  • Deep hole drill comprising a coating
    Patent number: 9339875
    Abstract: The invention relates to a deep-hole drill, comprising a first coating extending over the effective length of the guide section and a second coating that is applied to the tip of the drill in the cutting region, the region of which extends over an axial length that, at a maximum, corresponds to double the nominal diameter of the drill. In such a way, when the bore tip is worn by use, said tip can be recoated after sharpening without the nominal diameter of the drill tip substantially increasing, in particular even after being sharpened several times.
