Precautions
* Recommended cutting direction：Down cut
* The values for recommended cutting conditions are calculated by Toyo, and may need to be slightly modified to match the material, condition of the workpiece, the processing machine and so on.
* When cutting into the workpiece, divide the work over several times, according to the material, condition of the workpiece, the processing machine and so on.
*If you want to increase the roughness, it is not a problem to reduce the cutting speed than the above conditions. This may shorten the tool life.
