RUKO HGB-DIN352-HSS-60°-M2x0,40mm handwartelboor

Machinists and metalworkers use this RUKO hand tap to cut clean M2 metric threads in steel, cast iron, and non-ferrous metals. It follows DIN 352 geometry with a 60° flank angle and ISO2 (6H) tolerance, so the threads fit standard M2 fasteners. The HSS body is bright-finished and has three flutes for efficient chip removal in both through and blind holes.
