Drill set with taps M3-M12 in a plastic case, HSS type B, RUKO. 

The machine tap consists of heavy-duty high-speed steel. For through threads and bottoming threads in unalloyed steels up to a strength of 800 N/mm², malleable.The thread is cut in one operation. High speed tool steel, best known as 'high speed steel', refers to a group of alloyed tool steels with up to 2,06% carbon content and up to 30% proportion of alloying elements such as tungsten, molybdenum, vanadium, cobalt, nickel and titanium. HSS materials are characterised by great hardness, wear resistance and heat resistance up to 600° C. The HSS tools are less sensitive to shocks and vibrations, which sometimes quickly lead to breaks in the harder cutting materials.

High-performance standard twist drills made of durable high-speed steel. The drills have high-quality factory sharpening and precise concentricity (centering along the axis). These drills have good centering properties and do not require much pressure when working with them. An excellent professional set for various types of work, both industrial and amateur.
