A section mill for milling a wellbore tubular comprising:
- (a) a carrier pipe string, said carrier pipe string having a carrier pipe string central fluid bore;
- (b) a top sub, said top sub having an upper end, a lower end, and a top sub central fluid bore, said upper end of said top sub attached to said carrier pipe string whereby said top sub central fluid bore is in fluid communication with said carrier pipe string central fluid bore;
- (c) a longitudinally extending tubular mill body, said tubular mill body having an upper end, a lower end, and a mill body central fluid bore, said upper end of said tubular mill body attached to said lower end of said top sub, whereby said top sub central fluid bore is in fluid communication with said mill body central fluid bore;
- (d) a translatable longitudinally extending tubular piston mandrel positioned within said mill body central fluid bore, said tubular piston mandrel having an upper end, a lower end, and a piston mandrel central fluid bore in fluid communication with said mill body central fluid bore;
- (e) an upper piston attached to said elongated tubular piston mandrel, said upper piston positioned within an upper piston chamber in said tubular mill body, said upper piston chamber in fluid communication within said piston mandrel central fluid bore;
- (f) a lower piston attached to said elongated tubular piston mandrel, said lower piston positioned within a lower piston chamber in said tubular mill body, said lower piston chamber in fluid communication within said piston mandrel central fluid bore;
- (g) a first plunger attached to said lower end of said tubular piston mandrel;
- (h) a first longitudinally extending cutter shoe having at least one cutter surface, said first cutter shoe having an upper end and a lower end,
- (i) a first yoke link pivotally attaching said upper end of said first cutter shoe to said first plunger;
- (j) a first support link pivotally attaching said first cutter shoe to said tubular mill body;
- (k) a second plunger attached to said lower end of said tubular piston mandrel;
- (l) a second longitudinally extending cutter shoe having at least one cutter surface, said second cutter shoe having an upper end and a lower end,
- (m) a second yoke link pivotally attaching said upper end of said second cutter shoe to said second plunger;
- (n) a second support link pivotally attaching said second cutter shoe to said tubular mill body;
- and
- (o) wherein said first and said second yoke links are comprised of pairs of yoke link segments and wherein said first and said second cutter shoe support links are comprised of pairs of support link segments.
