A new, innovative tool useful in fluidly coupling a lateral pipeline to a reinstated pipeline containing a continuous liner is provided. The pipeline reinstatement tool includes a flexible shaft that is coupled to a cutting head at a first end and a coupling assembly at a second end. The cutting head includes a hollow cylindrical member having cutting teeth that project longitudinally from the first end of the hollow cylindrical member. The tool includes a first compressible tensioner portion disposed about the flexible shaft proximate cutting head, a second compressible tensioner portion disposed about the flexible shaft proximate the coupling assembly, and a flexible sleeve portion disposed about the flexible shaft between the first compressible tensioner portion and the second compressible tensioner portion.

A cylindrical calibration head for the drilling of a shaft, includes three flutes arranged evenly around the circumference so that they are spaced one from the next by an angle of 120° with respect to a rotation with respect to the axis of the calibration head, the flutes allowing for the removal of chips and the passage of lubricant during drilling, each of the flutes including a machining insert of which the position in the flute can be adjusted using an adjusting cartridge.

A self-adjusting tool for chamfering an end of a cylinder includes a plurality of legs. A distal segment of each of the legs extends in a forward direction of the tool and is placeable about the end of the cylinder. A central body has a rotatable shaft and a mechanism that is operable by rotation of the shaft about a shaft axis. The mechanism is operable to retract the legs inward in tandem toward the cylinder and to rotate the legs about the shaft axis when further retraction of the legs is blocked by contact with the cylinder. One or a plurality of chamfering blades are each attached to one of the legs. A cutting edge of each blade is oriented diagonally forward and inward.
