Tool for crushing coke

A tool for crushing coke, comprising:

• a housing (2) that, in an operating state, is fastened to a drill rod, and in which
• at least one cutting nozzle (10) for cutting and a drilling nozzle (9) for drilling coke by a water jet, and
• a control for supplying water flowing through the housing (2) under pressure for drilling or cutting is arranged,
• wherein a control for switching the tool (1) from a drilling mode to a cutting mode and vice versa comprises a control device (7) that is rotatable about a longitudinal axis (A) of the housing (2) to switch the tool (1),
• wherein the drilling or cutting mode is set depending on angular position of the control device (7),
• wherein
• at least one position element (38, 39) is arranged on the control device (7) that displays the angular position of the control device (7) in the drilling and/or cutting mode of the tool (1) through a window (18) in the housing (2), wherein two position elements (38, 39) are arranged on the control device (7) that are different from each other and offset from each other at an angle, of which a first position element (38) is assigned to the display of the angular position of the control device (7) in the drilling mode of the tool (1), and a second position element (39) is assigned to the display of the angular position of the control device (7) in the cutting mode (1).
