Abstract
A device for abrasive machining, comprising a substantially cup shaped to rough rotatable around an axis and having an inner chamber and a disk-shaped to working element at its one axial end; and immovable holder attachable to a machine to and surrounding at least a portion of said working element at an opposite axial end at a distance therebetween so as to form a passage for passing a cooling liquid; and a helical guiding means provided in said passage so that during rotation of said tool inside said holder the cooling liquid is supplied through the substantially helical guide into said inner chamber of said tool toward said working element.
