The STIER HSSG tap set is a comprehensive solution for professional applications in the production and machining of internal and external threads. With a selection of taps for metric sizes from M3 to M12 and a ground design, this 45-piece set is aimed at users who value precision and durability. Also included are dies for the same sizes of the metric system, which are used to create precise external threads. The set is complemented by high-quality, ground core hole twist drills, which precisely drill individual core hole sizes in the range from 2.5 to 10.2 mm diameter and thus provide the basis for thread production. For optimum handling, the holding tools are made of lightweight yet break-resistant powder metal. A chrome-plated ratchet with hardened clamping jaws and countersunk centring eye helps to align the taps easily and precisely. With a total weight of 4.18 kg, the set can be used for a wide range of applications. The entire set is supplied in a sturdy, industrial metal case, which ensures tidiness and safe transport. Each tool is stored safely and neatly thanks to its own holders and is therefore quickly to hand.
