Abstract: The present invention relates to a method for grinding, with a grinding machine (100), a rotary cutting tool (20) comprising a cutting part (22) and a shank (26). The grinding machine (100) comprises a headstock (102) with a spindle (104) arranged to receive one end portion of a workpiece (10) to rotate said workpiece about a rotation axis (X), and a guiding support (50) to support a portion of the workpiece (10) during grinding of the cutting part. The guiding support (50) comprises a guiding surface (52) having a cross-section, within a plane orthogonal to said rotation axis, of an incomplete annulus. The method comprises the following steps: i) mounting said one end portion of the workpiece (10) into the spindle (104) and rotating said workpiece about the rotation axis (X); ii) performing sharpening operations, on a portion of the workpiece intended to become to the cutting part (22) of the final cutting tool with grinding wheels (W2, W3, W4) to obtain a sharpen segment, and iii) grinding the sharpen segment down to a final diameter including the back taper with another wheel (W5) to obtain the cutting part (22) of the cutting tool (20). The portion of the workpiece intended to become to the cutting part (22) of the final cutting tool is supported by the guiding support (50) during steps ii) and iii).
