What do the Bosch model names mean?
There are 3 Bosch rotary hammer designations:
The designation “Bosch GBH” stands for “Gewerblicher Bohrhammer,” which translates to “Commercial Rotary Hammer,” and is used for all Bosch rotary hammers in the Professional series. The letters G, B, and H stand for “Gewerblich” (Commercial), “Bohr” (Drill), and “Hammer” respectively. This designation allows for quick recognition that these are professional rotary hammers specifically designed for commercial use.
The designation “Bosch 18V” refers to the required system battery for the Bosch rotary hammer, which has a voltage of 18 volts. The ampere strength, or battery capacity, can vary. For example, there are batteries with 2.0 Ah, 3.0 Ah, 4.0 Ah, or even 5.0 Ah. “Ah” stands for ampere-hours.
Ampere-hours indicate how many amperes the battery can deliver within one hour. For instance, an 18-volt battery with a capacity of 4.0 Ah can supply a current of 4.0 amperes to an 18-volt device for one hour. The higher the ampere-hours of the battery, the longer it can deliver power before needing to be recharged.
Bosch rotary hammers are identified by their model numbers, consisting of numbers. Using these model numbers, you can immediately determine the maximum drilling diameter that each rotary hammer allows. This gives you a quick overview of which rotary hammer can drill the largest hole.
Here are some examples:
- GBH 18V-21: This rotary hammer allows drilling holes with a maximum diameter of 21 mm.
- GBH 18V-26: With this model, you can drill holes with a diameter of up to 26 mm.
- GBH 18V-28: The GBH 18V-28 rotary hammer allows drilling holes with a diameter of up to 28 mm.
- GBH 18V-45: This rotary hammer allows drilling holes with an impressive maximum diameter of 45 mm.
By indicating the maximum drilling diameter in the model number, you can quickly select the appropriate Bosch rotary hammer that meets your requirements.
What does the Bosch impact energy in joules mean?
Joule is a unit of measurement for the impact energy or striking power of a rotary hammer. It indicates how much energy the rotary hammer transfers to the drill bit, thereby affecting the efficiency of drilling or chiseling. A higher joule value typically means greater striking force, resulting in faster and easier drilling or chiseling work.
Bosch and other manufacturers offer rotary hammers with different joule ratings, ranging, for example, from 1 to 12 joules. Choosing the right joule rating depends on the type of work you intend to perform with the rotary hammer. For smaller or less demanding tasks, a lower joule rating may be sufficient, while larger or more challenging projects may benefit from a higher joule rating.
It is important to select the appropriate rotary hammer with the right joule rating according to your individual requirements to achieve optimal results in drilling or chiseling.
The required joule rating for a rotary hammer depends on the type of work you intend to perform with it. Generally, the larger and harder the material, the higher the impact energy of the rotary hammer should be.
For light drilling in wood, plastic, or thin metals, rotary hammers with an impact energy of 1 to 2 joules are usually sufficient. For standard concrete work such as drilling holes for anchors, a rotary hammer with an impact energy between 2 and 4 joules is recommended.
However, if you have more demanding tasks such as drilling into hard concrete, stone, or masonry, or performing chiseling work, you should opt for a rotary hammer with a higher impact energy. In this case, rotary hammers with 5 to 8 joules or even more can provide the desired performance.
It’s important to note that excessive impact energy isn’t always necessary and can make the rotary hammer heavier and more cumbersome. Therefore, choose the joule rating according to your specific requirements and consider the material you intend to work with.
The required power of a rotary hammer depends on the type of work you intend to perform with it. The power of a rotary hammer is measured in watts and indicates how much electrical energy the device can convert per unit of time.
For general drilling in common materials such as wood, plastic, or thin metal, a rotary hammer with a power of around 500 to 800 watts is usually sufficient. These models are lighter and more compact, making them suitable for use in smaller projects or DIY tasks.
However, if you have more demanding tasks such as drilling into hard concrete, stone, or masonry, it is advisable to opt for a rotary hammer with higher power. Rotary hammers with powers of 800 watts and above are suitable for providing the necessary force and impact for these tasks.
It is important to note that power is not the sole criterion for the effectiveness of a rotary hammer. Impact energy (joules) and impact rate (blows per minute) are also crucial for the efficiency and success of your drilling work.
Ultimately, you should choose the power of the rotary hammer according to your specific requirements and the material you intend to work with. It can also be helpful to consult the manufacturer’s recommendations and the experiences of other users.
When drilling into concrete, the impact energy, measured in joules, is a crucial factor for the effectiveness and performance of a rotary hammer. Concrete is a hard material that requires high impact force.
For general drilling tasks in concrete, such as installing anchors or drilling holes for small fastenings, an impact energy of around 2 to 4 joules is often recommended. With a rotary hammer in this power range, you can easily handle most common drilling tasks in concrete.
However, for more demanding tasks, such as drilling larger holes or working on very hard concrete surfaces, it may be beneficial to use a rotary hammer with a higher impact energy of 5 joules or more. These more powerful models provide greater impact force and enable efficient drilling in harder concrete.
It is important to note that impact energy alone is not sufficient to determine the effectiveness of concrete drilling. The quality of the drill bit and proper application technique also play an important role. A high-quality drill bit designed for concrete, combined with the right feed pressure and suitable speed, can significantly improve drilling performance.
For specialized applications or particularly hard types of concrete, it may be advisable to use a professional rotary hammer with even higher impact energy or special features such as pneumatic impact control. In such cases, it may also be wise to consult with a professional to achieve the best possible result.
For drilling into concrete walls, a specialized concrete drill bit is typically used, as conventional wood or metal drill bits are not suitable for this purpose. A concrete drill bit features a special carbide tip designed for the hard surface of concrete, enabling efficient drilling.
When purchasing a concrete drill bit, you should look for the following characteristics:
Carbide Tip: The drill bit should have a carbide tip made of durable material that provides good drilling performance.
SDS or SDS-Plus Shank: For drilling into concrete walls, rotary hammers with SDS or SDS-Plus shanks are commonly used. Ensure that the concrete drill bit matches the corresponding shank of your rotary hammer.
Diameter: Depending on the size of the hole you need, choose a concrete drill bit with the appropriate diameter. Common diameters for concrete drill bits range from 4 mm to 20 mm.
Length: Select the length of the concrete drill bit according to the depth of the hole you intend to drill. Ensure that the drill bit is long enough to reach the desired depth.
Quality: Pay attention to the quality of the concrete drill bit and choose a product from a reputable manufacturer. High-quality concrete drill bits last longer, provide better performance, and are less prone to wear.
When drilling into concrete walls, it is also important to consider the proper drilling speed and feed pressure. Excessive speed or pressure can damage the drill bit or reduce drilling performance.
It is advisable to follow the manufacturer’s instructions and, if necessary, consult with a professional to achieve the best possible result.
Bosch rotary hammer with brushless motor
The brushless motor, also known as a Brushless Motor, offers several advantages compared to the conventional brushed motor. One of these advantages lies in the improved power transmission to the rotary hammer’s motor. As a result, the brushless motor runs more consistently and achieves higher efficiency.
In contrast to the brushed motor, the brushless motor does not produce friction, resulting in less heat generation and a longer lifespan.
User protection thanks to KickBack Control: 18 volt rotary hammers from Bosch
Both the Bosch GBH 18V-26 Professional and the Bosch GBH 18V-26 F Professional are equipped with the KickBack Control function. This feature detects sudden and unexpected rotations of the rotary hammer around the drilling axis, such as when the drill bit gets jammed in reinforced concrete.
In such cases, an integrated sensor shuts off the motor of the Bosch rotary hammer within a fraction of a second. This process reduces the risk of unexpected tool kickback and significantly decreases the risk of injury.
Bosch Quick-Change Chuck
SDS is the abbreviation for Special Direct System and refers to a clamping system developed by Bosch for power tools. It is specifically designed to allow for quick and tool-free changing of accessories such as drills or chisels.
The SDS system consists of a special attachment on the tool, equipped with a locking mechanism. This allows the accessories to be easily and securely inserted or exchanged without the need for additional tools such as a wrench.
The SDS system has established itself as a practical and time-saving solution for many applications in the craft and construction industries.
Differences between SDS, SDS plus, SDS max, and SDS-quick
The Special Direct System (SDS) is a particularly practical and uncomplicated clamping system for power tools developed by Bosch. It facilitates the quick exchange of various drill bits or chisels in corresponding machines.
The SDS Plus system differs only slightly from the original SDS system and serves the same purpose. It has been adapted to more powerful and heavier devices weighing 4 kg or more.
The SDS Max plug-in system is an advanced variant that is very popular due to its practicality, generating high demand for large and heavy rotary hammers. SDS Max is used for rotary hammers weighing over 5 kg.
In 2011, Bosch introduced the SDS Quick system, targeting lightweight and smaller rotary hammers. Examples include the Uneo* 10.8 V/12V model and the Uneo Maxx*, designed for DIY customers.
Bosch Rotary Hammer Settings
Depending on the model and features of the Bosch rotary hammer, various settings can be adjusted. Here are some possible settings that may occur with certain Bosch rotary hammer models:
Speed control: Some rotary hammer models feature adjustable speed, allowing the user to adjust the speed of the drill or chisel. This is particularly useful for adapting the drilling or chiseling performance to different materials or applications.
Impact force control: Some rotary hammer models allow for adjustment of the impact force. This enables the user to adjust the intensity of the hammer’s blows for both finer and coarser work.
Drill or chisel mode: Bosch rotary hammers often offer different operating modes such as pure drilling mode or chiseling mode. These modes allow the user to switch between different applications, such as drilling holes and material removal.
Stop function: Some rotary hammer models feature a stop function that immediately halts the drill or chisel when the user releases the corresponding button. This function enhances safety and allows for precise work.
Additional features: Depending on the model, Bosch rotary hammers may also offer additional settings or features, such as LED lighting to illuminate the work area or vibration damping to improve user comfort.
It’s important to consult the user manual of the specific Bosch rotary hammer model to learn about the specific adjustment options and their use, as these may vary depending on the model.
- Drilling
- Hammer drilling
- Chisel setting (alignment, rotation)
- Chiseling
If the rotary hammer has all 4 adjustment options, for example, you also have the advantage of being able to drill without hammer action.
Why could this be important? When drilling tiles, for instance, you definitely don’t want to use a rotary hammer, as it could cause the tile to shatter. In this case, having the capability to switch off the hammer action is a significant advantage. Otherwise, you might consider purchasing two separate machines.
