Real-life test: DeWalt DCD777 vs DCD778

Jean is renovating a small outbuilding attached to his house. The day’s plan: build a wooden frame for a false ceiling, fix battens, and drill a few anchors into a hollow brick wall. The work is spread over half a day, alternating between screwing, drilling, and moving around in a tight space.

Experience with the DeWalt DCD777?

Jean starts by assembling the wooden elements. The DCD777 proves very pleasant to use: lightweight, well-balanced, and precise thanks to its numerous torque settings. After an hour of continuous screwdriving, fatigue is minimal thanks to its low weight. On metal, it remains steady and doesn’t show any particular weakness. However, when he tries to drill into the brick wall, the lack of a hammer function quickly becomes obvious: the tool isn’t designed for this type of material and reaches its limits fast.

Experience with the DeWalt DCD778?

Jean continues the project with the DCD778 to secure the battens into the masonry. The hammer mode makes a clear difference: the drill goes through the brick effortlessly, even with medium-sized bits. The keyless chuck speeds up bit changes, saving him time. On the downside, the slightly higher weight becomes noticeable after two hours, especially when working overhead. Still, the ergonomics and rubberized grip provide a solid hold and help reduce discomfort.

I use the DCD777 for DIY projects at home. It’s lightweight and easy to handle, especially in tight spaces. Too bad it doesn’t have a hammer function, but for wood and metal it gets the job done perfectly.

★★★★★

Sophie R.

Great grip and precise torque settings. I really like the 4 Ah battery, it lasts well even during intensive screwdriving. It’s become my go-to tool for small renovation jobs.

★★★★★

Karim D.

I chose it for its light weight and compact size. Ideal for quick tasks, but during longer drilling in harder materials it does reach its limits.

Lucie M.

The hammer function is a real plus, I was able to drill into brick without any issues. The keyless chuck is convenient, even with gloves on. A bit heavier than I expected, but still manageable.

★★★★★

Julien P.

Good versatile tool, works well for my professional needs on-site. However, the 2 Ah battery drains pretty fast if you drill continuously. I had to invest in a larger battery for more comfort.

★★★★★

Andréa C.

I mostly use it for furniture assembly and some renovation work. The ergonomics are excellent, and the LED light is very handy. The only downside: it’s a bit long, which makes it tricky in tight corners.
