- When chips stay in the cutting zone during slotting or pocketing, use air blast to remove - Tool overhang length must be as short as possible to avoid chatter. When the tool overhang

88°Cautionary points in use
90The use of a standard or long shankTool geometry on programming

When using a long shank, please lower the cutting conditions (Vc, fz, ap) to 70% When programming for CAM, the tool should be considered as a radius cutter. of the maximum conditions for the standard shank. Usually, the corner radius should be set as R = 1.5 mm. If a larger radius is used, overcutting will occur. The following table shows the amount left uncut (t1) and Others overcut (t2).
