RUKO HGB-DIN352-HSS-55° Metric Coarse Thread Finishing Tap, M10 x 1.5 mm, DIN 352, HSS, Bright Finish, Square Drive

Cutting precise internal threads in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals requires a tap that holds its edge and follows the DIN 352 standard. This RUKO finishing tap delivers clean, accurate M10 x 1.5 mm metric coarse threads with a right-hand direction and ISO 2 (6H) tolerance class.

Who is it for

Machinists, metalworkers, and maintenance technicians who need a reliable finishing tap for general-purpose threading in materials up to 900 N/mm² hardness. It suits workshops, production lines, and repair jobs where consistent thread quality matters.

Tips

Use a suitable tapping lubricant for the workpiece material to extend tool life and improve thread finish. Ensure the tap is aligned perpendicular to the hole and apply steady, even pressure while turning. For blind holes, clear chips regularly to prevent binding.
