RUKO HGB-DIN5157-HSS-55°-Rp-1-1/2 pijptap

This RUKO pipe thread tap stands out for its precision-ground HSS construction and DIN 5157 compliance, delivering clean, accurate Rp 1 1/2-inch parallel threads in tough materials. Unlike generic taps, it is engineered for right-hand threading with a 55° thread angle, ensuring compatibility with standard pipe systems.

Highlights

• High-speed steel (HSS) for durability and long tool life
• Straight flute design for efficient chip evacuation in through holes
• Bright uncoated finish reduces friction and resists corrosion
• Four flutes provide stable cutting and smooth thread finish
• Precision ground to DIN 5157 for reliable thread quality

In daily use

Ideal for creating parallel pipe threads in unalloyed and alloyed steels, cast iron, and non-ferrous metals. The tap's 160 mm overall length and 45 mm thread length offer ample reach, while the 35.5 mm shank diameter fits standard tap holders. The 28 mm square drive ensures secure torque transfer during manual or machine tapping.
