ABSTRACT:
The present invention relates to a tool as well as a blank for manufacturing of the tool. The tool is made of solid cemented carbide and includes a shank for mounting in a rotatable spindle and chip flutes. Lines of intersection between the chip flutes and clearance surfaces form cutting edges at a cutting end of the tool. The flush channels extend through the entire tool in order to transfer flushing medium to the cutting end of the tool. The flush channels have varying pitch.
