•After grinding first relief face, grind second relief face.

•As shown in fig.2 of the previous section, keep rotation angle of the drill (work head) at 20°.

•As shown in fig.4, set inclination angle of the drill (work head) at 23°~ 27°.

If inclination angle of the drill (work head) cannot be increased to 23°~27°, get the wheel inclined 15°as shown in fig.5.

•Grind second relief face, and the ridgeline of first and second relief face will appear.

•As shown in fig.6, it is ideal that the ridgeline is parallel to the line connecting the corner of center cutting edge and the shoulder of outer peripheral edge. Adjust the drill phase while grinding.

•Grind until ridgelines on both sides become one line. By this, the center point at the top will be formed. As such, please be careful not to grind too much or too little.
