The present invention relates to a machining tool (30) with a shaft (8) extending along a tool axis (4), a cutting head (6) axially adjoining the shaft (8) and an internal cooling lubricant channel system formed from a centrally running inlet channel (12), which leads from an inlet opening (10) at the shaft end in the direction of the cutting head (6) all the way to a branch point (14), which lies at a defined axial distance from the inlet opening (10), at least one outlet channel (18) running in a decentralized manner, which leads to an outlet opening (20) on the cutting head front side, and a branch channel (16) running in a straight line, which branches off from the inlet channel (12) at the branch point (14) and which leads to the outlet channel (18) at a defined angle. A cross sectional surface of the at least one branch channel (16), which is projected along the at least one branch channel (16) in the direction of the shaft end, lies completely within the inlet opening (10).

A machining tool with a shaft extending along a tool axis, a cutting head attached to the shaft at a joining point and an internal cooling lubricant channel system formed from a centrally running inlet channel, which leads via a shaft-side channel section from an inlet opening at the shaft end all the way to a connection opening at the joining point and via a cutting head-side channel section from the connection opening all the way to a branch point in the cutting head, at least one outlet channel running in a decentralized manner, which leads to an outlet opening on the cutting head front side, and a branch channel running in a straight line, which branches off from the shaft-side inlet channel at the branch point and leads to the outlet channel at a defined angle, wherein:
