Rotary hammer Makita DHR243Z — 18V cordless, SDS, 2 J impact energy, 3.4 kg, 950 RPM, 4,700 bpm

The Makita DHR243Z rotary hammer is an 18 V battery-powered tool designed for drilling and light chiselling in concrete, masonry and similar materials. It combines a brushless DC motor with compact dimensions (88 mm width, 482 mm depth) and a lightweight build of 3.4 kg, delivering up to 950 RPM, 4,700 bpm impact rate and 2 J impact energy for efficient work on construction and renovation tasks.

Advantages

The brushless DC motor reduces energy loss by approximately 30% and improves runtime and durability. A one-touch sliding SDS Plus chuck and included quick-change drill chuck simplify bit changes. Variable speed trigger and a torque limiter provide precise control over drilling speed and load. Ergonomic handle design and a natural-position mode selector with 40 different bit angle settings enhance handling and accuracy. Unique rubber joint construction and vibration-absorbing cushion rubbers separate the housing and minimise vibration transmission to the battery terminals, reducing battery failures. The tool supports 3-mode operation (rotation+hammering, hammering only, rotation only) and is compatible with 1.5, 3.0, 4.0 and 5.0 Ah Lithium-Ion batteries.

Suitable for

• Drilling holes in concrete and masonry
• Light chiselling and demolition work
• Tight-space drilling where a compact rotary hammer is needed
• Construction and renovation tasks requiring variable speed and impact control

How to use

Fit a compatible SDS Plus bit into the one-touch sliding chuck or attach the quick-change drill chuck for standard bits. Select the desired operating mode on the mode selector and set the bit angle if required. Use the variable speed trigger to control RPM and the torque limiter to avoid overloading the tool. Hold the ergonomic handle with a firm grip and apply steady pressure while drilling; allow the tool to do the work rather than forcing it. Change or charge Lithium‑Ion batteries according to the battery manufacturer’s instructions.

Recommendations

For optimal performance and longevity, use recommended Makita Lithium‑Ion batteries in specified capacities, wear appropriate eye and hearing protection, and allow the tool to cool periodically during extended use. Store and transport the tool in a dry environment and inspect bits and chucks regularly for wear.
