Rotary Hammer Makita DHR241RTJ

The Makita DHR241RTJ rotary hammer is a cordless 18 V tool designed for drilling and light chiselling in masonry and concrete. It combines an SDS Plus chuck system with a compact form factor and a no-load speed of up to 1100 RPM. With an impact energy of 2 J, this rotary hammer drills holes in concrete up to 20 mm diameter while offering a balance between portability and performance. The tool’s overall dimensions and a weight of approximately 4 kg provide stable handling for repetitive tasks without excessive operator fatigue.

Advantages

The SDS Plus system ensures quick bit changes and secure seating, reducing downtime during site work. Battery operation removes the need for power cords, increasing mobility on construction sites and in confined areas. The tool’s 1100 RPM no-load speed combined with 2 J impact energy delivers consistent drilling progress in medium-density masonry and reinforced concrete where small to medium diameter holes are required. Its compact dimensions facilitate access in tighter spaces and improve control during precision drilling.

Suitable for

• Drilling 6–20 mm holes in concrete, brick and block
• Installing anchors, dowels and wall fixings
• Light chiselling and small repair jobs
• Work in areas without ready access to mains power

How to use

Install a compatible SDS Plus drill bit of the appropriate diameter for the task and secure the battery before operation. Select the drilling mode if the tool offers multiple functions, then position the bit perpendicular to the work surface. Apply steady, moderate pressure; allow the tool’s impact mechanism and speed to progress the hole rather than forcing the bit. For repetitive drilling, withdraw the bit periodically to clear dust from the hole. After finishing, switch off the tool, remove the battery and store the rotary hammer and bits in a dry place.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. For improved hole quality in reinforced concrete, start with a smaller pilot hole before increasing to the target diameter. Keep battery packs charged and be aware of tool temperature during extended use to avoid overheating.
