RUKO HGB-I DIN 352 HSS 60° M10 x 1.50 mm Left-Hand Hand Tap

For maintenance technicians and machinists who need to cut or repair left-hand metric threads in steel, cast iron, or non-ferrous metals, this RUKO hand tap delivers reliable performance in manual threading operations. The M10 x 1.50 mm fine pitch left-hand tap is manufactured from high-speed steel (HSS) to DIN 352, with a 60° thread angle and ISO 2 / 6H tolerance class, making it suitable for general purpose threading in unalloyed and alloyed steels up to 800 N/mm².

Why choose it

The HSS construction provides good wear resistance and cutting performance for manual threading tasks. The left-hand thread direction is essential for applications requiring reverse-threaded holes, such as certain rotating components or adjustment mechanisms. The bright finish offers a clean surface without additional coatings, suitable for general workshop use.

Ideal use cases

• Cutting new left-hand metric threads in through or blind holes
• Repairing damaged M10 x 1.50 left-hand threads
• Manual threading in maintenance, repair, and small batch production
• Working with unalloyed and alloyed steels, cast iron, and non-ferrous metals

Good to know

This tap is a single piece, not a set. It is designed for manual operation with a suitable tap wrench (not included). The square shank provides a secure grip in standard tap handles. The DIN 352 standard ensures dimensional compatibility with common tooling.
