Tips for Choosing the Rotary Hammers
The first thing we want to make clear is that it is a power hammer, in this way we make sure that it really is the power tool you are looking for. Let’s get started! Power rotary hammers are known by several names, the most common are: Electro-pneumatic hammers, electric hammers, light hammers or combined hammers.
All of them are powerful power tools that are capable of both chiseling and drilling. Therefore it has the ability to drill and break hard materials. We must make it clear that the uses and capacities may vary depending on the model we buy, but as a rule with an electric hammer you can perform the following tasks.
- Raise both tiles, wall and floor.
- Chop and break all types of flooring for renovation.
- Drilling very hard materials such as reinforced concrete, to install large anchors.
- Roper and chop walls until completely demolished.
Power rotary hammers are tools that need power to work. Be it by cable or with a battery. Electricity allows the motor to perform two differentiated functions. On the one hand, it transmits the gears and teeth the power necessary to move the bits and therefore drill. On the other hand, thanks to a pneumatic piston, it is possible to generate the necessary force to carry out the knocking in the demolitions.
Power and strength
The power is expressed in watts (W) and the force in Joules (J). For tasks outside the professional field the most common hammers offer us from 1.2 to 15 joules, being able to reach 20 in the professional tools.
A power rotary hammer that allows us to carry out works of a certain size and with good value for money, are usually the models that offer us between 2.5 and 3.5 Joules, being more than enough for tasks outside the professional field.
The motor
We can find 2 different types of engines depending on where they are located. Electric hammers with horizontal motors tend to be lighter and give better results in roof work. With vertical motors it goes the other way, they have more weight and have great results in work, floor, and wall.
Weight and measurements
What you should know is that the more powerful hammers the more motor you need and therefore more weight and larger dimensions. A heavyweight hammer is usually tired of using it for a long time, so it is important that you really value what power you really need. To avoid buying very heavy and uncomfortable combined hammers, without need.
With cable or battery
As you will suppose the cordless models are easier to transport and therefore more comfortable and less dependent. But they are also more expensive if we want them with high powers.
On the other hand, the models with cable depend totally on a plug or extension to work being an impediment many times in works in the open air. But unlike with the cordless, we can get more powerful models with less money.
Frequently Asked Questions (FAQs)
1. What is a rotary hammer used for?
A rotary hammer is primarily used for drilling holes in stone and concrete. It can also be used for chiseling work, such as removing tiles or even demolishing walls. By inserting a chisel into the SDS holder of the chuck, the rotary hammer can perform various chiseling tasks.
2. What is the difference between rotary hammer and demolition hammer?
The main difference between a rotary hammer and a demolition hammer lies in their power and functionality. Demolition hammers deliver more powerful blows, typically having about 35% more power. They have fewer parts and sometimes a longer piston stroke. In contrast, rotary hammers offer a combination of drilling and chiseling capabilities.
3. Is a rotary hammer better than a hammer drill?
Yes, a rotary hammer is generally considered better than a hammer drill. It is more powerful and produces significantly less vibration, making it more comfortable to use. The rotary hammer also has a higher impact rate, providing faster and more efficient drilling and chiseling.
4. Can you use a rotary hammer to dig?
Yes, a rotary hammer can be used for digging hard soil. It comes with various chisels and accessories, including ones specifically designed for digging. By attaching the appropriate chisel to the SDS-Max chuck, the rotary hammer can effectively dig into the ground.
5. What are the advantages of a rotary hammer?
The main advantages of a rotary hammer are its powerful performance and reduced vibration impact on the arms. Rotary hammers are strong tools that provide less strain on the arms, making them ideal for larger projects. They are the preferred choice for many professionals.
6. Can a rotary hammer break up concrete?
Yes, a rotary hammer can break up concrete. It is one of the handheld tools that can be used for vertical and horizontal concrete work. However, the suitability of a rotary hammer for concrete breaking may depend on the specific model and the size of the concrete.
7. Can a rotary hammer be used as a hammer drill?
Yes, most rotary hammers have multiple settings, including a drill mode and a hammer drill mode. This allows them to function as mini jackhammers, providing both drilling and hammering capabilities.
8. What are the disadvantages of a rotary hammer drill?
There are two main disadvantages of a rotary hammer drill. First, they tend to be heavier than hammer drills, which can make them more tiring to use over extended periods. Second, rotary hammers cannot operate in battery mode and require a continuous power source. Additionally, the battery life of rotary hammers is often shorter compared to other power tools.
