If you like to take care of every detail in your home and own the latest products that will make your life easier, purchase Spindle RUKO Spiral at the best price. The RUKO drill bit is made of high-speed steel (HSS), a material known for its high hardness and wear resistance, making it especially suitable for demanding and prolonged drilling tasks. This model features a 52 mm diameter and a total length of 225 mm, dimensions that ensure adequate 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 excessive heating during drilling. Its 118º cutting angle contributes to precise penetration and consistent performance even in materials with varying hardness. The drill bit is designed for Morse taper drilling, facilitating secure mounting in standard chucks with high stability and safety. It is recommended for use on a wide range of materials, including alloyed and non-alloyed steel and cast steel with strength up to 900 N/mm², cast irons (gray, malleable, nodular, and ductile), sintered iron, aluminum alloys, bronze, brass, nickel silver, and graphite castings. The dimensional tolerance is h8, ensuring precision in diameter and fit with machined parts. Additionally, its bright surface and right-hand cutting direction indicate an optimal finish that extends tool life. The product comes in a translucent plastic case with a blue background label, facilitating storage and transport while keeping the drill bit protected. This RUKO drill bit stands out by combining robust quality with high breakage resistance, positioning it as a reliable tool for standard drilling tasks in common metal materials, ideal for professionals requiring precision, durability, and versatility.
