A cutter insert tool holder effects bidirectional linear cuts on a work surface. The tool holder includes two elongated slots sized to accommodate first and second cutting insert holders. The tool holder includes an actuator arm that is placed in a first pivoting position by contacting the work surface while the tool holder is displaced along the work surface in a first direction, the pivoting actuator arm causes an actuator cam to contact and engage the second cutting insert holder so that it is withdrawn while the first cutting insert forms a cut in the work surface. When the tool holder is displaced along the work surface in a second direction opposite the first direction, the pivoting actuator arm causes the actuator cam to contact and engage the first cutting insert holder so that it is withdrawn while the second cutting insert forms a cut in the work surface.

A method for deburring an internally toothed workpiece includes providing a workpiece and a deburring tool. The workpiece has an inner toothing produced by hob peeling, with first and second tooth flanks. The deburring tool has a first cutting plate and a second cutting plate, diametrically opposed to the first cutting plate. The method includes rotating the workpiece in a first rotating direction and deburring the first tooth flanks with the first cutting plate while the deburring tool is not rotating. The method also includes shifting the deburring tool relative to the workpiece such that the first cutting plate and the second cutting plate do not contact the workpiece, rotating the workpiece in a second rotating direction, opposite the first rotating direction, further shifting the deburring tool relative to the workpiece, and deburring the second tooth flanks with the second cutting plate while the deburring tool is not rotating.

A method for roughening a cylinder bore wall to be coated of a component, at least one groove, running around the central longitudinal axis, and at least one associated groove web, are generated such that the at least one groove web, in a radial direction directed toward the central longitudinal axis, forms first undercuts for a coating which is to be applied. Axial grooves running in the cylinder bore wall transversely to the at least one groove are generated such that the at least one groove web, in a peripheral direction about the central longitudinal axis, forms respective second undercuts for the coating which is to be applied. An adhesion of the coating which is to be applied, in the peripheral direction, is improved, so that stress cracks or detachments owing to a different thermal expansion of the component and of the coating which is to be applied are avoided.

A tool head includes a first tool and a second tool disposed circumferentially on the tool head where the tool head has a rotation axis. The first tool of the tool head is an adjustable tool that is radially movable such that a radial position, relative to the second tool of the tool head, is settable.

A drill chuck having a chuck body, having a clamping sleeve with a conical basic shape that can rotate about the chuck axis of the chuck body, by the rotation of which clamping sleeve a plurality of clamping jaws can be moved relative to the clamping body. The clamping sleeve is made in two parts, having a conical, metallic outer sleeve, having a conical, inner sleeve made of plastic, wherein the outer sleeve has a cylindrical subsection on its inner circumference for radial centering of the outer sleeve on the inner sleeve. A clamping sleeve and a method for producing knurling on the clamping sleeve are also provided.
