Rotary hammer Makita DHR242Z, cordless 18 V Li‑Ion, drill Ø concrete 24 mm, weight 2.7 kg, soft grip

The Makita DHR242Z rotary hammer delivers high power in a compact design for drilling and light chiselling tasks. Equipped with a brushless DC motor for improved power-to-weight and power-to-size ratios, it reduces heat buildup during prolonged operation. The tool accepts 18V Lithium-Ion batteries (battery sold separately) and is designed for use with Makita’s DX01 Dust Extraction System for dustless drilling in sensitive environments (DX01 sold separately). It features a torque limiter to stop bit rotation if the bit jams, a rubber joint that reduces vibration transmission to the battery, and a plastic housing bumper to protect the mode selector and gear housing.

Advantages

Brushless DC motor improves efficiency and reduces maintenance while enabling prolonged high-production use. Quick attachment to Makita’s DX01 Dust Extraction System allows safer, cleaner drilling. The torque limiter increases operator safety and prevents damage to the tool and bits. Rubber joint construction reduces vibration transfer to the battery, lowering the risk of terminal breakage or poor electrical contact. A one-touch sliding chuck simplifies bit changes, and the 40 angle bit positions provide flexible chisel orientation. Ergonomic soft rubber grip absorbs vibration for more comfortable handling.

Suitable for

• Drilling into concrete, masonry and brick
• Light chiselling and chip-off work
• Drilling metal and wood when using appropriate bits
• Dust-sensitive job sites when paired with DX01 dust extractor

How to use

Install a compatible 18V Makita battery and secure the desired drill or chisel bit in the one-touch sliding chuck. Select the operating mode and angle position for the bit (40 angle positions available for chiselling). For dust-minimized operation, attach Makita’s DX01 Dust Extraction System before drilling. When drilling, apply steady pressure without forcing the tool and allow the brushless motor to maintain consistent speed. If the bit jams, the torque limiter will interrupt rotation—release pressure and remove the bit before resuming work. After use, remove the battery and store the tool in a dry place.

Usage recommendations

Use the Makita DHR242Z with compatible SDS-plus bits for optimal performance, wear appropriate PPE (eye, ear and dust protection), and pair the tool with the DX01 dust extractor in environments requiring dust control. Regularly inspect the chuck, mode selector and battery terminals for damage and keep ventilation areas clear to avoid overheating.
