and the tubular and provide a retention support for the lubricant 18 examples of isolation materials include a gel a colloidal suspension a polysaccharide gum xanthan gum and guar gum one characteristic of suitable isolation material may include materials that are thixotropic i e they may change their properties when external stresses are supplied to them as such the isolation material should have a certain amount of inherent shear strength high viscosity and surface tension in order retain its form within the annular space and provide a retaining force to maintain the lubricant in a selected area thus as shown in fig1 the presence of the isolating material on opposite sides of the lubricant helps retain the lubricant within the cutting zone an alternative embodiment of a cutting tool 10 a is provided in side partial cross sectional area in fig2 in this embodiment a single set of nozzles 16 is provided on the body 11 a optionally in this situation the isolation material nozzles 16 could be disposed lower than the lubrication nozzles 20 yet another embodiment of a cutting tool 10 b for use in cutting tubulars with added lubrication is provided in side view in fig3 in this embodiment the cutting member 12 a is a straight blade affixed to a portion of the body 11 b although in this embodiment a single set of nozzles 16 is shown for disposing isolation material.
