This will depend on what you plan to use it for. Power and size wise, you will not really notice the difference between the two. However, when it come to precision and control, The DTD171 is the best Makita impact driver for this. The DTD171 gives you more pre-set power options, as well as 4 assist mods for different types of jobs. Their HQ is in Japan. Their Telford manufacturing plant is the only full-production facility for power tools in the UK and has been successfully running construction on many of our top line cordless power tools since 1991. The majority of our product range is battery powered, but our energy source is the customer’s satisfaction. Compact design and ergonomic rubber soft-grip handle allow for comfortable use. Powerful 4-pole motor. Features a variable speed trigger and LED worklight with afterglow function. Ideal for all trade applications. The MAKITA DC18RC has a cooling fan that blows cool air into the battery.

The Makita DTD171 has 4 pre-set speed settings, and they are: Max: Power Selection: The cordless impact driver has electronic 4-stage impact power selections to choose from. This allows you to have complete control of the tool thanks to the variety of power levels, allowing you to adjust the power depending on the task at hand. The new Makita DTD170 impact driver is technically a 6-function impact driver, with four speeds and matched impact power: then the newly introduced operating mode, 'T-Mode' is used for tightening self-drilling Tek screws and the new A-Mode (Assist mode) which, when selected starts the rotation slowly allowing maximum control of the screw as it starts to bite into the material. Once the impact driver detects the screw tightening it switches to full speed and full impact power to complete the tightening sequence. The A-Mode is designed to eliminate ‘screw cam-out’ and ‘cross threading’ caused by high speed rotation before the screw bites in the material. Electric Brake: The 18v brushless driver has an electronic brake control, so the motor will stop and cut out as soon as the trigger is released. This allows the power tool user to have complete control when on the job.

When you have a big job on then it makes sense to go for the biggest battery. So I would suggest the 6ah battery which is the most powerful in the range. The new top-of-the-range Makita DTD171 impact driver has a compact overall body length of just 117mm and weighs only 1.5kg. Works with all power tools that feature a yellow connector plate or has a star on the connector plate The A-Mode is designed to eliminate screw cam-out and cross threading caused by high speed rotation before the screw bites in the material. If you haven't had one of these drivers before then I would suggest you give them a try. Most people wonder how they ever did without them as they are so much better than a standard drill.

In line with all new Makita tools the performance increases whilst the overall size of the machines decreases.
