Sandvik Coromant’s  (Fair Lawn, NJ) CoroBore 825 offers superb performance in the finishing of holes with tight tolerances and surface finish requirements. This fine boring tool offers highly stable and reliable performance when finishing components.

The tool features a coupling design that integrates an elliptical interface that absorbs tangential and radial forces. To achieve maximum flexibility, the CoroBore 825 accommodates three cartridge sizes, each with its own slide extension. The slide extensions are placed between the cartridge and cross slide to allow for back boring and to extend the maximum diameter when boring forwards. All cartridges use triangular inserts and (-2)-degree lead angles.
