A post hole digger works great for making holes for fence posts, provided the soil is sandy and does not contain a large quantity of rocks. Even with a heavy clay soil, the post hole digger will do a good job, but if you live in a place that is naturally rocky, you will need a wedge-point iron bar to break loose the rocks, a process that will save wear and tear on your post hole diggers.
A wedge-point digging bar is the official name for this handy tool that is used in many, different places by landscapers, demolition teams, carpenters and builders. The metal tool is about five feet long and it is drop-forged from iron and then heat-treated for superior strength. The digging bar has a weighted point that comes in handy for breaking up solid objects. Besides busting up big rocks in the ground, it can also be used for breaking up blacktop pavement, old concrete slabs and sidewalks, rotten wooden decks and porches. A tool like this weighs about a hefty 20 pounds, a sizable load, which is very necessary for its designed use.
Use for Digging Post Holes
A wedge-point iron bar can be a handy aid to the post hole digger, when making post holes in rocky terrain, for the digging bar does not really remove the rock, but rather it is used to either bust the rock apart or pry the rock loose. Once the rock is loose, it can be removed by hand and then you can continue digging with the post hole digger--at least until another rock is encountered. In some locations you may have to remove a lot of rocks until you reach the proper depth for the hole.
If by chance your fence installation activities takes you across an abandoned section of paved road or an old concrete slab, don't worry about removing the extra material, for the digging bar is just the right tool to punch a hole in the tarmac or the weathered concrete pad. All you need do is break up a small portion of the surface until you reach solid dirt. Then you can start your fence hole with the post hole digger.
The Handle End
The digging bar can be turned upside and the handle end, which usually has an expanded flat surface, can be used for tamping and compacting loose dirt or even wet concrete. This aspect of the digging bar might be most useful when it comes time to set the fence posts in place..
