Abstract:
1. A stripping device for use with a cutting tool with a cutting element for machining a workpiece, the cutting element being movable along a longitudinal axis, the stripping device comprising: at least one fastening piece for fastening the stripping device to the cutting tool; a spring-elastic element which is arranged outside the workpiece contact region and around the cutting element; a stripping element which surrounds the cutting element, wherein the stripping element has a non-circular cross-section and a front surface, the front surface being defined by a beveled portion having a bevel angle, the beveled portion coming into contact with the workpiece along a contact plane, and wherein the contact plane defines a non-zero angle with respect to a plane perpendicular to the longitudinal axis at least when the cutting element passes through the workpiece, and wherein the beveled portion comprises an inner periphery which defines a passage opening through which the cutting element passes, and wherein the bevel angle surrounds the passage opening and extends from one side of the front surface, over the passage opening, and to the other side of the front surface; and a guide element having an outer surface with a circular cross-section and having an inner surface defining a hole with a non-circular cross-section corresponding in shape with the non-circular cross-section of the stripping element, the entire surface of the hole being formed by a single homogenous piece of material, wherein the guide element is configured to guide the stripping element and independently prevent the stripping element from rotating.
