摘要

The tool (1) for the removal of flash, especially at the opening of two or more drillings within a component, has a rotating lance (2) with an outflow channel (5) for a high pressure fluid at its end section (4). The outflow channel is generally parallel to the rotary axis (3) of the lance, offset from it in a radial direction. The transit (21) between the fluid feed (6) and outflow channels is rounded or chamfered, to prevent eddies and a pressure drop in the fluid.
