Abstract
The present invention relates to a downhole tubing intervention tool for submerging into a casing in a wellbore and for selectively removing material from within the casing, the tool extending in a longitudinal direction, comprising a tool housing having a first housing part and a second housing part, a rotation unit, such as an electrical motor, arranged in the second housing part, and a rotatable shaft rotated by the rotation unit for rotating at least a first segment of abrasive material being connected with the first housing part and forming an abrasive edge, wherein the first segment is movable between a retracted position and a projected position in relation to the first housing part of the tool housing.

A downhole tubing intervention tool for submerging into a casing in a wellbore and for selectively removing material from within the casing, the tool extending in a longitudinal direction, comprising:
- a tool housing having a first housing part and a second housing part,
- a rotation unit, arranged in the second housing part, and
- a rotatable shaft rotated by the rotation unit for rotating at least a first segment of abrasive material being connected with the first housing part and where the abrasive material comprises abrasive grains and a binder forming an abrasive edge, where the abrasive material is configured to expose new abrasive grains as the abrasive material wears during use,
- wherein the first segment is movable between a retracted position and a projected position in relation to the first housing part of the tool housing,
- wherein the first segment tapers in a radial direction away from the longitudinal direction from a base part into a terminal end, forming a radial tip.
