All dimensions are in inches. All cutters are high-speed steel and are form relieved. For keyway dimensions see page 894 . For cutter selection see page 2266 . Tolerances: On outside diameter, + 1 ⁄ 16 , - 1 ⁄ 4 -inch hole diameter, +0.0010 inch. To select the cutter number for bevel gears with the axis at any angle, double the back cone radius and multiply the result by the diametral pitch. This procedure gives the number of equivalent spur gear teeth and is the basis for selecting the cutter number from the table on page 2229 . 16 inch; on hole diameter, through 1-inch hole diameter, +0.00075 inch, for 1 1 ⁄
