Concrete is a super hard and dense building material which makes it one of the hardest building materials to be able to drill through. Without equipping yourself with the proper drill you will quickly find that you can burn yourself out.
With that said, I understand why you would want to know what the best hammer drill for concrete is. Or is a hammer drill even the right tool for the job?
That’s exactly what you are going to find out in this post… By the time that you are done reading this you’ll know if a hammer drill is even the right tool for your job and if it is, what hammer drill will be best for drilling concrete.
If you decide that a hammer drill is not the right drill for your specific application then we will go over what is the best type of drill for concrete.
Difference Between Hammer Drill And Rotary Hammer
Before we dive too deeply into this article I think we should start by going over the differences between a hammer drill and a rotary hammer drill.
Hammer drills and rotary hammer drills are both very similar in the way that they hammer the drill bit, in turn pulverizing the concrete while the bit spins. But the mechanisms that make them perform this hammering function are very different.
The hammering mechanism in a hammer drill is actually quite simple (pictured above). The way that this works is by using a set of toothed discs. When you apply force to the discs it causes them to rub one another, then separate and smash back down. This motion causes the drill to send hammering to the bit as it spins. See the demonstration below. This type of mechanism does not deliver that much punch.
Next, let’s look at how a rotary hammer drill delivers force to the concrete drill bit. you’ll notice that it is quite different.
You’ll notice how the rotary hammer uses a piston in order to deliver the hammering force to the drill. The piston offers a much more powerful blow than the disc system that the hammer drill uses. Which means that a rotary hammer is far more efficient when you want to drill larger holes in a shorter amount of time. Below is another style of rotary hammer.
Another important difference to mention is the chuck system that a rotary hammer drill uses compared to a regular hammer drill. Unlike the hammer drill the rotary hammer uses an SDS chuck which is designed to withstand more hammering action. It is also specifically designed to enhance the hammering feature of the rotary hammer drill while staying securely in place. See the SDS drill bits below.
What Type Of Drill Is Best For Concrete?
In general a hammer drill is designed more for less dense masonry such as brick or mortar. Whereas a rotary hammer drill is definitely a better choice if you are drilling concrete. With that said though, a hammer drill will certainly perform well enough for small concrete jobs.
That’s why this is kind of a loaded question. Although a rotary hammer drill is best for concrete it doesn’t mean that it is best for all applications or scenarios. It really depends on the task or number of tasks that you are looking to perform with your drill. That is like asking what is the best vehicle. You don’t know what the vehicle is being used for, is it speed, is it off roading, is it city driving etc. And until I know that it’s hard to choose. That’s why I have decided to give you a couple of questions to ask yourself before you choose the right drill for your needs.
3 Questions To Ask Yourself Before Choosing the Right Drill For Your Needs
Question #1: How often will you use a hammer drill? It is important that you decide realistically how often you will be using your drill. If you are a commercial contractor or serious DIYer then obviously you will have different needs than somebody who just plans on using it once and putting it on the shelf to rest.
For somebody who needs to drill a couple of small holes and may never need to use the features of a hammer drill again, a hammer drill will certainly suffice.
On the other hand, if you are a contractor or a serious DIY home owner who can see yourself using a hammer drill quite often a rotary hammer drill would certainly be your best bet. Even a cheap rotary hammer drill will far outperform ant regular hammer drill on the market.
Question #2: What size of holes do you need to drill into concrete? If you just plan to drill a couple small holes into concrete then it would be safe to say that you do not need to go with anything too extreme. If this is you then a hammer drill should do the job for you.
On the other hand, the last thing that you want to do is end up coming up short if you are drilling larger holes into concrete. Typically anytime you are drilling a hole 3/8″ or bigger you’ll find that a regular hammer drill will not cut it. You’ll need to use as rotary hammer drill for sure.
Question #3: Do you need an electric hammer drill or will a battery powered hammer drill serve you better?When deciding on a hammer drill for concrete you should consider whether you need battery or electric. So you need to look at few different things like, do you have access to power where you plan to drill because if you do not then obviously you should look at a battery powered drill.
Also, often times with battery powered drills you will run into a lack of power and not be able to get the job done or you will find that the job is too big and you will be changing out batteries often and slowing yourself down in the long run.
The Best Hammer Drill For Concrete
Now you should know whether you can make do with a hammer drill or whether you need a rotary hammer drill. But basically I’m sure that you understand by this point that a hammer drill is really only good for drilling small holes. Additionally their not great for drilling too many holes.
