How the Core Digger Works
- The Holey-Moley Core Digger is a vacuum assisted, manually operated hole-boring tool.
- It operates in loose to hard packed soils.
- This tool works well in soils dry to damp, with gravel, small rocks and in hardpan.
- Hard packed clay soils, loose soils and soils with up to 50% moisture are easy to penetrate.
- Tree roots can be cut with this digger.
- This Core Digger is easy to operate with only easy back-and-forth rotational movement. Soil plugs up to 15 lbs can be pulled in one operation.
- Your shop vacuum does the hard work. The vacuum removes the core cuttings from the hole while digging, and holds the soil plug in the digger for extraction. Then, reverse from vacuum to blower to extract the plug from the digger.
