Real-life test: DeWalt DCD709 vs DCD778

Julien is renovating his house and working on several projects at the same time. This week, he needs to fasten wooden battens for a suspended ceiling and drill a few holes in a brick wall to install anchors. Both machines were used over the course of half a day, alternating between screwdriving, drilling in wood, and drilling in masonry.

Experience with the DeWalt DCD709?

The first impression is its compact size. The drill fits easily overhead or into ceiling corners. After an hour of driving screws, the lighter weight makes a difference: arms don’t tire as quickly. In brick, however, it shows its limits — speed is a bit lower, so it takes a little more effort to get through. Not a deal-breaker, but you lose a few minutes here and there. The LED with delay is a real plus when working in dark areas, like when fastening furring strips out of sight.

Experience with the DeWalt DCD778?

From the first holes in brick, it’s clear this machine is faster and more consistent, handling one hole after another with no hesitation. The single-sleeve chuck makes life easier, especially when switching constantly between a masonry bit and a screwdriver bit. On wood, the higher speed feels efficient right away. The trade-off is weight: with the battery attached, it starts to feel heavy after two hours, especially overhead. Its length can also be an issue in tight spots, where the 709 does better.

I use this drill for small jobs around the house. It’s really compact and fits everywhere, even in hard-to-reach corners. Too bad it loses a bit of speed compared to other models.

★★★★★

Sophie L.

Great grip, lightweight, and comfortable to use even for several hours. The torque is more than enough for my regular DIY projects. The LED with delay is a real plus.

★★★★★

Antoine R.

As a tradesman, I mostly use it for quick jobs. It’s handy and reliable, but I wouldn’t rely on it as my only tool for heavy-duty worksites.

Sturdy and powerful tool, I use it every day for light masonry and woodwork. The single-sleeve chuck makes bit changes fast and easy. A bit heavy with the battery, but nothing deal-breaking.

★★★★★

Claire M.

I often do DIY on weekends and this drill suits me well. It’s a little bulkier than I expected, but in return, the power and speed are there.

★★★★★

David B.

Good tool for professional use, solid and efficient. I do notice that the weight with the battery makes overhead work tiring more quickly. Otherwise, it does the job really well.
