Title: MILLING TOOL WITH COOLANT FLOW GROOVES
Abstract:
A milling tool (10) having an elongate cutting head (12) provided with a plurality of teeth (20) and flutes (14) in which a plurality of cooling grooves (22) are recessed at a land region of each tooth (20) between a cutting edge (15) and a trailing edge (16). Advantageously, the grooves (22) at the land (17) do not extend to and are physically separated from the cutting edge (15) to provide a tool optimised for cutting via radially consistent cutting edges (15) and the promotion of heat exchange and dissipation from the rearward side/region of the teeth (20).
