The present invention provides a pipe cutter apparatus that includes a housing having a base and lid. The lid is moveable between a storage position and an operative position. A motor is retained within the housing and has a shaft operatively connected thereto and rotated thereby. A cutting wheel extends radially from the shaft and is rotated with the shaft. A pipe conveyor is also retained within the housing, adjacent the cutting wheel. The pipe conveyor may be operated to urge a pipe placed therein into engagement with the cutting wheel. The pipe conveyor is preferably adjustable to receive pipes of various diameters. Notably, when the lid is in the operative position, a work area is provided for cutting a pipe or similar work piece. When the lid is in the storage position, a carrying case is provided such that the pipe cutter apparatus is readily portable. A cleaning brush also extends from the shaft that is rotated by the motor. Various embodiments for the cutting wheel, conveyor, and cleaning brush elements are provided.

The apparatus of claim 1 wherein the extendable element is selectively extendable and selectively retractable and the at least one extendable gripper element is selectively extendable and selectively retractable. 7. The apparatus of claim 1 further comprising a plurality of selectively extendable stabilizers mounted on the work string for stabilizing the work string while the work string is translating through the borehole. 8. The apparatus of claim 7 wherein the at least one gripper element is integral to at least one of the plurality of stabilizers. 9. The apparatus of claim 1 further comprising a first selectively expandable packer device mounted on the work string and a second selectively expandable packer device mounted on the work string and spaced apart from the first selectively expandable packer device, the first and second expendable packer devices being expandable to contact the borehole wall in a sealing relationship to divide an annular space surrounding the work string into an upper annulus, an intermediate annulus and a lower annulus, wherein the at least one extendable element is located at the intermediate annulus. 10. The apparatus recited in claim 1, wherein said test port is located in said extendable element. 11. The apparatus of claim 1, wherein the port is a plurality of ports. 12. A method for testing an underground formation comprising: a) disposing a work string in a well borehole; b) isolating a portion of the borehole wall by extending at least one independently extendable element from the work string to sealing engagement with the wall of the borehole at the formation; c) independently extending at least one gripper element into forceful engagement with the borehole wall axially spaced apart from a port, the port being exposed to the isolated portion of the borehole wall, wherein the at least one gripper element when extended anchors the work string radially, axially and circumferentially while the borehole wall is engaged by the at least one extendable element; and d) testing at least one characteristic of the formation at the isolated portion of the borehole well with a test device. 13. The method of claim 12, wherein testing the at least one characteristic further comprises: i) flowing formation fluid through the port from the isolated portion of the borehole wall with a fluid control device; and ii) sensing at least one characteristic of the fluid with a sensor. 14. The method of claim 13, further comprising collecting a sample of formation fluid by flowing fluid from the port to at least one sample chamber. 15. The method of claim 12, wherein disposing a work string in a borehole comprises a work string selected from the group consisting of (i) a drill string; and (ii) a wireline. 16. The method of claim 12, wherein extending at least one gripper element is extending at least two gripper elements. 17. The method of claim 12, further comprising: i) translating the work string through the borehole; and ii) stabilizing the work string while translating the work string through the borehole by extending a plurality of stabilizers from the work string. 18. The method of claim 17, wherein extending at least one extendable gripper element is extending at least one gripper element from an extended stabilizer. 19. A method of claim 12, further comprising: i) expanding a first packer device from the work string into sealing engagement with the borehole wall; and ii) expanding a second packer device from the work string into sealing engagement with the borehole wall at a location spaced apart from the first packer device, wherein expanding the first and second packer devices divides an annular space surrounding the work string into an upper annulus, an intermediate annulus and a lower annulus, and wherein exposing the port is exposing the port to the intermediate annulus.
