RUKO HGB DIN 2181 HSS-E 60° strojný závitník M12 x 1,00 mm metrický jemný

Threading through holes in tough steels demands a tap that stays sharp and accurate. The RUKO HGB DIN 2181 HSS-E 60° machine tap with M12 x 1.00 mm metric fine thread is built for that job, cutting clean threads in unalloyed and alloyed steels up to 800 N/mm² and non-ferrous metals.

Who is it for

Machinists and metalworkers who need reliable, precise threads in production or repair work, especially when working with high-strength materials where standard taps wear quickly.

Main features

• HSS-E high-speed steel with cobalt for enhanced wear resistance and heat tolerance.
• Metric fine thread M12 x 1.00 mm with 60° flank angle, tolerance class ISO 2 (6H).
• Form C chamfer (2-3 threads lead) for through holes, right-hand cutting.
• Three flutes for efficient chip evacuation and stable cutting.
• Bright finish for clean cutting action and corrosion resistance.
