Zusammenfassung:In a chuck for use in a drilling device, such as a hammer drill, capable of performing rotary or rotary/percussion drilling, clamping jaws are provided to secure a tool in the drilling device. The clamping jaws each have a convex surface transverse to the chuck axis and with the surface directed inwardly toward the axis. The more radially inward portion of the convex surface has a V-shaped notch extending in the axial direction of the chuck. The notch forms a pair of spaced edges which grip the surface of the tool secured in the chuck so that the tool can be reliably rotated.
