The Ruko-204305 twist drill bit is a high-performance tool designed to meet the demands of drilling in a wide variety of materials. With a tapered shank according to DIN 345, this drill bit is ideal for standard drilling applications, offering high tensile strength and exceptional performance. Its 118° cutting angle and 20-30° spiral angle ensure efficient and precise cutting, while its bright surface reduces friction and improves durability.
This drill bit is suitable for drilling steel and cast steel, both alloyed and non-alloyed, with a tensile strength of up to 900 N/mm².
It is also effective on gray, malleable, and nodular cast irons, as well as sintered iron, nickel silver, graphite cast iron, aluminum alloys, bronze, and brass.- Diameter: 30.50 mm
