What Is a Rotary Hammer
A rotary hammer is a powerful tool that is used for drilling holes in hard materials such as concrete.
It is more powerful than a hammer drill and has a “hammer-only” mode without rotation.
The key difference between a rotary hammer and a hammer drill is the mechanical process for pounding action.
Rotary hammers provide more impact energy and are more durable compared to hammer drills.
They have three settings: drill mode, hammer drill, and just hammer.
Rotary hammers can also act as a mini jackhammer and have attachments for various jobs.
Professionals prefer rotary hammers over hammer drills for their heavy-duty performance.
Did You Know?
1. A rotary hammer, also known as a percussion drill or a hammer drill, is a powerful tool commonly used in construction to drill and break through tough materials like concrete and masonry.
2. Did you know that the concept of a rotary hammer was first developed in 1932 by Wilhelm Fein? He created the first-ever electric hammer to assist in breaking through solid surfaces.
3. Rotary hammers are different from regular drills in that they have a specialized mechanism that combines both hammering and drilling actions. This mechanism allows the tool to deliver a more powerful and efficient impact, making it ideal for heavy-duty applications.
4. While the rotary hammer is commonly used in construction, it also has some surprising applications in other fields. It is often used in archaeology to break through hardened soil layers and rocks during excavations, helping unearth ancient artifacts and structures.
5. Rotary hammers come in various sizes and types, depending on the specific task at hand. Some models are cordless, allowing for greater mobility on job sites, while others have additional features like adjustable speed and vibration control for enhanced precision and comfort.
Rotary Hammer Vs. Hammer Drill: Key Differences
When it comes to drilling, breaking, or chiseling through tough materials like concrete or masonry, having the right tool for the job is essential. While both rotary hammers and hammer drills are capable of handling these tasks, there are key differences that set them apart.
The main difference lies in the mechanical process for delivering the pounding action.
- Hammer drills use a mechanical action that combines rotation and percussive blows to efficiently break through materials.
- On the other hand, rotary hammers provide a more powerful action by utilizing an internal mechanism that delivers a piston-like pounding action.
- This pounding action allows rotary hammers to generate more impact energy, making them more suitable for heavy-duty tasks and preferred by professionals.
In summary:
- Hammer drills combine rotation and percussive blows for drilling, breaking, or chiseling.
- Rotary hammers provide a more powerful and piston-like pounding action, making them better suited for heavy-duty tasks.
It’s important to choose the right tool based on the specific requirements of the job to ensure efficient and effective results.
The Power And Durability Of Rotary Hammers
One of the primary advantages of using a rotary hammer is its superior power and durability compared to a hammer drill. Rotary hammers are engineered with robust motors that can deliver higher amperage, allowing for faster and more efficient drilling. The increased impact energy provided by rotary hammers enables them to tackle even the toughest materials, such as hardened concrete.
In addition to their raw power, rotary hammers are built to withstand heavy use. Their construction includes reinforced components and durable materials that ensure longevity and reliability in demanding work environments. This durability is particularly important when working with challenging materials that can place significant strain on the tool.
- Key advantages of rotary hammers:
- Superior power and durability
- Robust motors for higher amperage
- Increased impact energy for tackling tough materials like concrete
Rotary hammers are the ideal tool for professionals and DIY enthusiasts looking for a powerful and durable solution for their drilling needs.
The Three Settings Of Rotary Hammers
Rotary hammers offer users versatility through their three settings: drill mode, hammer drill, and just hammer.
In drill mode, the rotary hammer functions similarly to a regular drill, allowing for precise and accurate drilling into various materials.
The hammer drill mode combines rotation with a pounding action, making it ideal for drilling into concrete or masonry.
The just hammer mode allows the rotary hammer to function as a mini jackhammer. This setting is invaluable when it comes to breaking up concrete or chiseling away unwanted material.
These different settings give rotary hammers the ability to adapt to a wide range of construction and demolition tasks.
Choosing The Right Rotary Hammer: Factors To Consider
When selecting a rotary hammer for your specific needs, several factors must be taken into consideration.
-
The motor amperage is an important factor as it determines the power and speed of the tool. Higher amperage ratings generally indicate more efficient drilling and a faster work process.
-
Additionally, it is crucial to consider the comfort and feel of the drill in your hand, as this will directly impact your control and accuracy.
-
The durability of the chuck, the part that holds the drill bit, is another vital aspect to consider. A sturdy chuck will prevent wobbling and ensure consistent and precise drilling.
-
Furthermore, the chuck size determines the maximum recommended hole size that the rotary hammer can handle. It is worth noting that rotary hammers can often surpass the recommended hole size, but it is essential to use caution and follow the manufacturer’s guidelines.

Tips And Techniques For Using Rotary Hammers Effectively
Using a rotary hammer effectively involves employing the right techniques and taking specific precautions. To reduce friction and prolong the life of drill bits when drilling into materials like concrete, it is advisable to use a lubricant or water as a coolant. This helps prevent overheating and ensures smoother drilling.

While most rotary hammers and hammer drills come with a side handle and depth stop, do not overlook their importance. These accessories provide added stability, control, and depth adjustment, allowing for more accurate and controlled drilling. It is also essential to use proper ear protection, as rotary hammers operate at higher impact frequencies and noise levels.

Additionally, ensure you use proper ear protection due to the higher impact frequencies and noise levels.
When drilling larger holes than the recommended capacity, it is advisable to start with a smaller hole and gradually increase the size. This approach minimizes stress on the tool and helps ensure a cleaner and more precise hole. Additionally, when working with concrete blocks and using plastic anchors, using a backstop can prevent the anchors from being pushed through the material.

By inserting a chisel into the SDS holder of the chuck, a rotary hammer can effectively remove tiles or even demolish entire walls, adding to its functionality and usefulness in construction and remodeling projects.
What is the difference between a hammer drill and a rotary hammer?
The main difference between a hammer drill and a rotary hammer lies in their power and vibration levels. While both tools are designed to drill into tough materials, the rotary hammer is more robust and can deliver significantly more power than a high-end hammer drill. This increased power allows the rotary hammer to complete drilling tasks with much less rotation compared to a hammer drill, resulting in reduced vibrations that make it more comfortable to use. With its superior strength and reduced vibration, the rotary hammer offers a more efficient and user-friendly experience for heavy-duty drilling tasks.
Is a rotary hammer a jackhammer?
No, a rotary hammer is not a jackhammer, although the names are sometimes used interchangeably. Although both are heavy-duty tools, a rotary hammer is more similar to a jackhammer than a regular power drill. On the other hand, a hammer drill is a simpler tool that can be used for various drilling purposes, including wood and metal.
Will a rotary hammer break up concrete?
Yes, a rotary hammer is an effective tool for breaking up concrete. With its powerful impact force, the rotary hammer’s chipping bit can easily break apart smaller amounts of concrete and remove any excess material from surfaces. The in-line D-handle design adds to its capabilities, allowing for better control and precision during the concrete-breaking process.
