RUKO HGB-DIN352-HSS-55° handdraadtap G 1/8 inch HSS-G DIN 352

Precision-ground HSS-G hand tap for G 1/8" BSPP threads with a 55° thread angle, engineered to DIN 352 for reliable manual thread cutting in steels and non-ferrous metals.

Overview

The RUKO HGB-DIN352-HSS-55° is a high-performance hand tap manufactured from HSS-G (high-speed steel, ground) for superior cutting accuracy and durability. It conforms to DIN 352, ensuring dimensional consistency and compatibility with standard tapping operations. The tap features a G 1/8" British Standard Pipe Parallel (BSPP) thread with a 55° thread angle and 28 threads per inch, making it ideal for creating parallel pipe threads that seal on the thread flanks. With a right-hand cutting direction and three flutes, it efficiently evacuates chips while maintaining thread quality. The bright surface finish reduces friction and improves chip flow. This tap is designed for manual threading in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals.
