The Diager Ultimax 646 drill bit with an SDS Max shank features a solid, 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, enables drilling through reinforced concrete. The 130° sharpening angle facilitates penetration, while the sharp centering tip helps ensure precise positioning.
The side cutting edges feature wear indicators, and drilling remains concentric with precise dimensions. Power is concentrated along the drill bit’s axis, while vibration is reduced. It delivers optimal performance when used with high-power rotary hammers.
