The Diager Ultimax 646 drill bit is suitable for drilling structural materials, including reinforced concrete. Its one-piece head has 10 active cutting edges and 50% more carbide, while the combination of concave and convex edges helps drill through reinforced concrete. The sharpened 130° tip facilitates penetration, while the aggressive centring point and wear indicator on the side edges support accurate, concentric drilling.
Drilling power is concentrated along the drill bit’s axis, reducing vibration. It performs best when used with high-power rotary hammers.
