The Metabo HPT 36V MultiVolt Cordless Metal Connector Nailer is designed to increase productivity on the residential framing job site by eliminating the need to navigate long hoses around the job site. When Metabo HPT reached out to us for a review the timing could not have been more perfect. We were just starting a deck build and would be hanging our joists just in time.

Every year a couple of crew members joke around and talk about a tool of the year.  A tool that helped you the most, saved the most time, and was worth the investment! With COVID last year, our crew built 4 decks in 6 months. Last year our tool of the year was the pneumatic metal connector from Metabo 1-1/2″ Pneumatic Metal Connector Nailer. Prior to that, we used to hand bang our metal connecting nails and when the area was tight we palm nailed them.

Now given the chance to use the Metabo NR3665DA cordless nailer we were excited to get it out on the job site and compare it to the pneumatic nailer we thought was last year’s Tool of the Year! Editor Rob Robillard thinks the Metabo 36v Cordless Router could be the winner of the Tool of the Year. Let’s take a closer look at the Metabo HPT NR3665DA

Will Weight be an Issue?

As we mentioned earlier this nailer arrived the day before we were set to hang out joists on our current deck build. The first thing we noticed when using was the weight. Weighing in at almost 11lbs we were skeptical on how long it was going to take us to become fatigued shooting 40 hangers, 20 hurricane ties, and 4 angle brackets. That’s almost 500 nails being shot, some at some awkward angle but the NR3665DA did not disappoint, misfire, or create as much fatigue as we anticipated.  It’s heavy, to say the least, but that being said it beats dealing with the hose and compressor! Weighing more than double the pneumatic nailer sometimes cutting the hose is worth the extra weight.


Strap-Tite Probe Tip

The Strap-Tite Probe Tip helps you to put each nail precisely, saving you money and time. This cordless Metal Connector nailer can drive 1-1/2″ and 2-1/2″ nails up to 0.162″ in diameter all day thanks to Metabo HPT’s patented Air Spring Drive System, which simulates the feel of a pneumatic nailer, and the power of the MultiVolt 36V battery. With the bundled 2.5 Ah MultiVolt 36V battery, Metabo claims to get 900 2-1/2″ x 1.162″ nails per charge.

On-Site Performance

This nailer is a workhorse on the construction site. This nailer does not include a flywheel, which eliminates the need to wind up the flywheel before shooting the nails. This saves time and eliminates the need to wait! Because it’s part of Metabo’s 36v Multi-volt series, you can use their MultiVolt AC adaptor with it. While not standard practice in the field for a metal connection nailer, we felt it could be useful at the end of the day when the battery runs out. The Metabo HPT NR3665DA gets an A+ for removing the hose and compressor while still providing the power of a pneumatic nailer.

Overall Thoughts

At the moment, there isn’t much of a cordless choice for metal connection nailers. With their 36v NR3665DA, Metabo HPT has set the standard extremely high. Metabo is always striving to improve its products. The gun’s only drawback is that it is significantly heavier than air. The Tool Box Buzz crew is quite impressed with this nailer and highly recommends it if metal connection nailing is something you do on a regular basis.
