Drill with improved chip evacuation

A drill for metal cutting machining having a central rotation axis defining a longitudinal direction of the drill and around which the drill is rotatable, the drill comprising:

• an axially front end;
• an axially rear end;
• an envelope surface extending between the front end and the rear end;
• a shaft extending axially rearward from the front end;
• a shank extending axially forward from the rear end;
• at least one cutting insert releasably mounted at the front end;
• a first and a second chip flute in the envelope surface of the shaft;
• a coolant chamber inside the shank;
• and
• a first and second coolant channel extending from the front end of the coolant chamber and terminating at the front end of the drill, wherein the first coolant channel is associated with the first chip flute and the second coolant channel is associated with the second chip flute, wherein the coolant chamber includes a flow control element, which is movable between a neutral position, in which coolant flow is distributed substantially equally to the first and second coolant channels, and an active position, in which the flow control element directs the coolant flow at least mainly to one of said coolant channels, and that wherein the flow control element is arranged to move from said neutral position to said active position in response to a flow restriction in one of the first and second chip flutes, such that the coolant is directed at least mainly to the one coolant channel associated with the chip flute having a flow restriction.
