Product Information
Full details
The Makita DHR202Z is a versatile 3-mode SDS hammer drill designed for professionals and serious DIYers needing efficient drilling and hammering capabilities. Its key benefit is the combination of power, precision, and user comfort in a compact package. A potential caveat is that it operates on LXT Lithium-Ion batteries, which must be purchased separately. This tool offers rotation only, hammering with rotation, and hammering only modes, alongside a torque limiter clutch, 360-degree chisel rotation, and an ergonomic design for reduced fatigue. It is also compatible with Makita's Stacking Connector Tool Case system.

FAQs
What type of bits does this hammer drill use?
The Makita DHR202Z uses SDS-Plus bits, which are specifically designed for hammer drills and offer a secure locking mechanism.
Does this model come with a battery and charger?
No, the Makita DHR202Z is a tool-only model. Batteries and a compatible LXT charger must be purchased separately.
What is the purpose of the torque limiter clutch?
The torque limiter clutch protects both the user and the tool. If the drill bit jams during operation, the clutch automatically disengages the motor to prevent sudden, forceful rotation that could cause injury or damage.
How do I change the chisel angle?
The chisel can be rotated 360 degrees with 40 distinct positions. To adjust, you typically need to pull back a collar or ring around the chuck, rotate the chisel to the desired position, and then release the collar to lock it in place. Refer to the user manual for specific instructions on your model.
What is the maximum capacity for drilling in concrete?
While specific maximum capacities can vary by bit type and material, this SDS hammer drill is designed for efficient drilling in concrete, masonry, and stone. For precise limits, consult the product's official specifications or manual.
Can I use this for general wood or metal drilling?
Yes, you can use the 'rotation only' mode with appropriate bits for drilling into wood or metal. It's important to select the correct bit type for the material being worked on.
Troubleshooting
Drill does not power on.
Ensure the LXT battery is fully charged and properly inserted. Check the battery contacts for dirt or damage.
Hammering function is weak or not engaging.
Verify that the tool is set to a hammering mode (hammering with rotation or hammering only). Ensure the bit is correctly seated in the SDS chuck. Check for any debris in the chuck mechanism.
Chisel is not rotating or locking in position.
Check if the mode selector is set correctly and if the chisel is fully inserted. Ensure the rotation mechanism is not obstructed.
Overheating during use.
Ensure ventilation slots are clear. Do not force the tool; allow the motor to work at its own pace. Take breaks during prolonged heavy-duty use.
