The Diager Ultimax 646 drill bit features a solid, one-piece head with 10 active cutting edges and 50% more carbide. The combination of concave and convex edges, together with its demolition action, enables drilling through reinforced concrete. The 130° sharpening angle facilitates penetration, while the sharp centering tip helps ensure accurate drilling starts.
The side edges feature a wear indicator, and drilling remains concentric with precise dimensions. Force is concentrated along the drill bit’s axis, while its reduced vibration and performance make it suitable for use with powerful rotary hammers.
