RUKO Helical Drill Bit

The RUKO drill bit is made of high-speed steel (HSS), a material known for its high hardness and wear resistance, making it particularly suitable for demanding and prolonged drilling tasks. This model features a 52 mm diameter and a total length of 225 mm, dimensions that guarantee appropriate depth and cutting capacity for industrial applications and professional workshops. It has a helical design with a spiral angle between 20º and 30º, optimized to effectively evacuate chips and prevent overheating during drilling. Its 118º cutting angle ensures precise penetration and uniform performance even on materials of varying hardness. The drill bit is designed for taper shank drilling, facilitating its attachment in standard chucks with great stability and safety. It is recommended for a wide range of materials, including alloyed or unalloyed steel and cast steel with a tensile strength of up to 900 N/mm², cast irons (gray, malleable, ductile, and pressure die-cast), sintered iron, aluminum alloys, bronze, brass, nickel silver, and graphite cast iron. The dimensional tolerance is h8, ensuring diameter precision and fit with machined parts. Additionally, its bright surface and right-hand cut indicate optimal finishing, extending the tool's lifespan. The product is presented in a translucent plastic case with a blue background label, facilitating its storage and transport while protecting the drill bit. This RUKO drill bit stands out for its robustness and high resistance to breakage, positioning itself as a reliable tool for standard drilling tasks on common metal materials, ideal for professionals seeking precision, durability, and versatility.
