Diamond Rebar Cutter
Any time you need to drill a hole into concrete, and that hole has to be larger than 1″, you should probably be using a diamond rebar cutter core drill bit. These types of bits are specifically designed for drilling through extremely hard surfaces like stone or concrete, and they do a great job of penetrating through the material to create whatever size hole you need. The diamond rebar cutter core drill bits manufactured by B+BTec are equipped with super tough Proprietary Diamond Tip Matrix for the fastest possible penetration through whatever kind of hard material you need to have drilled.
