Abstract: A cutting tool having an elongate cutting head provided with a plurality of teeth and flutes in which a plurality of cooling grooves are recessed at a land region of each tooth between a cutting edge and a trailing edge. The grooves at the land do not extend to and are physically separated from the cutting edge to provide a tool optimized for cutting via radially consistent cutting edges and the promotion of heat exchange and dissipation from the rearward side/region of the teeth.

Abstract: An end mill has a shank section and a cutting section connected thereto. The cutting section includes a core supporting at least two spaced apart teeth that have a cutting edge extending in the axial direction with respect to the axis of rotation of the end mill. Each cutting edge has a flute associated therewith and each flute has, for each cross-section of the end mill perpendicular to the axis of rotation thereof, a bottom point on the core at a shortest distance to the axis of rotation. At least two flutes have a shortest distance that varies differently with the distance to a cutting end of the end mill.
