Downhole tool

A downhole cutting tool for submerging into a casing, the tool comprising:

• a tool housing having an outer surface, a first end and a second end, and a longitudinal extension having a longitudinal axis, and the tool housing having a first housing part and a second housing part, where the first housing part is arranged to rotate or move along the longitudinal axis relative to the second housing part,
• an electric motor and a pump, where the electric motor is configured to rotate the first housing part,
• at least one cutting arm connected with the second housing part, where in a first operational position the at least one cutting arm is in a first position relative to the tool housing, and in a second operational position the at least one cutting arm is in a second position relative to the tool housing, where in the first operational position the at least one cutting arm is in a different position relative to the outer surface, the first end or the second end than in the second operational position,
• a hydraulic actuator configured to move the at least one cutting arm from the first operational position to the second operational position and vice versa, and
• a resistive sensor having a variable resistor, where a first part of the resistive sensor is coupled to a moveable element of the tool that is in mechanical communication with the at least cutting arm and configured to allow movement of the at least one cutting arm, and a second part of the resistive sensor is coupled to the tool housing, and where the movement of the moveable element is configured to change the resistance of the variable resistor to register the position of the at least one cutting arm relative to the tool housing.
