        Description:

        The Alpha C9STSFM4-20QR is a versatile step drill from the Gold Series, designed to meet the demands of tradesmen requiring precision and efficiency. This metric step drill, with dimensions spanning from 4mm to 20mm across 9 steps, is perfect for drilling through non-ferrous metals, sheet steel, plastic, and stainless steel up to 3mm thick. The tool's 4 flute spiral design and self-starting split point facilitate quick, clean, and accurate drilling without the need for a pilot hole.

        Crafted from premium high-speed steel (HSS M2) with a titanium nitride (TiN) coating, it enhances durability and reduces friction. The drill features a non-slip 1/4 inch quick change shank, fits standard non-hammer action portable power drills, and comes with laser-etched hole sizes for easy identification. Weighing 60g and measuring 165mm in length, it's a practical tool for a wide range of applications.
