        Alpha 9STSFM4-12S | Gold Series Step Drill 4-12mm 9 Steps

        Description:

        The Alpha 9STSFM4-12S Gold Series Step Drill is a specialized tool crafted for precision drilling across a range of materials. Designed for tradesmen, this 2-flute spiral step drill spans 4-12mm in 9 distinct steps, enabling precise drilling and deburring in one seamless process. It's the ideal tool for working with non-ferrous metals, sheet steel, plastic, and stainless steel up to 3mm thick. The drill's compatibility with non-hammer action portable power drills and its self-starting split point eliminates the need for a pilot hole, simplifying your work.

        Smooth cutting is guaranteed by the 2-flute design, while the TiN(Titanium nitride) coating enhances heat resistance and lubricity, significantly prolonging the tool's lifespan. Constructed from premium HSS M2 material and equipped with a shank featuring three flats to prevent slippage, this drill ensures durability and reliable performance. The laser-etched holes on the drill offer clear visibility for step sizes, enhancing accuracy for every job.

        Features:

        • 9-Step Sizes: Provides versatility with steps from 4 to 12mm.
        • Efficient Design: Drills and deburrs simultaneously, saving time and effort.
        • Enhanced Durability: TiN coating for reduced heat and improved lubricity.
        • Ease of Use: Self-starting split point for pilot hole-free drilling.
        • Premium Material: Made from high-quality HSS M2 for extended usability.
        • Stable Performance: Shank design prevents slippage in the drill chuck.
        • Clear Step Identification: Laser-etched holes for precise drilling.
