Cobalt Blacksmith Drill Reduced Shank (1/2"/12.7mm). This drill bit is designed for heavy-duty applications requiring strength, heat resistance, and precision. It has an overall length of 150mm and a flute length of 78mm for excellent chip clearance and deeper drilling. Manufactured to DIN 338 standard from high-grade cobalt alloy steel, it offers exceptional durability and performance in high-temperature drilling. Suitable for drilling into stainless steel, chrome-nickel alloys, acid-resistant steels, high-tensile steels, heat-resistant steels, cast iron, hardened or work-hardened steel, tool steel, manganese steel, titanium and titanium alloys, bronze, nickel-based alloys, and other difficult-to-machine ferrous and non-ferrous metals. It is perfect for machinists, mechanics, metalworkers, and hobbyists who need to cut or repair threads with confidence and accuracy. Crafted from premium HSS cobalt material, these drill bits offer superior hardness and heat resistance, making them ideal for drilling tough materials. They provide consistent performance and extended tool life, even in demanding tasks. The precision-ground, 135-degree split point tip ensures quick and accurate drilling without the need for pre-punching, allowing for clean, precise holes. These drill bits enable higher cutting speeds and improved chip evacuation for faster, more efficient drilling, increasing productivity and reducing downtime. Suitable for various materials, including metal, plastic, wood, and composites, they are a versatile addition to any tool box.
