Label:Yes [Practical for Thin Metal Work] This step drill is a practical choice for work where thin steel, aluminum, or plastic enclosures and panels need clean, accurate holes. [Wide Hole Range] A single drill bit can create hole sizes from 4 mm (0.16 in) to 12 mm (0.47 in), reducing the need for frequent bit changes. [High Hardness HSS] The step drill bit is made from high speed steel, delivering impressive hardness and strong wear performance for long lasting use. [Ideal for Softer Materials] It is most commonly used on softer materials such as thin iron sheet, aluminum, PVC, and wood boards up to 4 mm (0.16 in) thick. [Titanium Coated Surface] The surface is coated with titanium, giving the drill bit a polished gold appearance that resists fading over time.
