Cutting Conditions
This table is a guideline for selecting cutting parameters. Adjust them as needed according to the machine and workpiece conditions. Generally, wet cutting provides a better surface finish. Lower the feed if secondary burrs appear.

Keep the tool projection length as short as possible. Stop using the tool if it receives strong impact such as collision. The tool becomes hot during cutting. There is a risk of burn if touched immediately after use. Use protective equipment such as safety enclosures and glasses against scattering chips or tool breakage caused by accidents.
