The Diager Ultimax 646 drill bit is designed for drilling into concrete and features a one-piece head with 10 active cutting edges and 50% more carbide. The combination of concave and convex edges, together with its demolition action, allows it to cut through concrete reinforcement. The centering tip and 130° sharpening angle aid penetration and ensure precise, concentric drilling.
The side edges feature a wear indicator, while drilling force is concentrated along the drill bit’s axis. Its design reduces vibration and supports use with powerful rotary hammers.
