A boring bar, such as for internal turning, includes a front pocket that is defined by a shelf-like surface and a ramp surface, an insert seat that is countersunk in the shelf surface and disposed asymmetrically in relation to a center axis, a chip flute that is countersunk in the outside of the bar is disposed on the same side of the center axis as the insert seat, and an internal channel that supplies a fluid to the front part of the bar. The fluid channel ends in an outlet mouth disposed on the side of the bar that is opposite the insert seat in order to guide a flow of the fluid past the insert seat toward the front opening of the chip flute.
