The Diager Ultimax 646 drill bit has a solid head with 10 active cutting edges and a carbide tip, with 50% more carbide. The combination of concave and convex cutting edges, together with its demolition action, enables drilling into reinforced concrete. The 130° sharpening angle and aggressive centring tip make penetration easier, while the side cutting edges feature wear indicators.
Drilling force is concentrated along the axis for concentric drilling with precise dimensions. The drill bit reduces vibration and performs well when used with high-power rotary hammers.
