Makita DHR283ZJ 18V x 2 LXT SDS-Plus 28mm Cordless Rotary Hammer

It delivers up to 28 mm drilling capacity in concrete, allowing for efficient work on masonry, stone, and concrete tasks without switching tools.

The DHR283ZJ has three modes: rotary hammer (for drilling and light chiseling in concrete), hammer-only (for chiseling and light demolition), and rotation-only (for drilling into wood, metal, and non-hardened materials). Choose the mode based on the task at hand to maximize efficiency and control.

The brushless motor provides higher efficiency and durability, which translates to longer battery life per charge and reduced maintenance needs, especially under heavy usage.

The SDS-Plus chuck allows quick, tool-free bit changes with secure bit retention, minimizing downtime and keeping you productive on long workdays.

Dual 18V LXT batteries provide sustained power for extended tasks and typically faster charging, helping you stay productive when working on demanding projects without frequent recharging.

AVT anti-vibration reduces tool-induced vibration during operation, resulting in better control, reduced fatigue, and more comfortable use during extended sessions.

Ideal for heavy-duty drilling and chiseling in concrete and masonry, including task like anchor drilling, core drilling, and masonry removal, as well as light chiseling tasks in stone and brick.

To change a bit, pull back the SDS-Plus collar, insert the new bit fully until it seats, release the collar, and ensure it’s locked. For faster setup, keep a small bit assortment ready and store bits in a tool belt or pouch for quick access. Always verify the bit is appropriate for the material and task.

Wear appropriate PPE (eye protection, hearing protection, dust mask/respirator, and gloves). Secure the workpiece, keep hands away from the chuck area, and use the correct bit for the material. Regularly inspect bits and battery contacts, and follow Makita’s safety guidelines for cordless demolition tools.

If you’re choosing between similar cordless SDS-Plus 28mm models, consider: 1) Makita DHR283ZJ (current model) for high power with dual 18V packs and AVT for comfort. 2) Makita DHR243ZJ (26mm class) for a compact alternative with strong performance in masonry drilling. 3) Makita DHR171Z (lighter, 13mm class) for less demanding tasks or extended run times where weight matters.

Consider the job scale, material hardness, and frequency of use. The DHR283ZJ offers high power, long runtime with dual batteries, and versatile 3-mode operation, making it well-suited for professional contractors who frequently work with concrete. If you need lighter duty or a budget option, smaller models or non-rotary hammer tools might suffice. Balance upfront cost against expected battery life, tool longevity, and the efficiency gains from AVT and brushless motor technology.
