Ruko ULTIMATECUT stepped drill bits, HSS-Co 5, RUnaTEC FLOWSTEP® tip, Ø 9.0–38.0 mm

Efficiency and precision – designed for maximum performance and durability when machining materials up to 4 mm thick. In a single operation, sheets are pre-drilled, reamed, and deburred. Equipped with the innovative FLOWSTEP® tip, this tool allows for quick and secure drilling. With a 5% cobalt content for increased hardness and wear resistance, it is ideal for processing robust materials such as stainless steel and alloyed steels. The RUnaTEC coating ensures perfect heat dissipation, thereby extending the tool's lifespan. Additionally, it allows for higher cutting speeds. It features a 3-flat shank that prevents slipping in the drill chuck and ensures consistently optimal power transmission during the working process.
