DeWalt DCN660B: precision depth control for perfect trim work
The DeWalt DCN660B earned its top spot through depth control precision. The tool-free depth wheel adjusts in fine increments, and the brushless motor maintains consistent driving energy from the first nail to the last on a charge. In our 50-nail test, depth variation was 0.2mm -- less than the thickness of a business card. Surface marking was minimal; the molded nose contact area distributes pressure evenly without leaving sharp imprints.

Milwaukee M18 2741-21CT: best 15-gauge for hardwood trim
For hardwood flooring transitions, thick oak baseboard, and solid wood cabinetry, the Milwaukee 15-gauge finish nailer provides better holding power than 16-gauge alternatives. The angled magazine fits into corners more easily than straight-magazine designs. Driving power from the M18 brushless motor is excellent in hardwood without pre-drilling. The included rafter hook and belt clip make it convenient on active job sites.
What matters most
Gauge selection
16-gauge for most trim work; 15-gauge for thicker trim and hardwood where holding strength matters more than hole size.
Depth adjustment
Tool-free micro-adjust depth control is essential for consistent results. Fixed depth nailers require testing and adjusting on scrap for every wood species change.
Dry-fire lockout
Prevents damage to work surfaces and splits in trim when the magazine runs dry during rapid sequential firing.
Magazine capacity
100-strip capacity reduces reload frequency. Check that the magazine loads quickly from any angle.
Battery compatibility
For a jobsite tool, shared battery platform with your drill, circular saw, and other tools is the single biggest value multiplier.
Frequently asked
15-gauge nails are slightly thicker and hold better in hardwoods and thicker trim. 16-gauge nails leave smaller holes and cause less splitting in thin trim and MDF. 16-gauge is the more versatile choice for general finish work.
For most residential finish carpentry, yes. Modern brushless cordless nailers match pneumatic for driving consistency without a compressor, hose, or power outlet requirement.
A 2Ah 20V battery typically drives 700-900 nails before needing a recharge -- enough for most trim, molding, and cabinetry jobs.
Over-driving is the most common cause. Adjust depth until the nail head sits flush or just below the surface. Nose plate contact marks can be reduced with a rubber nose tip protector.
