Rotary hammer Characteristics

A rotary hammer is a versatile and powerful tool primarily used for drilling and chiseling concrete, stone, metal, and wood. It’s an essential tool for both professional tradesmen and DIY enthusiasts who need high-impact performance for heavy-duty tasks. A rotary hammer’s defining characteristic is its combination of rotary motion and a hammering mechanism, allowing for efficient drilling and chiseling through tough materials. In this article, we’ll explore the key characteristics and features of a rotary hammer, along with its technical specifications.

Powerful Performance for Tough Tasks

A rotary hammer is designed to handle the most challenging tasks with ease. Its high-impact force, delivered by the pneumatic hammer mechanism, enables it to break through tough materials such as concrete and stone. This hammer mechanism provides a significant advantage over regular drills, making the rotary hammer ideal for heavy-duty applications. Whether you’re drilling holes in a solid concrete wall or chiselling away at a stone surface, a rotary hammer’s powerful performance ensures you can complete the job efficiently.

One of the key features of a rotary hammer is the SDS-Plus system, which refers to the keyless drill chuck used for quick and easy bit changes. The SDS-Plus system offers better grip and torque transmission compared to traditional drill chucks, ensuring the bit stays securely in place during operation. It also allows for faster and more convenient tool changes, increasing productivity and reducing downtime.

Versatility with Central Selector Switch

Rotary hammers are designed with a central selector switch that allows users to easily switch between different modes depending on the task at hand. The main functions available on the rotary hammer include:

1. Drill Mode: This is the standard mode used for regular drilling tasks. The hammering mechanism is not activated, and the tool operates like a standard drill.

2. Hammer Drilling Mode: In this mode, the hammer mechanism is engaged, and the tool provides both rotational and hammering action to drill through harder materials like concrete and stone.

3. Chiseling Mode: The hammer mechanism is also engaged in this mode, but instead of drilling, the tool is used for chiseling tasks, such as removing tiles or breaking up concrete surfaces. The chisel position can be easily adjusted to suit the task, adding further versatility to the tool.

4. Adjusting Chisel Position: This feature allows the user to rotate the chisel in the tool, adjusting its angle to achieve the desired work position when chiseling. This gives users precise control over the tool’s operation.

With this central selector switch, users can seamlessly transition between these functions, making the rotary hammer a flexible solution for various tasks.

Ergonomics and Comfort

When using a rotary hammer for extended periods, comfort and ease of use are essential for reducing fatigue and ensuring precise operation. The tool is designed with anti-slip soft grips that provide added comfort during use, minimizing hand strain. The ergonomic design ensures that the user can hold the tool securely and comfortably, even during long work sessions.

The front handle of the rotary hammer is also rotatable, offering a 360° adjustment for improved control. This feature allows the user to adjust the handle to suit their grip and working position, whether they’re drilling overhead or working in tight spaces. The rotating handle helps to distribute the weight evenly, making it easier to manoeuvre the tool for precise drilling and chiselling.

Additionally, the tool includes a carrying case for easy transport and storage. The case helps keep the rotary hammer and its accessories organized, ensuring that everything is in one place when you need it.

Included Accessories

The rotary hammer is supplied with a variety of accessories to help users get started right away. These include:

• 1 flat chisel (250 mm): Ideal for chiselling tasks such as breaking concrete or removing tiles.
• 3 drill bits (Ø 6/8/10 mm x 150 mm): These drill bits are perfect for drilling holes in various materials, including concrete, stone, metal, and wood.
• 1 metal depth stop: This accessory ensures accurate drilling depth, preventing over-drilling and improving the precision of the work.
• 1 keyless drill chuck for round shank drills: This chuck allows you to use standard round shank drill bits, expanding the range of tasks you can tackle.

Technical Data: Key Specifications

The performance of a rotary hammer is determined by its technical specifications. Here are the key technical data for the rotary hammer:

• Rated power consumption: 800 watts, which provides sufficient power for heavy-duty applications while maintaining efficiency.
• Impact force: 1.2 joules, delivering sufficient force for effective drilling and chiselling.
• Impact rate: 0–7500 min^-1, which refers to the number of impacts per minute. This high rate of impact ensures quick and efficient work on tough materials.
• Idle speed: 0–1650 min^-1, indicating the maximum rotational speed of the drill bit when the tool is not in hammer mode.
• Maximum drilling diameter:
  • 19 mm in concrete and stone
  • 13 mm in metal
  • 24 mm in wood
