The Guhring No 17 is a professional-quality 19-piece HSS drill bit set with titanium nitride coating, designed for precise drilling in ferrous metals and cast iron materials. This comprehensive set covers diameters from 1.0mm to 10.0mm in 0.5mm increments, providing excellent versatility for engineering and metalworking applications. Manufactured in Germany using high-grade German steel, these Type N DIN 338 twist drills feature a 118° point angle and straight shanks for reliable performance. The TiN coating significantly enhances wear resistance and reduces friction during drilling, extending tool life when working with demanding materials. With h8 tolerance and a machining depth capability of approximately 5 times the diameter, these drills deliver professional accuracy for steel fabrication, precision engineering, and metal machining tasks. The set is optimally suited for drilling steel, high alloyed steel, grey cast iron, spheroidal graphite iron, and malleable cast iron. It also offers limited suitability for aluminium and other non-ferrous metals. All drill bits are supplied in a convenient storage case for easy organisation and transportation between job sites.
