RUKO EGB-DIN352-HSSCo-60°-M-3x0,50mm ručný závitník

Threading small metric holes in tough materials demands a tap that stays sharp and cuts cleanly. The RUKO EGB-DIN352-HSSCo-60°-M-3x0,50mm hand tap is built from high-speed steel with cobalt, giving it the edge retention needed for unalloyed and low-alloy steels, cast iron, and non-ferrous metals. Its DIN 352 geometry and 60° thread profile deliver precise M3 threads with a 0.50 mm pitch, while the bright uncoated finish reduces friction for smoother cutting.

Who is it for

Machinists, metalworkers, and maintenance technicians who need a reliable finishing tap for through and blind holes in general-purpose applications. It suits workshops where consistent thread quality and tool life are priorities.

Main features

• HSS-Co material for high hardness and heat resistance

Tips

For best results, drill a 2.5 mm core hole before tapping. Use a suitable cutting fluid to extend tool life, especially in steel. Secure the tap in a proper tap wrench and apply steady, straight pressure to avoid breakage.
