Abstract: A cutting insert for chip cutting machining, preferably for plane milling operations, has a generally square geometry and comprises a chip face and a number of clearance faces. A portion of the chip face is beveled and extends along a cutting edge from one cutting corner toward an adjacent cutting corner. The beveled portion is angularly oriented such that the insert obtains a more negative cutting geometry near the cutting corner than at a distance therefrom in order to achieve increased strength of the insert.

Abstract: An indexable cutting insert (10) for a tool (18) adapted to cut internal right-angled corners in a work piece (19). The insert (10) has a square configuration and comprises a top major surface (11), a bottom major surface (12) and connecting side surfaces (13). The lines of junction between the top major surface and the side surfaces define the main cutting edges (14) and the minor cutting edges (15). The main cutting edges (14) transite into the second cutting edges (15) in the corners of the insert. Each second cutting edge (15D) projects from the square basical shape so that it will lift the inactive main cutting edge (14A) from the machined surface under the insert.

Abstract: This invention relates to a saw guide bar comprising two side plates and an intermediate layer. Each side plate comprises a layer of reinforced plastic material and a layer of metal.

Abstract: A saw guide bar comprising a main part and a nose part detachably fastened to the main part, the joints between the nose part and the main part being displaced relative to each other in the direction of chain travel.
