Material and construction Speed Steel material: crafted from durable speed steel for longlasting performance. It is suitable for cutting through metal, wood, and plastic. Coating and efficiency Titaniumplated coating: titanium plating provides enhanced wear resistance and reduces friction, contributing to smoother and more efficient drilling. Size and compatibility options Versatile size options: available in size ranges 25, 510, 1015, and 1520 to accommodate different hole sizes and drilling tasks with good accuracy. Multiple shank diameter options: shanks available in 6 mm, 8 mm, 10 mm, and 12 mm to fit a wide range of drilling machines and applications. Key benefits Builds reliability across multiple materials, delivering consistent countersinking performance. Reduces tool wear and heat buildup through titanium plating, extending bit life. Provides flexible compatibility with various drill rigs and hole specifications due to multiple size and shank options. Enables clean, flush screw heads for a professional finish in wood, metal, and plastic projects. Use scenarios Woodworking and cabinetry: countersinking screws for a flush, professional finish on furniture and builtin installations. Metal fabrication: preparing counterbored holes in metal sheets for flushmounted fasteners. Plastic enclosures and assemblies: countersinking screws in plastic components to prevent snagging and ensure smooth edges.
