The Dewalt DCF850 18V XR Brushless Impact Driver is an impressively compact power tool, measuring only 100mm in length, making it particularly good for working in small spaces. Ideal for a range of trades such as general purpose, interior installation, electricians, plumbers, HVAC engineers, carpenters and more, this is particularly useful for putting screws, bolts and more into various materials with force. Offering up to 205Nm of torque force, along with 3250rpm no load speed, this impressive impact driver includes an improved bit holder that prevents less run out when using it, as well as 3 different operation modes including precision drive for complete control. The variable speed trigger reduces the risk of over tightening while the LED ring light lets you see clearly the area youre working in regardless of external lighting conditions. At the heart of this tool is an improved 18V brushless motor that allows you to use the 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.
