Ric, that is the "Roto Pruner" attachment for McCulloch units. The idea was to cut the branches without tearing or splintering the cut. I have seen them in literature with a pole extension so you could reach up in the tree as needed. They were promoted at spining at 6,000 RPM, but with one direct connected to a BP-1 you might be able to double that!

I dunno Mark, that may be for Sugar Maples ..... that 'guide' attachment is actually upside down. Flip it up and the bit must go upwards at a 45 degree angle. Pull out the drill and insert the tube, hang your sap collection bucket on there and you have it.
