This 115-piece cobalt drill bit set provides a comprehensive range of fractional, letter, and number sizes for drilling applications in tough materials. Cobalt steel (M35 grade) construction offers higher heat resistance and abrasion resistance compared to high-speed steel (HSS) bits, allowing for sustained performance in harder metals and abrasive materials without premature dulling.
These bits are used for drilling holes in stainless steel, cast iron, titanium, and other high-tensile strength alloys commonly found in fabrication shops, maintenance departments, and industrial settings. The cobalt alloy maintains its hardness at elevated temperatures, extending tool life during demanding operations.
