Abstract:
A boring head comprising:a tool body and at least one bit carrier affixed to the tool body in a detachable manner, wherein the bit carrier is slidably mounted for radial adjustment on a clamp plate of the tool body, with clamping means for clamping the bit carrier against said clamp plate and with a catch plate surface arranged on the tool body which collaborates with a corresponding catch plate of the bit carrier for transmission of torque, wherein the tool body at a distance from its catch plate surface has an angled outer wedge surface against which an angled wedge surface of the bit carrier is clamped and wherein the wedge surface of the tool body exerts a radial clamping force on the bit carrier which clamps the catch plate of the bit carrier radially against the catch plate of the tool body, and wherein said bit carrier carries a bit and transmits torque as a cutting force in a direction tangential to an arc circumscribed about the axis of rotation by the bit.
