DeWalt 20V Max Compact Drill/Driver Kit DCD771C2 Review

This drill finished just behind the Milwaukee M18 and ahead of the Porter-Cable PCCK607LB. The DeWalt DCD771C2 is in the middle of these two drills in terms of list prices, but it did the worst in our battery life performance tests of this group. However, it is the best at driving in this trio and better than the Porter-Cable when drilling, though the M18 did a bit better than both in our harder drilling tests.

Drilling

This drill earned our approval based on its performance at drilling into a solid core door with a 5" hole saw, drilling through steel sheets with twist drills, and drilling through some dimensional lumber with a 1" paddle bit.

The DCD771C2 did decently well with the 5" hole saw, drilling to the full depth of the saw with no issue. It drilled the hole nice and smooth, not even stalling as it got close to the full depth. It took about three times longer than the top-performing drills to reach this depth, but it was still less than a minute.

With the 1" paddle bit, the DCD771C2 did particularly well. It can drill through the 2x12 in its higher gear the vast majority of the time, only requiring us to downshift if we were drilling through a knot or other particularly difficult bit. It offers you a ton of control, but we could tell that it did have slightly less power than the best drills, though this was barely discernible.

The DCD771C2 did well drilling through the steel sheets, never struggling or stalling. It took 2.4 seconds to get through the 16-gauge sheet metal with the ¼" drill and 7-9 seconds to make it through with the ½" drill. However, it did bind up a bit with the ½" drill right as it punched through, requiring us to drop it down to the lower gear.

Driving

The DCD771C2 earned a fantastic score in our driving category, based on its performance at driving in both a countersunk #9 wood screw and a 5" long, ½" diameter lag screw.

This cordless drill is phenomenal when driving in the normal wood screws. It set the screws very quickly with tons of power and had absolutely no problem setting the screw heads flush. The DeWalt DCD771C2 offers tons of control, letting you set the screw head to the perfect depth.

Battery Life

We tested this model with a 1.3 Ah battery in the package we purchased. To evaluate and compare the battery life of each tool head-to-head, we used each drill to drive in 16 normal wood screws and then drill three holes with the 1" paddle bit, repeating this until the drill's battery died. Points were awarded based on the total number of cycles accomplished. The DCD771C2 has a 1.3 Ah battery, which only made it through four full cycles of this, dying after driving in the first two screws of the fifth. For comparison, the best drills did over ten cycles, but most of those had a 1.5 Ah or 2 Ah battery.

The DCD771C2 redeemed itself a bit by including two batteries, so you can at least always have one on the charger while you are working and by charging faster than average. It takes less than an hour — 58 minutes — for the included charger to completely recharge a dead battery.

Convenience

It's super easy to swap batteries on this drill, with an easy-to-release locking button, and the battery slides in and out effortlessly. However, this drill lacks a battery meter, so you don't have a concrete way of knowing how much battery life you have remaining. The DCD771C2 is about the average weight for these products — just shy of 3.5 lbs with the battery installed.

It has two different gear ratios, with rpm ranges of 0-450 or 0-1800. The chuck can expand to up to ½", but we were a little bummed out that this drill did not include a belt clip, though one can be equipped if purchased separately.

The DCD771C2 also has a built-in work light above the trigger. It provides decent illumination of whatever you are working on and stays on for about 20 seconds after you let go of the trigger — a feature we found to be incredibly useful in a DIY tool.

Should You Buy the Dewalt DCD771C2?

The DCD771C2 is another exceptional drill that gets the job done, even if it can't quite match the overall performance of the top tools. We found that it offered an unparalleled amount of control and power when driving in screws, though we wish it had a bit longer battery life. This drill can handle almost every task you throw at it — though it might take a little longer than the top-tier tools. This drill isn't a fantastic value, as it has a somewhat higher list price, but we found it offered at significant discounts on sale, making it a much more attractive bargain buy.
