Abstract

PURPOSE:To obtain a regrindable drilling tool with long life, by applying a coating of sintered carbides 0.1-20mu thick partially or fully to the peripheral margin of a twist drill with its point angle 100-130 deg. and two stripes of twist flutes of 20-45 deg.. CONSTITUTION:Sintered carbides of TiC, TiCN, TiCNO and/or Al2O3 are used as a coating, For the method of coating, though the methods CVD and PVD, which have been popularized, are conventionally economical, a similar effect can be also obtained from the methods of flame spraying, ion inplantation, diffusion treatment, etc. A full resistance for wear can not be obtained from the layer of its coating in thickness not more than 0.1mu and a generation of exfoliation is caused from that in thickness not less than 20mu and not preferable.
