In this paper, the flank wear and the surface roughness of machined surface are investigated by high speed milling of hardened steel for a small size ball end mill. And it is investigated that the influence of a tool life on the inclination angle of workpiece and the minimum qualify lubrication (MQL) method. In case of the carbide tool, it is shown that the long tool life and the small surface roughness are obtained by the conditions of down milling and the MQL method to end point of cutting. In case of the connected tool with carbide and alloy steel, it is shown that the long tool life is obtained only in the conditions of step up pick feed, and the surface roughness becomes large.
