RUKO HGB DIN 352 HSS 60° Hand Tap M42 x 4.50 mm

Cutting precise metric coarse threads in tough materials like unalloyed and low-alloyed steels, cast iron, and non-ferrous metals demands a tool that stays sharp and accurate. The RUKO HGB-DIN352-HSS-60°-M42x4,50mm hand tap delivers exactly that, with a ground thread profile and high-speed steel construction for reliable performance in manual threading operations.

Who is it for

Machinists, metalworkers, and maintenance professionals who need to create or repair M42 coarse threads in workpieces up to 800 N/mm² hardness. It is suitable for through-hole and blind-hole threading when used with appropriate tapping procedures.

Main features
