The Dewalt DCF887 18V XR Brushless Impact Driver is a super lightweight and compact tool that is very comfortable to use and fits in small spaces. It is the first Dewalt impact driver to have a handy application control and gearbox which allows the user to choose the power of the torque theyd like depending on which material theyre using as a workpiece. The DCF887 can generate 3250rpm with an impact rate of 3800bpm, which are very impressive stats for a cordless 18V impact driver. Its been rated at a maximum of 205Nm of hard torque which is as equally impressive. The impact driver features 3 motor speed and torque settings to suit the need of the job in hand. There is also a precision drive mode for precise control whilst avoiding damage to both material and screw. A light ring of bright white LEDs improves visibility and function as a flashlight, helping to illuminate the workspace. Fast, one-handed fitment is also possible due to a drop in bit holder. 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 technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
