With its 5 ¼” OD, this tool provides for greatly improved capabilities in combination with 6 to 7 ½” drill-bits and even larger under-reamers. The tool has a torsional capacity about double that of a 4 ¾” OD tool. The stroke capacity of 10” or 0.25m gives the tool a working range that makes it an optimal solution for high load performance-drilling. Tomax can provide an adequate overshot with the tool for use in 6 and 6 ¼” hole sizes.
The pressure loss through the tool is 150 psi at 350 GPM or 10 bar at 1300 lpm.
