Notes:<br />
• As a rule, dry cutting (or air-blowing) is generally recommended.<br />
• If a cutting fluid is used, the cutting speed should be set to the<br />
lower side of the values shown in the above table.<br />
• When being used in square shoulder milling, climb milling is<br />
recommended.<br />
• In square shoulder milling of stainless steel, when chips tend to be<br />
recut during cutting, change to up-milling mode.<br />
• When wet machining mild steels, carbon steels and alloy steels, use<br />
T3130 at lower cutting conditions.<br />
