) tolerance class

In daily use

The bright, uncoated finish reduces friction, while the 34 mm overall length and 7 mm thread length make it suitable for shallow holes. The 1.6 mm shank diameter fits standard tap wrenches, and the 1.2 mm square drive ensures secure holding.
