Start with the nail your trim requires
For suitable general trim with air: Metabo HPT NT65M2S
Compare the NT65M2S first when your project calls for straight 16-gauge finish nails and you already own a suitable compressor. Its lighter pneumatic body and adjustable driving depth make it a practical general-trim starting point.
Choose the angled 15-gauge NT65MA4 for a project requiring that fastener format. If hose-free operation matters and you own 20V MAX batteries, compare the angled 16-gauge DeWalt DCN660B. A finish nailer is a task-specific purchase: none of these replaces a brad, framing or roofing nailer.
The best finish nailer starts with the assembly you are fastening. Nail gauge, length, collation and magazine angle must match the tool and material. Choosing only by power source can leave you with a nailer that takes the wrong strips or makes an unnecessarily large hole.
This guide compares three established, documented choices for US trim and woodworking.
Our analysis is based on manufacturer specifications and project fit. We have not run a drive-depth, jam-rate or runtime test. Check the exact tool instructions, material requirements and your fastening plan before choosing a model.

Choose the fastening format, then the tool
1. Metabo HPT NT65M2S — Straight 16-gauge pneumatic starting point
The NT65M2S is our first comparison for appropriate general trim work when you already have a suitable air system. Metabo HPT documents a straight 16-gauge magazine, 1 to 2-1/2-inch nail range, depth adjustment and a 3.7-pound tool weight. Its air duster and adjustable exhaust are additional conveniences rather than reasons to ignore the fastening specification.
The useful buying case is a relatively light tool separated from the compressor. That can suit a sequence of molding, casing or cabinetry tasks, provided the specified nails and fastening method suit the assembly. A pneumatic tool still brings a hose into the room and requires correct pressure and air supply; the nailer alone is not a working kit.
Choose it when straight 16-gauge nails match the project, rather than because they are advertised as universally versatile. Check magazine clearance at the actual corner and plan the hose route. We have not measured drive consistency or compared the three tools on hardwood trim.
Worth considering: 1 to 2-1/2-inch straight finish nails; depth dial.
Before you buy: Compatible compressor and hose required.
2. Metabo HPT NT65MA4 — Angled 15-gauge pneumatic alternative
The NT65MA4 changes both the fastener and magazine arrangement. Its maker specifies 15-gauge angled nails, a 34-degree magazine, depth adjustment and a 4.2-pound tool weight. Compare it for an assembly calling for that approved nail format and when the angled magazine improves permitted access.
A lower gauge number describes a thicker nail, not an automatic better finish. That can bring a different hole to fill and a different splitting concern in thin trim. Select it from the material and fastening requirements rather than assuming a heavier fastener is always useful. The manufacturer lists crown, base molding, casing and related trim applications, but the actual assembly still controls nail selection.
Its air duster does not replace required cleanup or protective equipment. Budget for a suitable compressor, hose and exact approved nails. Do not put straight 16-gauge strips into this 15-gauge angled magazine.
Worth considering: 34-degree magazine; 1-1/4 to 2-1/2-inch 15-gauge nails.
Before you buy: Different nail format; larger visible fastening hole.
3. DeWalt DCN660B — Cordless angled 16-gauge alternative
The DCN660B is worth comparing when a hose would make scattered trim jobs inconvenient and you already own compatible DeWalt 20V MAX batteries. It uses 16-gauge angled nails in the documented 1-1/4 to 2-1/2-inch range. DeWalt lists depth adjustment, tool-free jam release, a stall-release lever and diagnostic/work LEDs.
You carry the power source on the tool and avoid setting up an air hose or compressor. That can make a few appropriately specified repairs simpler, but it changes the working weight and battery-management decision. The B package excludes the battery and charger.
This is the angled DCN660B, not the straight-magazine DCN662B or newer DCN220B. Its nails are not interchangeable merely because all three have a 16-gauge description. Confirm the manufacturer nail specification and check the current seller, condition and warranty terms.
Worth considering: Battery-powered brushless design; 1-1/4 to 2-1/2-inch angled nails.
Before you buy: Tool only; battery and charger separate; angled nails required.
Finish nailer buying guide
15 gauge, 16 gauge and brads are different choices
Lower gauge numbers describe thicker nails. A 15-gauge finish nail and a 16-gauge finish nail therefore create different holes and have different approved uses. An 18-gauge brad is another fastener format, often considered where a smaller hole is desirable.
Do not decide from gauge alone. The material, joint, trim dimensions and fastening requirements determine what belongs in the assembly. Verify the specification for the work rather than applying a generic “stronger is better” rule to delicate molding.
Check straight versus angled collation
Gauge and length do not fully identify compatibility. The tool may require a particular magazine angle, head design and collation format. Read the nail selection section of its manual and buy only the approved strips.
An angled magazine can change access around corners; it does not establish a universal better tool or authorize firing at an unsafe angle. Measure clearance with the tool held as instructed. Straight and angled 16-gauge nailers should not be treated as taking the same strips.
Compare the complete air or battery system
A pneumatic purchase includes an appropriate air supply, regulator, hose and fittings, even when you already own some of them. Check the manual’s pressure and air requirements. Plan a route that keeps the hose clear of feet and finished surfaces.
For cordless, include a compatible approved battery and charger. Do not compare a bare cordless tool with a complete pneumatic kit as though both arrive ready for the same job.
Choose depth from a test piece
Adjustable depth is useful because material density and the fastening setup can change how the nail seats. Prepare a matching scrap or suitable test piece and follow the tool instructions for the setting. Assess the result before fastening visible finished trim.
Overdriving can damage the surface; leaving the head proud creates a different finishing problem. Avoid trying to compensate for an unsuitable nail or tool by increasing air pressure outside the approved range. The fastening requirement still comes first.
Setup, maintenance and jam management
Use the instructed trigger system and protective equipment
Read the tool manual and obtain appropriate training before use. NIOSH recommends full sequential triggers to reduce unintended firing risk. Select and use the applicable mode as instructed; faster contact firing is not a reason to bypass safer placement procedures.
Keep hands and other people clear of the potential nail path. Inspect what lies behind the work, and follow the required protective-equipment and workholding instructions. Do not bypass a contact tip or other safety device.
Disconnect before loading, clearing or servicing as instructed
Follow the exact loading and isolation procedure. Remove the battery or disconnect the air supply when required before adjustments, jam clearing or servicing. A tool-free jam latch does not make it safe to open a powered, loaded tool.
Keep the nose pointed safely and follow the manual’s sequence for removing fasteners and a jam. Do not force a damaged driver or continue with a malfunctioning contact mechanism. Have faulty equipment serviced through the approved route.
Keep fasteners and the tool clean
Store nails in suitable dry conditions and reject damaged or unsuitable strips. Clean the magazine and accessible areas by the manufacturer’s method. Use only the specified lubrication schedule; do not assume all pneumatic or battery nailers need the same oil.
Inspect hose connections, battery condition, nose pad and fasteners before use. Keep the case and supplies organized by gauge and collation so a visually similar strip cannot be loaded by mistake.
Finish nailer FAQs
Which finish nailer is recommended first?
The NT65M2S for appropriate straight 16-gauge trim when you have a suitable air setup.
Can I use 16-gauge nails in a 15-gauge nailer?
No. Use only the exact fastener formats approved in the tool’s nail-selection instructions. Gauge, length and collation all matter.
Is an angled magazine always better?
No. It offers a different access arrangement and nail format. Choose from the assembly, required clearance and safe operating method.
Does the DCN660B include a battery?
The selected B offer is the tool-only model. Check the actual seller’s contents; battery and charger are separate unless an expressly identified bundle includes them.
Can these replace a framing nailer?
No. These are finish nailers with specific approved fasteners and applications. Use the appropriate tool and specified fastening method for structural work.
A useful finish nailer fits your fastening plan
For suitable straight 16-gauge work with an air system, compare the NT65M2S. For a specified angled 15-gauge application, compare the NT65MA4. For compatible angled 16-gauge work without a hose, the DCN660B is the battery-platform alternative.
Confirm nails, tool format and complete power setup before buying.
