The hollow steel tube design allows the bit to grind only the outer perimeter of the hole, leaving a solid core plug that is extracted afterward. The segmented teeth feature high concentrations of industrial synthetic diamonds bonded in a soft cobalt-iron alloy matrix, allowing the bit to slice through embedded steel rebar without binding, utilizing sintered bonds similar to our premium <a href=\"/concrete-cutting-blades/\" style=\"color: var(--accent); text-decoration: underline; font-weight: 500;\">concrete cutting blades</a>.",

        "q": "How does a diamond core bit handle structural steel rebar?",
        "a": "The high concentration of diamonds in the segments grinds through the steel rebar. When the bit hits rebar, the operator must slightly reduce feed pressure and let the diamonds grind through the steel without forcing the drill."
