The classic use for this auger is boring holes in turned lamp columns, but any spindle that needs a centered longitudinal hole is fair game. Assuming your lathe has a hollow headstock (or tailstock), and you're holding the workpiece with a hollow center, you simply insert the auger and gradually bore a hole to the depth you need, pulling back often to evacuate the chips. The cutting edge is designed specifically for working in end grain, and is easily resharpenend. Auger length is 27-3/4" (~70 cm).
