Spindle RUKO 255090 9 mm 9 x 32 mm Spiral

The RUKO drill bit, designed in Taiwan, is a specialized tool for deep drilling that stands out for its robustness and precision. Made of stainless steel with a helical tip, this drill bit has a diameter of 9 mm and a total length of 220 mm, suitable for drills with considerable depth, especially in challenging conditions where proper chip evacuation may be limited. Its helical design facilitates waste removal during cutting, reducing the risk of clogging and improving efficiency when working with common materials. The drill bit is built to offer high rotational accuracy, ensuring tight and uniform finishes in every hole. For deep drilling, it is recommended to make small advances and frequent chip extractions to maintain optimal performance and extend the tool’s lifespan. Additionally, the drill bit strictly complies with DIN 1869 standards, ensuring quality and a proper tapered shape for correct assembly and performance. Its bright finish and precise cutting angle (130º at the tip and 40º on the helix) help reduce friction and increase durability, while h8 tolerances guarantee a perfect fit with conventional drilling machines. With these features, the RUKO drill bit is a reliable choice for technicians and professionals who require a durable and efficient tool for deep drilling in stainless steel and other standard materials. This drill bit combines quality materials with a technical design aimed at maximizing durability and precision in industrial or specialized workshop applications.
