When it comes to drilling into tough materials, having the right tool can make all the difference. Impact drills and hammer drills are two of the most popular power tools used for drilling into hard surfaces. But which one should you choose for your job?
In this article, we’ll take a look at the subtle differences between an impact drill vs hammer drill. This way, you can decide which one is best suited for your DIY project.
What Is An Impact Drill?

An impact drill or impact driver is a power tool that delivers strong rotational energy and rapid bursts of striking force to drive screws and drill holes. They work by combining a hammer function with a high-speed rotary motion, allowing them to drill into hard materials with ease.
It uses a rotating shaft that drives a hammer mechanism back and forth, creating a high-frequency impact force that is transferred to the drill bit. This hammering action allows the bit to break through hard surfaces such as concrete, masonry, and metal.
The Pros and Cons of Using An Impact Drill
One of the biggest benefits of using an impact drill is its ability to drill into hard materials quickly and easily. It is also great for driving screws, as the hammering action helps prevent stripping and reduces the risk of damaging the screw head.
Moreover, impact drills are lightweight and compact, making them easy to use in tight spaces. However, while quality impact drivers are great for drilling into hard surfaces, they may not be the best choice for softer materials such as wood or drywall.
The high-frequency impact force can cause damage to these materials, which can lead to splitting or cracking. Additionally, they tend to be louder and more vibrational than other types of drills.
When To Use An Impact Drill
Impact drills are best suited for heavy-duty tasks such as drilling into concrete or metal. They are also great for driving screws and other fasteners. If you need to drill into a hard material quickly and efficiently, this power drill is the way to go.
What Is A Hammer Drill?

A hammer drill, also known as a rotary hammer, uses a percussive mechanism to drill into hard materials. They have a piston-like mechanism that delivers rapid hammer blows to the bit, allowing the user to drill into hard surfaces with little effort.
The bit is also rotated at the same time, which is why it can break through hard surfaces more easily than a regular drill.
The Pros and Cons of Using A Hammer Drill
Hammer drills let you drill into hard surfaces quickly and easily. They are great for drilling holes in concrete and masonry. Typically, a decent hammer drill has a higher power output than other types of drills, which makes them ideal for heavy-duty tasks.
That said, you may have a problem with their weight and size. They are larger and heavier than other drills, which can make them difficult to use in tight spaces. Additionally, they tend to be more expensive because of their size and power.
When To Use A Hammer Drill
The best time to use hammer drills is if you’re handling heavy-duty tasks like drilling into concrete walls or masonry. You can use these essential household tools to make large holes in hard surfaces that may be too tough for an ordinary drill.
Impact Drill vs Hammer Drill: Comparison
The key difference between an impact drill vs hammer drill is the type of force used to drill into hard materials.
Impact drills use a combination of high-frequency rotational force and rapid bursts of striking force. On the other hand, hammer drills use a piston-like mechanism for rapid hammer blows to the bit.
To give you an overview of where these two power tools differ, check out the comparison table below:
| Impact Drill | Hammer Drill | |
| Features | High-frequency impact force Rapid bursts of striking force Great for driving screws and other fasteners Lightweight and compact design Not ideal for softer materials such as wood or partition wall | High power output Piston-like mechanism for rapid hammer blows Larger and heavier design More expensive |
| Tasks | Driving screws and other fasteners Drilling into hard materials such as metal and concrete Smaller and more compact design allows for use in tight spaces | Drilling into concrete or masonry Making large holes in hard surfaces Higher power output allows for faster and more efficient drilling |
Choosing the Right Tool for the Job
When deciding whether to get an impact drill or a hammer drill, there are several factors to consider. From personal preference to material type and how big your project is, it’s important to plan ahead.
Material Type and Thickness
If you need to drill into hard materials such as concrete or metal, you can use either of the two. However, if you are drilling holes in wood, drywall, or other softer materials, note that an impact drill’s high-frequency impact force can cause damage.
Project Scope and Complexity
If you have a large-scale project in mind that requires drilling into concrete or masonry, a hammer drill may be the better choice. This is due to its higher power output and ability to handle heavy-duty tasks.
In contrast, if you are working on a quick project or need to drill into tight spaces, an impact drill may be the way to go. It’s also the right choice for handling basic drilling tasks.
Personal Preference
Finally, personal preference plays a role in choosing the right tool for the job. If you are more comfortable using one type of drill over the other, that may be the deciding factor in your decision.
Safety Tips for Using Impact Drills and Hammer Drills
Impact drills and hammer drills are powerful tools that can cause accidents and serious injuries if used incorrectly. These include anything from flying debris to electrical hazards and hearing damage. Follow these guidelines to ensure your safety:
1. Wear eye and ear protection.
When using power drills, it is important to protect your eyes and ears from potential hazards and damage.
Impact drills and hammer drills generate a lot of noise and can produce debris that can be harmful if it comes into contact with your eyes. To protect yourself, always wear safety glasses or goggles, as well as earplugs or earmuffs.
2. Use the right drill bit for the job.
Using the wrong type of drill bit for the material being drilled can cause damage to the bit or the drill itself. It can also result in a poor-quality hole. Always use the appropriate drill bit for the material you are drilling into, and make sure that the bit is securely fastened in the chuck.
Also, beware of cheap drill bits, drill battery, and other drill accessories; only buy from trusted brands to ensure not only safety but compatibility.
3. Keep hands and fingers away from moving parts.
Power drills can be dangerous if they come into contact with your hands or fingers. Always keep your hands and fingers away from the moving parts of the drill. Also, make sure that loose clothing or jewelry is not hanging near the drill.
How To Use Impact Drills and Hammer Drills
It is important to practice proper usage of hammer drills and impact drills to prevent injuries and accidents. Here are some pro tips to keep in mind:
1. Apply steady pressure to the drill while in use.
When drilling, it is important to apply steady pressure to the drill to avoid damaging the bit or the material being drilled.
Make sure you apply enough pressure to keep the bit engaged with the material. However, avoid pushing too hard or applying excessive force, as this can cause the bit to break or damage the drill.
2. Do not apply excessive force or push too hard on the drill.
Applying excessive force or pushing too hard on the drill can cause the motor to overheat, the bit to break, or the material being drilled to crack or split. Use steady and consistent pressure, and let the drill do the work.
Should You Get An Impact Drill or A Hammer Drill?
Choosing the right power tool for your job can make all the difference in achieving a successful outcome. Impact drills and hammer drills are two of the most popular power tools used for drilling into hard surfaces.
By understanding the actual differences between these tools and considering the material type, project scope, and personal preference, you can choose the right tool for your job. Remember to always follow safety guidelines and proper usage and maintenance to prolong the life of your power tools.
