Fence Post Hole Reamer 12 inch

The Post Hole Reamer enlarges 6-inch diameter holes to 12-inches.  Other diameters are available – 10 inch, and 8 inch.  In addition, the all steel reamer has a movable cutting blade.  As a result, in the up position, the 6-inch pilot tube is exposed for starting holes.  Consequently the reamer stays perfectly aligned.  After starting a hole, it’s easy to move the blade to the down position.  As a result, In the down position, the blade will cut a square bottom in the hole.

This reamer works with the same Shop Vacuum as the Holey Moley Diggers.   The vacuum removes cuttings from the bottom of the hole while reaming.  This significantly reduces the time on cleaning up holes.    In addition, the clean holes with uniform sides reduce the amount of dirt removal required for each job.
