Features: Machine tap with overflow shank and right-hand spiral flutes at 35° RSP for blind hole threads. Machine tap made of high-performance high-speed steel. Suitable for blind hole threads in unalloyed, low-alloyed, and alloyed steels up to 1200 N/mm² strength and cast iron. The thread is cut in a single operation. The TiAlN wear-resistant coating increases the surface hardness to approximately 3,500 HV. Titanium aluminum nitride is a chemical compound of the three elements titanium, aluminum, and nitrogen. TiAlN is a metallic hard material typically black-violet in color. Advantages: The TiAlN coating allows cutting tools to operate dry, eliminating the need for cooling. Higher hardness, very low coefficient of friction, optimal tool life.
