Fig. 2. A Typical Single-Point Carbide-Tipped Cutting Tool The tip of the brazed carbide blank overhangs the shank of the tool by either 1 ⁄ 32 or 1 ⁄ 16 inch, depending on the size of the tool. For tools in Table 5, Table 6, Table 7, Table 8, Table 11 and Table 12, the maximum overhang is 1 ⁄ 32 inch for shank sizes 4, 5, 6, 7, 8, 10, 12 and 44; for other shank sizes in these tables, the maximum overhang is 1 ⁄ 16 inch. In Table 9 and Table 10, all tools have maximum overhang of 1 ⁄ 32 inch. Single-point Tool Nose Radii: The tool nose radii recommended in the American National Standard are as follows: For square-shank tools up to and including 3 ⁄ 8 -inch
