The Diager ULTIMAX 646 drill bit with an SDS Max shank is designed for drilling concrete, including reinforced concrete. Its one-piece head has 10 active cutting edges and 50% more carbide, while the combination of concave and convex edges helps cut through concrete.
The 130° sharpening angle facilitates penetration, and the aggressive centering point helps ensure precise drilling starts. The side edges feature a wear indicator, while drilling remains concentric and precise. Power is concentrated along the drill bit’s axis, and vibration is reduced.
