1. A blade holder comprisinga blade seat comprising a holder connection surface and longitudinal jaws disposed on opposing sides of the holder connection surface, and a holder passageway configured for conveyance of coolant and comprising a coolant path extending therethrough from a holder inlet aperture to a holder outlet aperture formed at the holder connection surface;
- the holder passageway comprises a preceding portion and a deceleration chamber closer than the preceding portion to the holder outlet aperture, and a transition region at which the preceding portion transforms into the deceleration chamber;
in the preceding portion at the transition region, the holder passageway has a preceding portion cross-sectional area extending perpendicular to the coolant path,in the deceleration chamber at the transition region, the holder passageway has a deceleration chamber cross-sectional area extending perpendicular to the coolant path, wherein;
the deceleration chamber comprises a barrier surface facing the coolant path of the preceding portion at the transition region;
the holder connection surface is formed with a sealing element recess that surrounds the holder outlet aperture; and
a sealing element is mounted in the sealing element recess.
