Holey-Moley Digger Replacement Blades & Heads

Cat 6 Tools, LLC carries Holey-Moley Digger Replacement Blades and Heads for Post Hole Diggers.  In addition, with the universal adapter, all digger heads can easily be removed and interchanged with other digger heads by removing and replacing just four bolts.  The digger heads are available in 4-inch, 5-inch, and 6-inch diameters.

Interchangeability Makes Replacing Blades Easier

With interchangeable digger heads its easy to switch digger heads in just a few minutes. Due to the smaller size the 4-inch digger is ideal for metal posts for wire fencing. In addition, these smaller holes are ideal for small flag and mail box posts.

Held on with just four bolts, the 4-inch digger head is consequently easy to switch with a 5-inch digger head for digging perfectly sized holes for tight fitting 4×4 posts.  As a result,  5-inch holes are probably one of the best holes sizes for real estate signs and for wood posts. As a result of the tight fit, they require no concrete.

Finally, for the bigger jobs, it is easy to attach a 6-inch digger head to dig perfect holes for 4×4 posts with plenty of room for concrete or foam.  Finally, should you need a larger hole, our Reamers enlarge 6″ holes to 8″, 10″, or 12″diameters.

Holey-Moley Post Hole Digger Replacement Blades and Heads

The digger heads are even easier to exchange on the job, when you purchase a Lower Vacuum Tube Assembly with the digger head. These Quick Change Heads can then be quickly exchanged with other hole sizes.  All Holey Moley Digger Heads are interchangeable.
