ABSTRACT:
A helix drill for metal chip removing machining includes a shank which defines a longitudinal rotary axis and has front and rear ends. The front end carries two cutting edges. Two chip flutes are formed in an outer periphery of the shank and extend helically rearwardly from respective cutting edges for conducting chips. Two coolant channels extend within the shank for conducting cooling fluid. A major part of the length of each cooling channel is straight and oriented parallel to the axis. A total helical twist of each of the chip flutes along the length of the shank is about 30.degree..
