98 produce a spiral cutting action that breaks the soil up sufficiently to minimize clogging of large chunks of soil within vacuum passage 86 and or vacuum hose 88 vertically downward pointing nozzles 100 and 102 enhance the cutting action of the drilling tool by allowing for soil to be removed not only above a buried utility but in certain cases from around the entire periphery of the utility in other words the soil is removed above the utility from around the sides of the utility and from beneath the utility this can be useful for further verifying the precise utility needing service and if necessary making repairs to or tying into the utility digging tool 32 also contains a plurality of air inlets 104 formed in pipe distal end 94 that allow air to enter into vacuum passage 86 the additional air in combination with the angled placement of nozzles 96 and 98 enhances the cutting and suction provided by tool 32 returning to fig6 digging tool 32 may also include a control 106 for controlling the tool 39 s vacuum feature control 106 may be an electrical switch a vacuum or pneumatic switch a wireless switch or any other suitable control to adjust the vacuum action by allowing the vacuum to be shut off or otherwise modulated an.
