Suitable for a variety of indexable turning tools that require more accurate calculation and measurement of tool length dimensions, tool tip height dimensions or tool tip to side base dimensions.
When calculating and measuring the above dimensions of the turning tool, the position of the reference point K shall be as specified in Figures 1 to 4.
1. Dimensions L, h1 and f are as specified in Figure 1.

2. The position of the reference point K is as specified in Figures 2 to 4 for different lead angles kr and feed directions.
1) For an outer circle or a contour turning tool whose main angle kr is less than or equal to 90°, the position of the reference point K is as shown in Fig. 2.
