The Diager Ultimax 646 drill bit with an SDS Max shank has a one-piece head with 10 active cutting edges and 50% more carbide. The combination of concave and convex cutting edges, together with its demolition action, allows it to drill through reinforced concrete. The 130° sharpening angle facilitates penetration, while the sharp centering edge helps with initial positioning.
The side cutting edges feature wear indicators. The drill bit delivers concentric drilling with precise dimensions, concentrates drilling force along its axis, and reduces vibration. It performs best when used with high-power rotary hammers.
