The Diager ULTIMAX 646 concrete drill bit features a one-piece head with 10 active cutting edges and a carbide tip. The combination of concave and convex edges, together with its demolition action, enables it to drill through reinforced concrete. The 130° sharpening angle and aggressive centring tip make penetration easier.
The side edges have a wear indicator, while drilling remains concentric and precise. Drilling power is concentrated along the axis of the bit, with reduced vibration and high performance when used with powerful rotary hammers.
