The Diager Ultimax 646 drill bit with a one-piece head has 10 active cutting edges and 50% more carbide. The 130° point angle and aggressive centering tip help it penetrate and drill accurately, producing concentric holes. The combination of concave and convex edges, together with its demolition action, allows it to drill through reinforced concrete.
The side edges feature a wear indicator, while drilling force is concentrated along the drill bit’s axis. It produces less vibration and performs best with high-power rotary hammers.
