A displacement mechanism coupled to the cutting tool sets and adjusts a cutting position of the cutting tool relative to a tool axis. A sweeper coupled to the displacement mechanism deflects the displacement mechanism about the tool axis, and the cutting tool is deflected with the displacement mechanism. ## Claims ### Claim 1 A wellbore intervention tool for use in penetrating an obstruction in a wellbore, comprising: a cutting tool having at least one rotating cutter member for penetrating the obstruction; a displacement mechanism coupled to the cutting tool and operable to set and adjust a cutting position of the cutting tool relative to a tool axis; a sweeper coupled to the displacement mechanism and operable to deflect the displacement mechanism about the tool axis, wherein the cutting tool is deflected with the displacement mechanism; and wherein the rotating cutter member has a rotation axis at all times substantially perpendicular to the tool axis. ### Claim 2 (depends on 1) The wellbore intervention tool of claim 1, wherein the sweeper is configured to rotate the displacement mechanism through 360 degrees around the tool axis. ### Claim 3 (depends on 1) The wellbore intervention tool of claim 1, wherein the displacement mechanism is configured to set and adjust an offset angle between the cutting tool and the tool axis. ### Claim 4 (depends on 1) The wellbore intervention tool of claim 1, wherein the displacement mechanism is configured to set and adjust an offset distance between the cutting tool and the tool axis. ### Claim 5 (depends on 1) The wellbore intervention tool of claim 1, wherein the at least one rotating cutter member is a rotating cutting blade. ### Claim 6 (depends on 5) The wellbore intervention tool of claim 5, wherein the cutting tool comprises two counter-rotating cutting blades. ### Claim 7 (depends on 1) The wellbore intervention tool according to claim 1, wherein the at least one rotating cutter member is a drill bit. ### Claim 8 (depends on 1) The wellbore intervention of claim 1, further comprising a stroker for applying an axial force along the tool axis, wherein the stroker is coupled to the cutting tool such that the applied axial force exerts a downward pressure on the cutting tool. ### Claim 9 (depends on 1) The wellbore intervention tool of claim 1, further comprising a motor for rotating the at least one rotating cutter member. ### Claim 10 (depends on 1) The wellbore intervention of claim 1, further comprising an anchor for holding the wellbore intervention tool in place in the wellbore during penetration of the obstruction using the cutting tool. ### Claim 11 (depends on 1) The wellbore intervention tool of claim 1, further comprising a stabilizer for centralizing the wellbore intervention tool in the wellbore. ### Claim 12 (depends on 1) The wellbore intervention tool of claim 1, which is suspended on an end of a wireline or a coiled tubing having an electrical cable. ### Claim 13 (depends on 1) The wellbore intervention tool of claim 1, which is suspended conveyance, wherein the conveyance comprises an end of a fiber optic cable. ### Claim 14 A method of penetrating an obstruction in a wellbore, comprising: lowering a wellbore intervention tool into a wellbore, the wellbore intervention tool comprising a cutting tool having at least one rotating cutter member, a displacement mechanism coupled to the cutting tool, and a sweeper coupled to the displacement mechanism; positioning the least one rotating cutter member against the obstruction; rotating the at least one rotating cutter member while the at least one rotating cutter member is positioned against the obstruction wherein the rotating cutter member has a rotation axis at all times substantially perpendicular to a tool axis; and operating the sweeper to deflect the displacement mechanism about the tool axis during at least a portion of the rotating the at least one rotating cutter member. ### Claim 15 (depends on 14) The method of claim 14, further comprising operating the displacement mechanism to adjust the cutting tool to a select cutting position relative to the tool axis. ### Claim 16 (depends on 15) The method of claim 15, wherein operating the displacement mechanism comprises pivoting the cutting tool to a select offset angle relative to the tool axis. ### Claim 17 (depends on 15) The method of claim 15, wherein operating the displacement mechanism comprises linearly displacing the cutting tool to a select offset distance from the tool axis. ### Claim 18 (depends on 14) The method of claim 14, wherein operating the sweeper to deflect the displacement mechanism comprises operating the sweeper to rotate the displacement mechanism about the tool axis. ### Claim 19 (depends on 14) The method of claim 14, further comprising applying a downward or forward force to the cutting tool during at least a portion of rotating the at least one rotating cutter member. ### Claim 20 (depends on 14) The method of claim 14, further comprising anchoring the wellbore intervention tool in the wellbore during the rotating the at least one rotating cutter member.
