Best Post Hole Digger for Rocky Soil Guide

If you are a DIY enthusiast who’s into gardening, then you absolutely need an auger for digging holes around the home. The list above is not exhaustive of all the best post hole diggers for rocky soil you can find in the market. Different soil conditions also determine the type of post hole auger you will need for the job. This guide will go through the factors you need to consider when shopping for a post hole digger so you can get the best deal.

  1. The type of job to be done

This is the most important consideration you should have when shopping for a post hole digger. If it is light or medium-duty work such as planting a small bush, fixing a light fence, or setting up a mailbox, then there’s no need to invest in a very powerful hole post digger. However, heavy-duty and large scale projects such as installing a fence around your property and building a deck will need powerful post hole augers. If you are going to be using an auger in rocky soil, then you should get one that is up to the task.

  1. Engine power

The engine power will determine how fast and efficiently you can drill your holes. Most gas- powered post hole diggers have 2.5hp engines while electric ones offer 1200W of power output.
However, you find more powerful diggers if you have heavier projects. If you are looking to do basic work, then manually-operated post hole diggers would be a better option.

  1. The drill bit and its diameter

High-quality drill bits will add strength to your digging and make your work easier. Some diggers also come with a variety of drill bits for versatility when working on your project.
The diameter of the drill bit determines the size of your hole so if you are looking for larger holes then it is advisable to go for drill bits with bigger diameters.

  1. Depth capacity

Some post hole augers can only go up to 3 feet deep. Others can go up to 5 feet or even more. It is important to enquire about the depth capacity of a post hole digger before making a purchase.

  1. Weight and ease of handling

Most post hole augers are lightweight and therefore won’t be much of a problem operating or moving around with. But you will need to pay attention to the handles especially if you are going for the more powerful post hole diggers. They tend to have vibrations and without sturdy and ergonomic handles, your work can be a little difficult.


There are lots of options when shopping for the best post hole digger for rocky soil. However, you should make sure you find the right one for the kind of job you are looking to do. It should make your work easier so you don’t feel fatigued at the end of your project.
