RUKO HGB-DIN352-HSS-55° M5 macho de roscar manual, HSS-G, DIN 352, rectificado, 3 ranuras

Cutting internal metric threads by hand can be slow and imprecise, but this RUKO taper tap solves that with a ground HSS-G body and DIN 352 geometry for clean, accurate M5 threads in unalloyed and low-alloyed steels, cast iron, and non-ferrous metals.

Who is it for

Machinists, metalworkers, and maintenance technicians who need reliable hand tapping of M5 coarse threads in common materials.

Main features

• Ground from HSS-G high-speed steel for durability and sharp cutting edges.
• Conforms to DIN 352 for standard metric coarse thread dimensions.
• Taper tap (Vorschneider) with 3 straight flutes for easy chip evacuation.
• 60° flank angle and ISO 2 (6H) tolerance for precise thread fit.
• Square shank for secure grip in tap wrenches.
