RUKO HGB-DIN352-HSS-60°-M11x1.50mm Hand Tap

Creating precise internal threads in metal requires a tool that can withstand high cutting forces while maintaining exact thread geometry. The RUKO HGB-DIN352-HSS-60°-M11x1.50mm hand tap is engineered for reliable thread cutting in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals. Made from high-speed steel with a 60° thread angle, this finishing tap produces clean, accurate M11 x 1.50 mm metric ISO threads to tolerance class 6H. Its three-flute design efficiently clears chips, while the square shank provides a secure grip in tap wrenches. With a thread length of 25 mm and an overall length of 80 mm, it is suitable for both through-hole and blind-hole applications.

Who is it for

This hand tap is ideal for machinists, metalworkers, and maintenance professionals who need to cut or restore internal threads in common metals. It is particularly suited for repair work, prototype manufacturing, and small-batch production where hand tapping is preferred.

Tips

Use a suitable cutting fluid to extend tool life and improve thread finish. Ensure the tap is aligned perpendicular to the workpiece to avoid thread damage. For blind holes, periodically reverse the tap to break chips.
