With a 26mm drilling capacity and a significant 2.7J impact energy, it delivers consistent performance for both professional construction sites and intensive home renovation projects.

Advantages

This rotary hammer stands out due to its high impact energy, which allows for efficient material removal and rapid drilling. The cordless design ensures maximum mobility, eliminating the need for proximity to power outlets and reducing cable-related hazards on the job site. Its ergonomic construction and compatibility with the unified SAS+ battery platform make it a versatile addition to any toolkit, providing reliable power delivery and long-term durability for frequent use.

• Professional construction and installation tasks

When it may not be suitable

This tool is not intended for heavy-duty industrial demolition of reinforced concrete structures or continuous, all-day professional drilling of large-diameter holes. For such extreme applications, a corded rotary hammer with higher impact energy may be more appropriate.

Key specifications

• Voltage: 18V
• Impact energy: 2.7J
• Maximum drilling diameter in concrete: 26mm
• Battery system: SAS+
• Tool holder type: SDS-plus

How to use

To operate the rotary hammer, ensure a fully charged SAS+ battery is securely clicked into the base of the tool. Select the appropriate drill bit or chisel for your task and insert it into the SDS-plus chuck until it locks into place. Use the mode selector switch to choose between drilling, hammer drilling, or chiseling depending on your requirements. Maintain a firm grip on the main handle and the auxiliary side handle, apply steady pressure, and engage the trigger to begin work.

What to consider before purchase

• Ensure you have compatible SAS+ batteries and a charger, as these may be sold separately.
• Verify that the 26mm drilling capacity meets the requirements of your specific project.
• Consider the weight of the tool for overhead or extended periods of use.

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and ear protection, when operating the rotary hammer. Regularly inspect the SDS-plus chuck for debris and apply a small amount of grease to the shank of your drill bits to ensure smooth operation and extend the life of the tool.
