Cautionary points in use Because the ESD5000 type endmills are not provided with a center cutting edge the cutter cannot be used for plunging. When chips tend to stay in cutting area use an air blast to remove them. And especially when pocketing a deep cavity use of air blast through the air hole integrated in the shank is effective. When drilling a hole use the helical interpolation function (G02 G03) of the CNC controller. The max. and min. machinable diameter are shown in the table below. Cat.

When indexing or changing the insert after removing all foreign matter in the insert pocket with use of an air blast carefully mount the insert not so as to leave a gap between the insert and pocket face.
