Makita SDS Drill bit is a wonderfully designed technically sound toolbox utility which is not only a perfect match for your drill, but it also saves the surface from being severed that it gets drilled into. Built with top-grade material, featuring a four-flute design as well as provisioned with hard alloy cutting edges, it digs right through the tough concrete like a melon, absolutely smooth. It also comes with a carbide-based tip which makes the drilling faster and really smooth.
