An anchoring system for use with a downhole tool includes a body with anchor members mounted on the body that pivot radially outward from the body and into engagement with an inner surface of a tubular. Curved slots are provided along a portion of the members and a sliding block has a protrusion that projects into the slots. The slots are curved so that when the block is urged axially within the body, the interaction between the slots and protrusions pivots the members radially outward. A piston is urged through the body to drive the block. Optionally, an elongate helical gear may cooperate with grooves formed in an edge of the members so that rotating the gear pivots the members radially outward.

Downhole clamping mechanism

The tubular cutting tool for severing downhole tubulars, the tool having a drive system, a pivoting system, a cutting head, a cutting member, and a lubricant delivery system. Cutting may be accomplished by rotatingly actuating the cutting head with an associated motor and extending the cutting member away from the cutting head. The lubricant delivery system lubricates the respective contacting surfaces of the cutting member and the tubular and is actuated when the cutting member extends from the cutting head.
