Rotary Hammer Makita DHR182RTWJ

The Makita DHR182RTWJ rotary hammer is a compact, battery-powered tool designed for light to medium-duty drilling in masonry and concrete. Equipped with a brushless motor and SDS Plus chuck, it delivers reliable performance with a maximum drilling diameter of 1.8 cm in concrete. The tool operates at up to 1350 RPM no-load speed and produces an impact energy of 1.7 J, combining efficient drilling with manageable vibration and weight for overhead and confined-space work.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed designs, while the SDS Plus chuck ensures fast bit changes and secure bit retention. At 3.2 kg and compact dimensions (82 mm width, 301 mm depth), the tool is easy to handle and transport. Battery operation provides cordless convenience on sites lacking mains power and contributes to quieter operation and lower running costs compared with pneumatic or corded hammers.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Installing fixtures and fasteners in walls and ceilings
• Drilling openings for cable and pipe installations
• Work in confined spaces and overhead drilling where a lightweight tool is needed

How to use

Select an SDS Plus drill bit appropriate for the required hole diameter and material. Secure the battery according to the manufacturer’s instructions and fit the bit into the SDS Plus chuck until it locks. Position the tool perpendicular to the drilling surface, apply steady pressure, and start the tool at no-load speed; allow the hammer action to do the work rather than forcing the bit. For deeper holes, periodically withdraw the bit to clear debris and avoid overheating. After use, remove the battery and clean the chuck and vents to maintain performance.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection, and dust mask when drilling in concrete or masonry. Match battery capacity to the workload for sustained operation and use sharp, correctly sized SDS Plus bits for best results. For prolonged or heavy-duty tasks, consider breaks to prevent motor overheating and monitor bit wear to maintain drilling efficiency.
