RUKO HGB Set 2-Piece DIN 2181 Metric Fine Hand Tap Set M7 x 0.75 mm HSS

Precision-ground hand tap set for cutting metric fine threads M7 x 0.75 mm in general purpose steels and non-ferrous metals. The set includes a taper tap for starting and a bottoming tap for finishing blind holes, both made from bright high speed steel (HSS) to DIN 2181 with ISO 2 (6H) tolerance class.

Overview

This RUKO hand tap set is engineered for manual thread cutting in through and blind holes. The two-piece configuration covers the complete threading process: the taper tap gradually forms the thread profile, while the bottoming tap ensures full thread depth close to the hole bottom. The tools are manufactured to DIN 2181 and feature a right-hand cutting direction.
