Vrtací kladivo Makita DHR241RTJ

The Makita DHR241RTJ rotary hammer is a battery-powered SDS Plus tool designed for drilling and light chiselling in masonry and concrete. Equipped with an 18 V power system and a motor reaching 1100 RPM, it delivers an impact energy of 2 J and can drill holes up to 2 cm in concrete. With a compact footprint (417 mm width, 84 mm depth) and a weight of 4 kg, the tool balances portability and job-site durability. The housing combines grey, blue and black finishes and the SDS Plus chuck enables quick bit changes.

Advantages

The DHR241RTJ offers cordless flexibility from an 18 V battery platform, reducing dependence on mains power and extension leads. Its 1100 RPM motor and 2 J impact energy provide efficient progress when drilling into concrete and masonry while maintaining controlled recoil. The SDS Plus system simplifies bit replacement and improves bit retention under repeated impacts. The tool’s relatively compact dimensions and 4 kg mass aid handling and positioning in confined spaces.

Suitable for

• Drilling 6–20 mm diameter holes in concrete and masonry
• Fixing anchors, dowels and threaded inserts in building construction
• On-site maintenance and light renovation tasks where cordless operation is required

How to use

Select an appropriate SDS Plus drill bit for the diameter and material, secure the battery and verify the tool is switched off before inserting the bit into the chuck until it locks. Position the bit perpendicular to the work surface, apply steady pressure and start at low speed to create a guide point, then increase speed as needed. Use the hammer function for drilling into concrete and masonry and disable it for plain drilling in wood or metal. After completing the hole, release the trigger and allow the bit to stop before removing the tool from the workpiece. Remove and store the battery when the tool is not in use.

Recommendations

For consistent performance and battery life, use Makita-compatible 18 V batteries with sufficient charge and observe manufacturer guidelines for duty cycles. Wear appropriate personal protective equipment such as eye protection, hearing protection and dust mask when drilling into concrete. For repeated or large-diameter holes, consider using cooled bits and allow the tool and battery to rest periodically to avoid overheating.
