The short answer
For most trim work, the Milwaukee M18 Fuel 16-Gauge Nailer drives nails more consistently, especially when the battery is partly discharged or the work pace is high. Its firing behavior is predictable, depth adjustment is easy to repeat, and it recovers quickly between shots.
The Metabo HPT NT1865DM is not a bad second choice. It is often less expensive as a kit, has a slimmer nose, and can be a very good value for occasional baseboard, casing, and small woodworking jobs. However, it is more sensitive to battery condition and setup. If your priority is the fewest proud heads, misfires, or pauses during a full day of installation, Milwaukee has the edge.

What “drives consistently” means here
A finish nailer can fire every time and still produce inconsistent results. The useful test is whether it seats 16-gauge nails to nearly the same depth across hardwood, pine, and engineered trim without repeated adjustment.
There are four failure modes worth watching:
- Proud heads: the nail stops above the surface and needs to be set manually.
- Overdriving: the head sinks too far, leaving a crater that may show through paint.
- Dry firing or misfires: the tool cycles without driving a nail, or fails to fire because the nail strip is not positioned correctly.
- Slow recovery: the tool fires one shot correctly but hesitates when you bump-fire several nails in succession.
Both nailers use a brushless motor and a spring-drive mechanism rather than compressed air. That removes hoses and compressors, but it also makes battery voltage, cold temperatures, and fast shooting more noticeable.

Check the exact package before buying. Batteries, chargers, and included accessories vary, and some listings use the bare-tool model number while others sell a kit.
How the Milwaukee drives
The Milwaukee’s main advantage is its consistency during repeated shots. In pine casing and baseboard, it generally leaves a clean, small entry mark and seats the nail head close to flush without much tuning. On harder trim, such as oak, it has enough reserve power to avoid turning every other nail into a hand-finished repair.
The depth wheel has a useful range, but it is still possible to overdrive nails if the setting is too aggressive. Start with the wheel near the middle, test three nails on a scrap of the actual trim, and adjust in small steps. A change of only a click or two can be visible in soft pine.
Milwaukee’s contact mode is practical for long runs of baseboard, but sequential mode is better around exposed corners and narrow casing. The tool is not especially light with a large M18 battery. A compact battery reduces fatigue, while a 5.0Ah pack gives more shots and generally maintains stronger performance late in the charge.
For a contractor or serious remodeler, the Milwaukee M18 16-gauge nailer makes the most sense when consistent output matters more than the lowest purchase price.
How the Metabo HPT drives
The NT1865DM is capable of clean work, particularly with 1-1/4- to 2-1/2-inch nails in softwood trim. Its nose is relatively easy to place in tight corners, and the tool balances well enough for normal room-by-room installation. It also accepts the company’s MultiVolt batteries, which can be useful if you already own that platform.
Its weak point is not basic driving power; it is maintaining the same feel as conditions change. With a partially discharged battery, cold battery, or rapid bump firing, you may see more variation in nail depth. That does not mean every shot fails, but the depth wheel may need a small correction sooner than it would on the Milwaukee.
There are also occasional dry-fire symptoms when the magazine is nearly empty. Keep the nail strip seated firmly and do not assume the tool is jammed before checking the reload position. As with any cordless finish nailer, a bent nail or damaged collated strip can create a stoppage that looks like a power problem.
If you only install trim a few times a year, the Metabo HPT NT1865DM is often the better value, especially when sold with a battery and charger.
Battery, nails, and maintenance matter
Use the same nail brand and length while comparing the tools. Collation quality varies, and a damaged strip can cause feeding problems in either nailer. Do not mix up 15-gauge and 16-gauge nails; the strips are not interchangeable even when the lengths look similar.
For consistent depth, charge the battery before starting a large job and let a cold pack warm indoors. Keep the magazine free of adhesive dust and remove jammed nails with the tool switched off and the battery removed. Neither nailer needs compressor oil, but both benefit from periodic cleaning around the driver channel and contact nose.
Which one should you buy?
Choose the Milwaukee if you install several rooms of trim, work in hardwood regularly, already own M18 batteries, or want the more predictable tool under fast production conditions. Its extra cost is easier to justify when rework costs more than the price difference.
Choose the Metabo HPT if the nailer will see occasional weekend use, you already have compatible batteries, or the kit price is substantially lower. It can produce professional results when you test the depth on scrap and work at a controlled pace.
For either tool, use sequential firing for visible trim, test on a cutoff, and leave enough material behind the nail to avoid splitting. A consistent setup does more for the final finish than switching between two otherwise competent cordless nailers.
