RUKO HGB-DIN352-HSSCo-60°x0.40mm Hand Tap M2.5 x 0.40 HSS-Co DIN 352

Precision-ground from cobalt-alloyed high-speed steel, this RUKO hand tap delivers a 60° flank angle and ISO 2 (6H) tolerance for clean, accurate M2.5 x 0.40 metric threads in materials up to 1000 N/mm² tensile strength.

Overview

The RUKO HGB-DIN352-HSSCo-60°x0,40mm is a straight-flute hand tap manufactured to DIN 352. Its HSS-Co substrate withstands the heat and abrasion of general-purpose threading, while the bright uncoated finish reduces chip adhesion. With three flutes and a right-hand cut, it suits both through and blind holes.
