Notes:<br />

• Cutting speeds shown in the left table are of the most<br />

outer diameter of the tool.<br />

• The values of the cutting speeds and feeds shown in the<br />

table are of under general cutting conditions. The values<br />

should be modified depending on the power and rigidity<br />

of the machine to be used, and work holding conditions.<br />

• When using the long shank type, the depth of cut, pick<br />

feed, cutting speed, and table feed should be reduced<br />

to 70 %-90 % of the values shown in the tables.<br />
