DeWALT 20V MAX Brushless Drywall Screwgun Review

The wait is over if you're looking for a light, compact, powerful alternative to corded dywall screwgun.

DeWALT 20V MAX Brushless Drywall Screwgun

DeWALT 20V MAX Brushless Drywall Screwgun



Contractors and renovators have been waiting for a reliable alternative to the corded drywall screwgun for quite some time. With the arrival of the DeWALT DCF620 it appears the wait is finally over. The DCF620 has just about everything that you'd want in a dependable drywall gun – it's light, compact, powerful, and can be used with an optional collated magazine auto-feed attachment.

The DCF620 is available as a bare tool (DCF620B) for those with a plethora of DeWALT batteries, or in one of two kits that come with a carry case, charger, and either two compact 2.0 Ah batteries (kit DCF620D2) or two premium 4.0 Ah batteries (kit DCF620M2). 

With battery installed, the DCF620 is comparable in weight to a corded drywall gun. Even with the larger premium 4.0 Ah batter installed, it only weighs 3.8 pounds. As well as being light in weight, I find the DCF620 to be well-balanced and comfortable to hold – important considerations if you'll be driving thousands of screws per day, and a lot of them overhead. I find that the handle design helps to keep the tool from shifting in my hand during use.

Typical DeWALT brushless motor

The DCF620B has a brushless motor, which helps reduce overall tool weight, but, more importantly, is more efficient at consuming and delivering battery power. They use electronic speed controllers that provide increased control over motor speeds; they produce less friction, heat, and amp draw so they make more efficient use of energy; they're virtually maintenance free; and they have a longer service life. Which makes them a better all round choice. For more information read our short Introduction to Brushless Motors

Locking-on the trigger takes two hands

The DCF620 has a variable speed trigger that provides a smoother start when using the tool. The lock-on button is located just below the trigger, and it's all but impossible to manipulate the button single-handed while simultaneously depressing the speed trigger. Of course, it's only an inconvenience if you regularly use the lock-on feature. With a corded screwgun I like to run the gun full-speed with the trigger locked-in. It's easier, and quicker. However, doing this with the DCF620 may consume more battery power than pulsing the trigger to set screws.

The DCF620 is equipped with a depth sensitive clutch. With the variable speed trigger depressed, the driver bit doesn't turn until it encounters resistance. Once the screw is seated, the clutch automatically engages, which stops the driver bit from turning.

Quick and easy screw depth adjustment

One of the most crucial features on any drywall gun is how quickly and accurately you can adjust screw depth. Too deep and the screw won't do it's job; not deep enough and there'll be problems for the home owner down the road. While setting screws correctly takes skill and experience, along with using the right length of screw for the job, you need to be able to adjust screw depth on the fly.

On the DCF620 you can set screw depth very quickly and precisely with a quick twist of the adjustment collar, located on the nose cone. The key to getting consistently good results when driving screws is to
 push firmly and in-line with the bit, letting the clutch do it's job. Once you've set the right depth you'll invariably get consistent results - unless you hit a knot that is.

Twist the collar to remove the nose cone

Removing the nose – simply by twisting the retaining collar to the right – provides you with access to the driver bit, which is attached to a removable bit holder. I really like the long skinny nose cone, as it enables a great line-of-sight when installing screws, and it's easier to get into tight corners.

Removing the bit holder

The bit holder retracts easily, but you'll definitely need to use pliers to extract the driver bit. While virtually all drywall screws use a #2 Phillips driver bit, you can install other driver bits in the bit holder, for example when you want to use the screwgun for installing decking or fencing with Robertson screws.

Angled LED work light for low-light situations

There's an LED work light on the base of the gun that provides excellent lighting around the nose area – handy if you happen to be working in low-light situations. The belt hook is a decent size, and enables you to hang the screwgun handily at your side. You can move the hook to either side of the tool.

Collated screw strip

A lot of drywallers find that using collated screws increases productivity. Even though collated screws cost more than boxed screws you can sink more of them in the same amount of time as feeding the screws manually. DeWALT sells a Collated Magazine Attachment (DCF6201) for the DCF620 that takes 1" to 2" screws.

Adjusting the auto feeder for screw length

There is a detent pin slot on the side of the magazine that enables you to set the feeder for the length of screw you'll be using. You can use all the popular screw strips with the DCF6201, including the popular Senco Duraspin strips.

Auto feeder snaps onto the screwgun

To attach the feeder to the DCF620 remove its nose piece and the drive bit holder, install the 6" Phillips bit that comes with the DCF6201, and then snap the feeder onto the end of the screwgun.

Adjusting screw depth on the auto feeder

You'll adjust screw depth via a dial on the side of the auto feeder.

Auto feeder installed

The auto feeder adds about 1 pound to the weight of the screwgun, and offsets the center of gravity towards the front of the end of the gun. For the few times I tried the auto feeder the feeding mechanism never stuck. Loading the nail strip is quick and easy.

According to DeWALT, you should be able to hang up to 45 sheets with a single charge of the 2.0Ah battery, and up to 58 sheets with the 4.00Ah battery. At about 1-1/2 screws per square foot, that's the equivalent of 2,160 and 2,780 screws respectively. With a couple of batteries on the go you can install drywall all day long without missing a beat.

Light weight, compact,and powerful alternative to a corded dywall screwgun

This drywall screwgun isn't just for professional drywallers. Renovators and avid DIYers will like the tool just as much. It's a real time saver for installing drywall and other sheet goods. However, you can also use the DCF620 to install sheathing, subflooring, lay decking, or put up fencing.
