Makita DTD171Z 18V Li-ion LXT Brushless Impact Driver - Batteries and Charger Not Included

Product Information

This one comes from the Makita G-Series and only works on lithium-ion battery platform. If you are a DIY person, then the device will meet or exceed your expectations. You must be thinking; How is that possible with an impact device available at such an affordable price?

Included charger has a forced cooling system. It has an inbuilt fan that brings down the heat level of a battery so that its internal cells improve and perform in a better way. New impact mode, 'Assist-Mode' drives slowly to start screw before full tightening to eliminate "screw cam-out" and "cross threading“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. Its electronically controlled 18V Li-ion battery is optimized to provide 50 per cent high runtime. The device is integrated with Battery Protection Circuit that keeps the cells safe in case of over-discharge, voltage spikes and high temperature. There is a push button to change the movement from forward to reverse and vice versa. For enhanced safety and convenience, the device has electric brakes as well as LED lights on its front. Moreover, it’s built with an ergonomic grip that gives you comfortable handling and minimum wrist stress.

The Makita DTD154 has 175Nm of fastening torque and the DTD171 has 180Nm of fastening torque. The difference isn’t really going to be noticeable, and if you are looking for more fastening torque and your main criteria, considering the price difference, the Makita DTD154 is better value for money. Impacts Per Minute and No Load Speed (RPM) If your job involves driving screws into concrete or hardwood, then the Makita DTD152Z can be your best alley. You might also want to consider a few other options we have mentioned as runner ups. In line with all new Makita tools the performance increases whilst the overall size of the machines decreases. Size, weight and ergonomics: Makita impact tools are generally compact and lightweight. But, they are available with various dimensions and heft. Slim options will be thin, which will not put much pressure on your wrists. So, choose a model that you can easily control and use. It will be better if the impact device has a soft and ergonomic grip for added convenience.

Available options

Brushless motor: The brushless design on this impact driver’s motor means that it continuously offers frictionless performance with little to no maintenance. This saw’s motor has a smaller number of moving parts, giving it the advantage of a more compact design. The DTD has a 1 mode which is the following: Tek Mode – This mode gives you full power at the beginning of driving the screw in, once the screw is almost all the way in, the impact driver reduces power to ensure the screw is flush, and to avoid over tingeing of the screw, and screw cam-out. Is it Worth Upgrading From The DTD154 to DTD171? Battery Protection Circuit keeps the cell safe, so none of the high voltage, extra temperature or over-discharge can harm it. As it uses lithium-ion technology, the device gets fade-free power. 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. TD111DSAJ is a boss tool to work with M5 to M14 standard bolts, M5 to M12 high tensile bolts, M4 to M8 machine screw, and coarse threaded screws 22 to 90mm. It has three impact modes: low, high and the latest A (Impact) mode. The advanced A method prevents any screws cross threading and cam-out by reducing the drive speed once the tightening starts.

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. Both Makita impact drives have the same impacts per minute at 3,800 and no load speed at 3,600. It’s quite disappointing that Makita did not increase these in the DTD171, however, 3,800 IPM and 3,600 RPM is still very good. Brushless Motor At the heart of this tool is the brushless motor that allows you to use the impact driver efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The Makita vs Dewalt rivalry is ancient and is justified. On the one hand, you have Japanese Innovation and then on the other Dewalt gives you the US-bred industry-leading tools. Off course, Dewalt is more American, but Makita has been the leader in Innovation from decades. Electronic 4-stage impact power selection providing a no-load speed of 3600rpm providing up to 3800ipm, the percussive action saving time and effort, driving screws up to 30% faster than a conventional drill/driver, no pilot hole is needed even into hardwood.Easily identified by its grey and blue colour, the device works well with standard screws measuring M4 to M8, M5 to M14 standard bolt, M5 to M12 high tensile bolt, and coarse thread of 22 to 125mm. Its 18V power offers 1.3 Amp of battery power and a runtime up to 60 minutes, only if you use the G-Series DC18WA charger (separately available). Makita is based in Anjo, Japan and yes they have a factory based in the United States, United Kingdom, Mexico and many other countries. Summary – Which Makita impact driver should I buy? Makita DTD154 is one of Makita’s best selling impact drivers in the UK, and now, it has been replaced by the Makita DTD171. If you are looking to replace your impact driver and wondering if it is worth spending extra on DTD171, we will compare them side by side to see the differences. Torque 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. Soft start adds to the ease of use while trigger controlled variable speed gives you complete authority over the material. LED lights are also in its front with pre-glow and after-glow functions.
