The Makita HR1840 Rotary Hammer Drill is a robust tool designed for efficient drilling in various materials, ideal for serious DIY enthusiasts and light professional tasks requiring power and precision. Its 470W motor delivers strong performance with features like a torque limiting clutch for user safety and tool longevity. While it excels in drilling, users should note that despite the inclusion of a chisel set, this model does not feature a dedicated chiseling function.
Powerful 470W Motor: Delivers up to 2100 RPM for rotary drilling and 4800 BPM for hammer drilling, handling tough materials with ease.
2-Mode Operation: Seamlessly switch between "Rotary Only" for drilling in wood/steel and "Rotary Hammer" for concrete and masonry.
Torque Limiting Clutch: Enhances user safety and protects the gears by disengaging if the bit binds, preventing kickback and damage.
One-Touch Sliding Chuck: Enables quick and tool-free SDS-Plus bit changes, increasing efficiency on the job.
Depth Gauge: Ensures consistent drilling depth, crucial for precise and repetitive work.
Variable Speed Control Trigger: Allows for precise speed adjustments, adapting to different materials and applications.
Forward/Reverse Rotation: Useful for driving/removing fasteners (with appropriate accessories) or extracting stuck drill bits.
Lock-On Function: Provides comfort and reduces fatigue during prolonged use by allowing continuous operation without constantly holding the trigger.
High power output for its class, suitable for tough drilling.
Versatile 2-mode operation for various drilling applications.
Enhanced safety features with torque limiting clutch.
Quick and easy bit changes with one-touch sliding chuck.
Precise depth control with included depth gauge.
Comfortable for extended use thanks to the lock-on function.
Does not have a chisel function, despite a chisel set being included with some packages.
May be less suited for very heavy-duty concrete breaking tasks where a dedicated breaker is preferred.
Info needed: [Weight might be a factor for prolonged overhead work.]
Info needed: [Noise level or vibration dampening features are not specified.]

The Makita HR1840 is built for efficient drilling across a range of materials. Its 470W motor and 2-mode operation make it suitable for tasks from installing shelves in plasterboard (rotary only) to anchor bolt installation in concrete (rotary hammer).
For masonry work, the rotary hammer mode makes light work of drilling holes up to 18mm with TCT bits, 35mm with TCT core bits, and even 65mm with diamond core bits for plumbing or electrical conduit. In wood, it can drill up to 24mm, and in steel, up to 13mm, utilizing the rotary only mode.
The variable speed control is crucial for starting holes accurately and working with different material densities, while the forward/reverse rotation is handy for freeing stuck bits or even driving screws if used with appropriate attachments. The torque limiting clutch provides a safety net, automatically disengaging the gears if the bit encounters unexpected resistance, protecting both the user and the tool from sudden jolts. The depth gauge is invaluable for repetitive tasks, ensuring all drilled holes are consistent.
Setup:
Insert Bit: With the drill unplugged, pull back the one-touch sliding chuck collar, insert the SDS-Plus drill bit until it clicks into place. Ensure it's fully seated and can move slightly back and forth (this is normal for SDS-Plus).
Attach Depth Gauge: Loosen the side handle, insert the metal depth gauge into the designated hole, adjust to the desired drilling depth, and tighten the handle securely.
Power On: Plug the drill into a suitable power outlet.
Compatibility:
This drill exclusively uses SDS-Plus shank drill bits. It is compatible with a wide range of SDS-Plus bits for concrete, masonry, wood, and steel drilling.
It is not compatible with standard round-shank drill bits unless an SDS-Plus adapter chuck (sold separately) is used.
While a chisel set might be included with some packages, remember this model does not have a chisel function.
Care:
Cleaning: After each use, wipe down the tool with a dry or slightly damp cloth. Keep the ventilation slots clean to prevent overheating. Do not use solvents or harsh chemicals.
Lubrication: The SDS-Plus chuck mechanism benefits from occasional lubrication (e.g., silicone grease) to ensure smooth bit changes and prevent wear. Apply a small amount to the bit shank before insertion.
Storage: Store the drill in its case (if provided) or a dry, dust-free environment, away from direct sunlight or extreme temperatures.
Cord Inspection: Regularly check the power cord for any signs of damage. If damaged, have it repaired by a qualified technician.
Brush Replacement: Info needed: [Check manual for carbon brush inspection/replacement intervals.]
