Cutting tool with cutting head and cutting head driver

A cutting tool (2) for machining workpieces, comprising:

• a cutting head (10);
• and
• a cutting head driver (12) which can be connected to the cutting head (10) via a bayonet closure,
• wherein the cutting head (10) has a main body (14) from an end face (20) of which a protrusion section (16) that is axially undercut protrudes axially,
• wherein the cutting head driver (12) has a main body (24) from an end face (32) of which a protrusion section (26) that is axially undercut protrudes axially,
• wherein the protrusion section (16) of the cutting head (10) and the protrusion section (26) of the cutting head driver (12) can be connected to one another in a positive manner by rotating the cutting head (10) against a cutting direction of the cutting tool (2), and
• wherein the protrusion section (16) of the cutting head (10) and the protrusion section (26) of the cutting head driver (12) have torque-transmitting surfaces (18, 28), which are formed complementary to one another, are axially undercut, and abut against one another in a connected state, and
• wherein the protrusion section (16) of the cutting head (10) and the protrusion section (26) of the cutting head driver (12) are dimensioned so that the end face (20) of the protrusion section (16) of the cutting head (10) axially abuts against the end face (32) of the main body (24) of the cutting head driver (12) in the connected state.
