Digging Post Holes in Solid Rock 

There are many pieces of advice for drilling post holes in solid rock. First off is that the best post hole auger will NOT be able to dig post holes in solid rock.  So ditch that idea.

The easiest ways are to think outside the box.  Think for solutions out the box instead of a fence.  

Do you really need a traditional fence or could you plant a fast-growing hedge or even make a rock wall fence instead?  Maybe it would require less maintenance or look better with your landscaping?  Maybe, you could even save yourself some cash AND not have to dig fence post holes in rocky ground?   

Some types of rock are easier to drill and others, are, well, as hard as a rock can be. 

Consider Hiring a Professional 

You have the option to call in professionals who drill in these sorts of conditions.  They have the know how and the expensive equipment to deal with digging post holes in solid rock.  It could even be the same price as renting or buying all the special equipment to do it, not to mention save you a ton of time.  Have the holes drilled for you in no time and without any effort on your part. 

Can you tell we are trying to make this easier for you?  Frankly, I would find any way to avoid digging post holes in solid rock. 

If you absolutely must drill into solid rock, the deeper the hole, the more labor and more expensive tools you’ll need.  For shallow holes, you can probably use a hammer drill.  For deeper holes, you will need a jackhammer, a drifter drill and maybe, even dynamite.  Careful with all of the above.  If you are not confident with these sorts of tools, hire someone. 


Digging post holes in solid rock is not something I ever want to do myself.  This is one of those jobs where you just bite the bullet.  Pay the Pros.  They will be in and out with all the top-notch gear and you’ll have perfect post holes in solid rock.
