Downhole tool

A downhole tool for removing a restriction in a well tubular metal structure having a wall and an inner diameter, the restriction partly blocking the inner diameter, creating an opening defined at least partly by a rim section of the restriction, the downhole tool having a tool axis and comprising:

• a tool body having a first part and a second part,
• an electrical motor arranged in the first part and configured to rotate a rotatable shaft, and
• a core bit arranged in the second part and having a first end connected with the rotatable shaft and a second end having a cutting edge,
• wherein the second part of the downhole tool further comprises:
• a locator configured to locate the rim section, and
• a collector,
• wherein the locator and the collector are configured to rotate with the core bit until the locator locates the rim section and a threshold value is reached, and wherein the locator and the collector are configured to be disconnected from the rotation of the core bit when the threshold value is reached.
