Multi Layer Step Drill Bits are designed for efficient drilling through multi-layered materials, such as laminated metals, plastics, or composite boards. High-speed steel or coated construction ensures durability and long-lasting sharpness, while the progressive step geometry allows multiple hole sizes without tool changes. Tapered shanks ensure secure mounting in drill presses, lathes, or CNC machines, minimizing vibration and producing accurate, clean holes. Ideal for industrial fabrication, prototyping, and specialized workshop applications.
