Type D Cobalt Drill Bits

Engineered for high-performance drilling in the toughest materials, Type D cobalt drill bits are designed to withstand extreme heat and wear. Made from high-quality cobalt steel, these bits offer superior hardness and longevity compared to standard high-speed steel (HSS) drill bits. Their 135° split point tip ensures precise starts with minimal walking, while the parabolic flute design enhances chip evacuation, reducing heat buildup for smoother, faster drilling. Ideal for professionals and heavy-duty applications, these drill bits excel in drilling hardened steel, stainless steel, titanium, and other difficult alloys. Whether you're working in aerospace, automotive, or manufacturing, Type D cobalt drill bits deliver reliability and performance when it matters most.
