Dewalt DCF787 vs DCF887 – How do they compare?
Design and Build
In terms of look, impact drivers are no exception from the lack of standard rules of how they ought to look. Since they’re all from the same manufacturer, they come with the same Dewalt look with the ever-present yellow and black colors. They’re both cordless and use rechargeable 20V lithium-ion batteries. On chuck size, they both use a ¼ inch chuck for holding the bits and screw bits in place without a key. A brushless motor can also be found on both models giving you efficiency and more runtime. They also come with LED lights for illumination.
However, the differences are noted when it comes to dimensions, the number of batteries used, weight, and their respective lengths. The Dewalt DCF787 measures 12.5 x 3.75 x 9.81 inches with a weight of 2.8 pounds without a battery and a front-to-back length of the head of 5.55 inches. It also features a single LED light and uses a single Lithium-ion battery for power. On the other hand, the Dewalt DCF887 uses two Lithium-ion batteries, weighs 2 pounds, and has dimensions of 16.22 x 4.5 x 10.1 inches with a length of 5.3 inches from the front to the back. For lighting, it offers 3 LED lights.
Due to its lightness because of a single battery and a smaller dimension, the Dewalt DCF787 is the better impact driver over the DCF 887.
Speed and Performance
The heart of an impact driver/wrench is the power and speed. How fast and efficiently an cordless impact driver can drive and fasten screws into materials like wood and concrete is how its sheer power is determined. Both of these impact drivers deliver the expected performance. Both models come with a brushless motor for extended durability and improved runtime.
Dewalt DCF787 delivers a torque of 1500 inches/pounds and maximum speeds of 2800 revolutions per minute (RPM) and 3200 impacts per minute (IPM) using a variable trigger to drive those carriage bolts and long deck screws into any wood as well as concrete screws into any wall. To make this happen, it has a keyless chuck with a ¼ – inch diameter that accepts bit tips of up to 1-inch diameter and holds the screw bits in place. It also comes with an LED light for visibility.
The Dewalt DCF887 on the other hand uses its two 4.0Ah batteries with a fast charger to deliver 3 no-load speeds of up to 1000 RPM, 2800 RPM, and 3250 RPM and uses a speed selector to control and adjust these speeds. As if that’s not all, it also delivers a maximum torque of 1825 in-lbs to handle any screw driving tasks within its range. It also uses a chuck of ½ inches and can hold up to an inch bit tip. Dewalt decided to be more generous with 3 LED lights for sufficient lighting to improve your accuracy and precision in those tight spaces and even at night.
The Dewalt DCD887 has more speed settings, a higher speed, and maximum torque, coupled with its 3 LED lights gives it a competitive edge over the DCD787.
Both models come with accessories in the set. The Dewalt DCD787 comes with a 1.5Ah Lithium-ion battery, a fast charger, and a bag to carry the impact driver and other tools giving you the desired portability. Dewalt DCD887 too comes with a case and a faster charger with the difference being the number of batteries. It comes with two 4Ah batteries and a belt hook. Despite both of them having almost the same type of accessories, Dewalt DCD887 comes with two higher amperage batteries and a belt hook. These accessories make it a better impact driver.
