An apparatus is established which facilitates the cutting and removal of well casing on a single trip into the wellbore. The apparatus is run into the wellbore on the tubing string and provides a rotatable sleeve including grapples adapted to engage the casing, and to facilitate removal of the casing. The apparatus also includes cutting assemblies coupled to the mandrel, which may be rotated so as to cut the casing, thereby facilitating removal of the casing through use of the grapples.

Method and apparatus to cut and remove casing

This miling tool for underground work consists of a tool body which has a plurality of cutter blades. Each cutter blade has a negative axial rake and an essentially constant negative radial rake. In addition, each cutter arm has a close packing of cylindrical cutting grade tungsten carbide inserts set at a lead angle of about 0 to 10 degrees. The inserts are also preferably vertically offset on adjacent cutting blades.

Milling tool

A narrow diameter reaming tool can ream a hole which is up to ten times the diameter of the tool. The cutting arms of the tool are of a type such that if there is an excessive load on an arm, the arm will fracture rather than bend.
