Tool for fine machining of surfaces

A tool for fine machining of surfaces, the tool comprising:

• a working medium carrier comprising a top face and a bottom face, wherein the bottom face is an attachment side;
• a set of individual exchangeable strip-shaped lamella holders, each comprising one or more lamellas in individual or bundled arrangement, wherein the lamellas each are oriented away from the attachment side of the working medium carrier and form in a downward direction remote from the attachment side a common working plane;
• wherein the lamella holders on a side facing the attachment side are provided with hooking elements and wherein the attachment side of the working medium carrier is provided with hooking receptacles that are complementary to the hooking elements;
• wherein the hooking elements are configured to be directly inserted into the hooking receptacles in a direction perpendicular to a downward face of the attachment side;
• wherein the hooking elements are configured to elastically yield to move into a mutual locked connection at the hooking receptacles, or the hooking receptacles are configured to elastically yield to move into a mutual locked connection at the hooking elements, wherein the lamella holders are locked at the working medium carrier solely by said mutual locked connection.

• wherein the lamella holders on a side facing the attachment side are provided with first hooking members and wherein the attachment side of the working medium carrier is provided with second hooking members complementary to the first hooking members;
• wherein the first and second hooking members are configured to be joined to each other in a direction perpendicular to the attachment side;
• wherein the first hooking members or the second hooking members are configured to yield for moving into a mutual locked connection;
• wherein the first hooking members are yielding projections provided with undercut faces and the second hooking members are openings provided in the attachment side of the working medium carrier, wherein the yielding projections are configured to be inserted with elastic deformation into the openings and the undercut faces of the projections lock at the openings after having passed through the openings.
