Cobalt Drill Bits

Cobalt Drill Bits

Milwaukee cobalt drill bits are built for drilling the hardest metals, including cast iron, mild steel, and stainless steel. The cobalt alloy runs through the entire bit, so it withstands the high heat of drilling tough materials and can be resharpened without losing its hardness, holding an edge where standard bits burn up or dull fast.

Great Lakes Power Tools carries Milwaukee cobalt bits in a range of diameters, available individually and in sets, for demanding metalwork and fabrication. Whether you're drilling stainless, hardened steel, or cast iron, there's a cobalt bit here to match the material.
