Dewalt DCF885 18V Impact Driver + 1 x 4.0Ah Battery, Charger & DWST1-71195 Case

Product Information

Given that the DCF887 sits above the DCF885 in the DEWALT impact gun range, it isn’t surprising that it comes with a few added benefits. The impact driver’s variable speed of 0-2,800 RPM allows you to adapt the output to best suit each bit type, fixing type, and material that you’re working with.

It makes sense when you look at the stats of the respective types of tool. The torque output of the DEWALT DCD777C2 drill driver that we looked at previously, for example, sits at 500 in-lbs. Sounds good, but compare this to the impact driver at the center of this article (1,400 in-lbs) and there’s no contest! The DEWALT DCF887 is a premium, top-of-the-line cordless motor that’s designed to be the ultimate power source for your toughest jobs. It features a brushless impact driver. The brushless means more power efficient and less heat. The torque density of the motor is very high. That means the higher horsepower of the Dewalt DCF887 motor comes from the lower speed it spins at. The higher the torque density, the more power you can get from a motor with a given weight. It works with DEWALT’s range of 20V Max lithium ion batteries, with these being known to hold a higher energy density than standard batteries, helping the impact driver to run for longer between charges.

Conclusion

The Dewalt DCF887 cordless brushless motor is an excellent piece of engineering. It is a three-phase, electronically commutated motor with a permanent magnet rotor and a built-in sensor to determine shaft position. The shaft position sensor allows the engine to adjust for load variations and maintain constant speed under load. These days, there’s a lot of buzz about power tools, and the DEWALT DCF887 model is one of the most talked-about as it offers plenty of power to get the job done. The 12-Volt Max lithium-ion batteries are designed to keep the power flowing for long periods, so you don’t have to worry about it dying out in the middle of a job.

It features a three LED-light arrangement for maximum visibility and reduced shadows. The LED’s activate automatically once the trigger is pressed and stays on for 20 seconds following the release of the trigger. Nowadays, there’s no shortage of impact drivers available to help you handle the toughest of jobs when your drill driver just won’t cut it.

DeWalt DCF885 Features

As a result, no-load speed on the DCF887 increases to 3,250 RPM (versus 2,800 RPM on the DCF885), maximum torque grows to 1825 IN-LBS (versus 1400 LBS), and the number of impacts per minute increases to 0-3,800 IPM (versus the lower model’s 0-3,200 IPM).
