The 15-piece set is clearly arranged and easy to transport in a hard-wearing industrial case made of robust metal. A chip jam and the associated obstruction of the cutting process is therefore effectively prevented, ensuring perfect quality of the tapped holes. Thanks to the straight flute, the chips are rolled tightly when cutting through holes and transported away in the cutting direction. The absolutely high-performance HSS-G taps according to DIN 352 have a peel cut of form B with a medium 4 - 5 thread lead, which reduces the stress on the cutting edges, especially when machining materials with a high strength, thus additionally optimising the already very long tool life. The point angle of the precise core hole drills is 118°, whereupon the drill point can be optimally centred in the material without slipping. The profile-ground HSS-G core hole twist drills according to DIN 338 have normal spirals with a spiral twist of type N, which ensure optimum chip removal and enable smooth drilling of the core holes. Since one lever of the tap wrench can be unscrewed, it can be used in narrow places and can be stored in the cassette to save space. The comprehensive tap set is complemented by the adjustable tap wrench according to DIN 1814, which consists of a housing made of corrosion-resistant die-cast zinc and specially hardened clamping jaws that ensure optimum holding of the various taps with square shank. As a result, the required feed force during drilling and cutting is significantly reduced, making even the machining of tough plastics such as acrylic glass or steels easy. Since the seven taps, as well as the seven core hole taps, are ground with the highest precision, they are characterised by extreme sharpness.

The long-lasting HSS-G taps, just like the matching HSS-G core hole twist taps, are made of high-quality alloyed high-performance high-speed steel with a complex profile grinding and have an enormous service life and tempering resistance.
