Milwaukee M12 Cordless 23 Gauge Pin Nailer 2540-21

One interesting feature on the trigger that you may not know is that the M12 pinner has an electronic time-out on the secondary trigger. If the trigger is held down for more than 40-seconds and NOT fired the tool will shut off and you will need to recycle the trigger to activate it.

I think this is a great feature but the time should be reduced to 20 seconds.

Nice Features Not Easily Noticed:

If you look too quickly you’ll miss some nice features on this pinner.

Magazine Magnet

When loading the pins into the magazine if you look close you’ll notice a small magnet. Missed by many, this magnet is your third hand when reloading or changing pin sizes.

Tapered Tank Design

Looking at the top of the tool you’ll see that the nitrogen tank tapers, back toward the front. This keeps the business end of the tool narrower and more compact, allowing better maneuverability, something we appreciate in a finishing tool.

Non-Marring Tips

Another nice feature is the non-mar contact tips. The reserve tip is clipped on the rear of the magazine. If you look closely at it you’ll notice it is a “half” tip. The half tip takes an already nicely designed front end of the tool and makes the tip area more visible. The half-tip is for the carpenters that argue that the tip blocks their line of sight of the feed-lips. [the area where striker and pin feed-thru tool]

Depth of Drive

The M12 pin nailer has a tool-free depth of drive knob. This is something that I immediately noticed and appreciated since all of my pneumatic pinners needed an Allen wrench to move the nose back and forth. The depth knob is faster to dial in and obviously way easier.

Dryfire Lockout
The M12 pin nailer has a magazine reload indicator which I never seem to notice or look at. It does have a dry-fire lockout which is useful for prevent unnecessary holes in our workpieces.
Gas Tank - Power

The pin nailer, and all of our Nitrogen Gas Spring Nailers, work very similarly.

The cylinder has two parts that make up the tank: an inner cylinder and an outer cylinder. The space between those two cylinders is the area that is filled with Nitrogen. The striker & piston travel within the inner cylinder, using the pressure in the tank to provide driving power for the fastener. Each style of nailer (23GA, 18GA, Framing Nailers, etc.) are filled to different PSI’s.

There are two reasons we use nitrogen instead of compressed air, and limiting condensation is one of them.

1) when we fill the tools, during manufacturing or service, we pull a vacuum so the tank is completely cleared. We then fill them with 99.9% nitrogen so there’s essentially no condensation in it. We could do this with air using a compressor that separates condensation/moisture out of the air, but it’s easier and more effective & repeatable to do this with pure 99.9% nitrogen

2) second reason we use nitrogen is to limit any seal permeation. Any sealed, pressurized vessel will experience some small level of permeation through the seals over time. Nitrogen permeates much slower than air. By using nitrogen we can keep permeation so minute that it would be many years (if ever) that a user/owner would ever experience degraded performance due to permeation
ThxThis pin nailer, comes with a 3-year warranty and was designed to provide a user 3-4 years of heavy use without the need for service. That should equate to 50 to 70k barads installed.
Runtime
Runtime: This pin nailer can fire up to 750 pin nails, per charge, when equipped with a 1.5 Ah battery.
LED Light
In the past, I’d scoff at the idea of light on a nailer, especially a pinner. After using this on a project with mediocre lighting, I actually have to eat crow and admit that I really like this feature.

Using the Milwaukee M12 23 Gauge Pin Nailer
I used the M12 pin nailer in the shop building a cabinet to cover a stove hood and also on a cabinet crown molding installation project.
Besides the fact that this pinner is cordless and eliminates the hose, there are three things I like about this pin nailer:
1. Well-Designed: items like the depth or drive, magazine magnet, LED light show thought and care went into this design. They look at this tool, innovated it, and tried to eliminate pain points for the user.

2. Precision: It’s accurate! The double-action trigger and non-marring precision point tip provide sequential driving and accurate pin placement, with a great line of sight.

3. Performance: When I think of performance I’m thinking of size, weight, and power. The M12 pinner is pretty close to my pneumatic nailer in size and punches pins into hardwood like nobody’s business.
