Innovation for improved drilling quality
The RUKO HSS spiral-grooved step drill set offers an innovative solution for precise drilling in various materials. With FLOWSTEP technology, this set enables seamless transitions between different diameters, resulting in improved drilling quality. Each step is equipped with a special relief that ensures a controlled and smooth drilling process.
Made from high-alloy HSS tool steel, this set offers outstanding performance and durability. The three-sided shaft ensures optimal stability during drilling and facilitates retraction when drilling through sheet metal. The deep-ground and spiral-shaped chip groove guarantees absolute smoothness and high cutting performance. This efficiently removes non-breaking chips, which reduces the formation of built-up edges and cold welding.
3 step drills, 1x ⌀ 4-12 mm, 1x ⌀ 4-20 mm, 1x ⌀ 4-30 mm
The step drill set is versatile and ideal for materials such as steel, aluminum, brass, plastics and secondary applications such as bronze and cast iron. With its high-performance high-speed steel and the cross-ground on the drill tip, it ensures good centering and low feed force.
