RUKO HGB-DIN352-HSS-60°-M8x1.25mm ručný závitník

The RUKO HGB-DIN352-HSS-60°-M8x1.25mm hand tap is a precision threading tool engineered for creating metric coarse threads in through-holes and blind holes. Unlike machine taps that require powered equipment, this hand tap is designed for manual operation, giving you full control over thread cutting in general purpose steels and non-ferrous metals. Its straight flute design and 60° thread angle ensure clean chip evacuation and accurate thread profiles, while the HSS construction provides the durability needed for repeated use.

Highlights

• Metric coarse thread M8 with 1.25 mm pitch
• High-speed steel (HSS) for long tool life
• Straight flute, right-hand cutting direction
• DIN 352 standard for hand taps
• Bright surface finish
