RUKO HGB-DIN352-HSS-55° M10 Finishing Tap, Metric Coarse Thread, HSS-G, DIN 352

Machinists and metalworkers use this RUKO finishing tap to cut precise M10 metric coarse threads in unalloyed and low-alloy steels up to 800 N/mm². The HGB-DIN352-HSS-55° is a DIN 352 standard tap made from high-speed steel (HSS-G) with a bright finish, designed for manual or machine tapping operations where accurate thread dimensions are critical.

Why choose it

The HSS-G material provides good wear resistance and cutting performance in steel, while the DIN 352 geometry ensures compatibility with standard tap wrenches and holders. The bright finish reduces friction and helps clear chips from the flutes.

Ideal use cases

• Creating internal M10 threads in steel workpieces
• Repairing or re-threading existing holes
• Use in machine shops, maintenance, and metal fabrication

Good to know

The tap is intended for through-hole or blind-hole threading in unalloyed and low-alloy steels up to 800 N/mm² tensile strength. Use appropriate cutting fluid for best results.
