Abstract
A rotary slot cutting tool having a flat sided disc shaped body with a central bore, a plurality of apertures spaced about the periphery of the body each aperture having in it a cutting insert held in position by the shape of the aperture against radial movement, each aperture being shaped in such a manner that on the application of a force acting radially outwards on the circumference on the bore of the body, faces of the aperture are caused to spread apart to permit removal and replacement of the inserts in an axial direction. The invention further provides an insert for use in rotary and other slot cutting tools.
