Product Information
Full details
The Makita DHR243Z is an 18V LXT Cordless Rotary Hammer Drill designed for professional tradespeople requiring powerful and efficient drilling in concrete and masonry. Its key benefit is high productivity with reduced energy loss thanks to its brushless DC motor and the convenience of a quick-change chuck for SDS-plus bits. A potential caveat is that it is a 'Bare Tool,' meaning battery and charger are sold separately, requiring an existing 18V LXT battery system.

FAQs
What is the main advantage of the brushless motor?
The brushless DC motor provides higher productivity by reducing energy loss by up to 30%, leading to more power and longer run time per charge.
Does this tool come with a battery and charger?
No, the Makita DHR243Z is sold as a 'Bare Tool.' A compatible Makita 18V LXT battery and charger must be purchased separately.
What type of bits does this rotary hammer use?
This rotary hammer uses SDS-plus bits. It features a one-touch slide chuck for easy bit installation and removal.
What are the three modes of operation?
The three modes are: Rotation + Hammering (for drilling into concrete/masonry), Hammering only (for chiseling), and Rotation only (for general drilling with standard bits, using an optional chuck adapter).
How does the vibration-absorbing construction benefit the user?
The unique rubber joint construction suppresses vibration transmitted to the battery terminals, which minimizes battery failures and improves overall tool durability.
Can I use standard drill bits with this tool?
You can use standard drill bits by purchasing an optional SDS-plus chuck adapter. In its standard configuration, it is designed for SDS-plus bits.
What is the purpose of the included 5-piece SDS set + chisel?
This set provides essential SDS-plus bits and a chisel for immediate use in various drilling and light demolition tasks, allowing you to start working right away.
Troubleshooting
Tool does not power on
Ensure the battery is fully charged and properly inserted. Check for any obstructions around the battery contacts.
Drilling performance is slow
Verify that the correct mode is selected for the material. Ensure the SDS-plus bit is sharp and free from damage. Check that the battery is sufficiently charged.
Chuck is difficult to change
Ensure the bit is fully inserted or removed by pulling back the chuck sleeve. Clean any dust or debris from the chuck mechanism.
Excessive vibration
Check if the tool's vibration-absorbing components are damaged. Ensure you are using genuine SDS-plus bits and that they are properly seated.
