Milling tool |
| 摘要 |
A tool for milling an item in a wellbore includes a number of cutting blades 210 which protrude from a surface 208 of the tool. The blades 210 are attached to the face 208 in a non-planar configuration which can be in the form of an L-shape (fig 7). A reinforcing member 216 may be present to prevent buckling of the blades 210. |
