Product Information

Full details

The Makita DHR171RTJ 18V Cordless Brushless SDS Plus Rotary Hammer Kit is designed for professionals and serious DIYers needing a lightweight yet powerful tool for drilling into concrete, steel, and wood. Its key benefit is the efficient brushless motor, offering nearly double the runtime per charge compared to brushed models, combined with a compact, vibration-absorbing design for enhanced comfort. A potential caveat is its maximum concrete drilling capacity of 17mm, which may be limiting for very heavy-duty applications.

Extended Product Information

FAQs

What is the maximum drilling capacity in concrete?

The maximum drilling diameter in concrete for the Makita DHR171RTJ is 17mm.

What type of bits does this rotary hammer use?

This rotary hammer uses SDS Plus type bits.

How long does a fully charged 5.0Ah battery typically last?

The brushless motor is up to 50% more efficient, meaning a fully charged 18V 5.0Ah battery will last almost twice as long as a comparable model with a standard motor under similar usage conditions.

Can I use this tool for screwdriving?

This tool is designed primarily for drilling and hammer drilling. While it has variable speed, it is not optimized for screwdriving, and using it for this purpose may damage screws or the tool.

What is included in the kit?

The kit typically includes 2 x 5.0Ah batteries, a battery charger, a side handle, a depth stop, and a Makpac case with inlay.

Does it have a brushless motor?

Yes, the Makita DHR171RTJ features a brushless motor for improved efficiency and longer runtime.

What are the two operating modes?

The two modes are 'Rotary only' for standard drilling and 'Rotary Hammer' for drilling into masonry and concrete.

Troubleshooting

Tool won't start

Ensure the battery is properly inserted and charged. Check if the trigger lock is engaged. Verify the forward/reverse switch is in the neutral position when not in use.

Reduced power or speed

The battery may be low; try a fully charged battery. Check for any obstructions in the chuck or bit. Clean the ventilation slots.

Excessive vibration

Ensure you are using the correct mode for the material. Check if the bit is properly seated in the chuck. If vibration persists, the tool may require servicing.

Bit is difficult to insert or remove

Ensure the chuck is clean and free of debris. Rotate the bit slightly while inserting or removing. Use the one-touch sliding chuck mechanism correctly.

Pros and Cons

Pros

  • Extended battery life due to brushless motor efficiency.
  • Lightweight and compact for comfortable, prolonged use.
  • Reduced vibration enhances user comfort and control.
  • Versatile 2-mode operation for various tasks.
  • Easy bit changes with the one-touch sliding chuck.
  • Includes two 5.0Ah batteries, charger, and a Makpac case.

Cons

  • Maximum concrete drilling capacity of 17mm may not suit all heavy-duty needs.
  • Impact energy of 1.2 J is moderate, suitable for common tasks but not extreme demolition.
  • Requires 18V LXT batteries, limiting compatibility if you have other battery systems.
  • Cordless nature means runtime is dependent on battery charge.

Setup, Compatibility & Care Instructions
