The air compressor probably the most annoying part for many finish carpenters to do their nailing job. Lugging the compressor in, untie air hose, searching power, oiling nailer, and striving to avoid tripping over the hose as they pull it around all day. Not to mention the racket, because it  kicks on randomly and scares the crap out of everyone around. However, the battery-powered nail gun can be the best alternative to avoid air hose and noisy compressors. In our recent research, we found that DeWalt DCN660B is one of the best cordless battery powered finish nailers in the market. It's a 16 Gauge Angled Finish Nailer and can drive 16 Gauge angled finish nails from 1-1/4" to 2-1/2". It's ideal for fastening crown molding, door & window casings, and baseboards.

DeWalt DCN660B is the improved version of DeWalt’s popular 16 Gauge cordless nailer model DeWalt DC618K XRP, and the design is apparently similar to DeWalt's another popular cordless framing nailer model DCN692M1. The key difference of this model is an efficient use and brushless motor. Brushless technology makes it more reliable, more powerful, and lighter. It's compact and nearly 2-1/2 pounds lighter than its preceder. The total weight is just 6 pounds with battery.

DeWalt DCN660B is compatible with all Dewalt 20v max lithium-ion batteries, and 2.0 Ah battery pack is also an option to powering the tool. You can expect to shoot 800 nails per charge using the compact battery. It also claims that you can drive up to 2,200 nails from a single charge using DeWalt 20V premium XR 5.0Ah lithium-ion battery pack, which they sell separately.

DeWalt Wants You to be Tool-Free

It's frustrating to have a tool out of commission, and with that in mind, DeWalt's engineers strive to make DCN660B as user-friendly as possible by reducing downtime. The nailer is easy to load, just place a strip of nails in the rear slot and pull back the follower until it catches. If any of these nails get jammed, it won't be a big deal. A tool-free jam release mechanism and an integrated tool-free stall release lever allow you to easily clear nail jams and resets the driver blade without using any additional tools.

DeWalt DCN660B also comes with a tool-free selectable trigger system feature. You can now easily change the firing/actuation mode from sequential to bump or bump to sequential by simply sliding the selector switch. There is a knob near the tip that allows quick, easy, and tool-free depth adjustment. The depth indicator will help you to effortlessly dial in the accurate depth for frequently-used nail/trim combinations.

DeWalt DCN660B 20V 16 Gauge 20° Cordless Finish Nailer comes with high tech multi-functional LED lights and an adjustable belt hook. The LED light not only notify you of the battery charging status (and send an audible alert if it has stalled) but also helps you to install trim in dark and scary corners. If you notice left light blinks four times, it's time to recharge your battery. Continuous flashing right light indicates you've got a jammed fastener. If you see both lights are on, motor runs but failed to launch, it's time to repair. The removable or retractable belt hook lets you hang your tool on a nail or other suitable hanging spots.

DeWalt DCN660B is overmold with a fair amount of rubber placed on its body in a planned way. As a result, it's become more comfortable to use while securing the trim and the area you are working in. A no-mar pad is included, and it helps keep your work surface tidy. The trigger locking mechanism will prevent unintended nail firing and keep you safe from any serious injury.
