Real-life test: DeWalt DCD805 vs DCD999

Interior renovation site, fastening metal structures, drilling into solid wood and concrete walls. He compares two models in a single workday.

Experience with the DeWalt DCD805?

Julien starts his day with the DCD805 to install wooden battens. The tool is compact, lightweight, and easy to handle. In tight spaces, it fits right in. The torque is impressive: screws drive in firmly without forcing. After a long series of screwdriving, fatigue stays limited thanks to its reduced weight. On concrete, the hammer action does the job, but once the bit size increases, the tool quickly reaches its limit.

Experience with the DeWalt DCD999?

In the afternoon, he switches to the DCD999 with a FLEXVOLT battery. The difference is clear: steady, reassuring power, especially on concrete. The three speed settings provide real versatility, particularly when switching between wood and metal. However, the extra weight is noticeable, especially when working overhead with arms raised. The built-in light is useful in dark areas, but the bulkier design makes it less convenient in tight corners.

I mostly use it for home projects. The drill is compact, lightweight, and easy to handle. The torque is impressive for such a small size.

★★★★★

Sophie L.

As a craftswoman, I use it almost every day. The ergonomics are excellent, and the battery lasts well, but I wish it had a third speed for more precision.

★★★★★

Karim T.

Very practical on job sites where space is limited. The pivoting LED light is really helpful. The only downside: a bit limited for drilling large-diameter metal.

A real powerhouse with the FLEXVOLT battery. I can drill through metal and concrete without any problem. A bit heavy, but the stability makes up for it.

★★★★★

Laura B.

Used it for complete renovations. The 3 speeds make it easy to adapt to different materials. However, after several hours, the weight becomes noticeable.

★★★★★

David P.

Perfect for heavy-duty work, but for occasional use, it might feel a bit too bulky. The built-in light with delay is a real plus.
