Best Brad Nailers for Interior Trim
An 18 gauge brad nailer is the right tool for most interior trim. It drives thin brads that leave a small hole, so baseboards, casing, crown molding, and shoe molding can be fastened without splitting thin trim and without large holes to fill. This guide compares five 18 gauge brad nailers, four cordless models and one pneumatic model, so you can match the tool to the trim you install and to the batteries or compressor you already own.
Direct answer. The DeWalt DCN680B is our top pick for most interior trim work. It drives brads up to 2-1/8 in, runs on the large DeWalt 20V MAX platform, and needs no compressor or hose. For the lightest tool and the lowest running cost per nail, the pneumatic Metabo HPT NT50AE2 at 2.2 lbs is the best pick if you already own a compressor. For the lowest entry cost, the Ryobi P320 is the budget pick for occasional trim jobs.

How we research
We compared specs, maker data, and owner review themes for 5 brad nailer models, all 18 gauge and all suited to interior trim. We checked each model against its maker page or maker document on 2026-11-06 and recorded only specs the maker source itself states. Where a maker page did not list a spec, such as magazine capacity or weight, we left that spec out rather than filling it in from a retailer listing. Amazon product pages could not be confirmed for this batch because amazon.com showed Access restricted to AI agents on 2026-11-06, so no Amazon check was attempted. 5 products could not be confirmed and ASIN_TBD is shown. Our criteria were nail length range and magazine capacity at 30 percent, cordless or pneumatic fit for finished rooms at 25 percent, weight and handling at 20 percent, depth control and dry-fire protection at 15 percent, and battery platform or compressor needs at 10 percent. Two notes on maker coverage: the Ryobi P320 did not appear in a ryobitools.com search on 2026-11-06, so its specs here come from the Ryobi instruction manual for the P320, and the Makita XNB01Z maker product page did not surface in a makitatools.com search on 2026-11-06, so its specs here come from the Makita maker description for the XNB01Z. No maker price was verified on any maker page we opened, so no maker price is shown in this guide. Safety guidance in this guide comes from the maker manuals, which readers should read in full before first use.
DeWalt 20V MAX XR 18ga Cordless Brad Nailer (Tool Only) DCN680B
Best for most interior trim work, from baseboards and casing to crown molding and shoe molding.
Key specs are 20V MAX XR, with a nominal voltage of 18V, and 18 gauge fasteners from 5/8 in to 2-1/8 in. It has a brushless motor powered by a DeWalt 20V MAX lithium-ion battery. It is sold as a tool only, with no battery or charger included. The maker page describes it as ideal for fastening decorative molding, casing, kitchen crown, and shoe molding, and as ready to work without gas, a compressor, and a hose.
Pros:
- Longest nail range in this set at 2-1/8 in, which covers thicker casing, crown molding, and shoe molding.
- Brushless motor and cordless design remove the compressor and hose from a finished room.
- Sits on the large DeWalt 20V MAX battery platform, so owners of other DeWalt 20V MAX tools can share batteries.
Con: Sold as a tool only, so a buyer without a DeWalt 20V MAX battery and charger must buy them separately, and the maker page we opened did not list magazine capacity or weight.
Owner review themes point to owners who praise the cordless freedom, the clean nail holes in trim, and the way it handles crown and casing without dragging a hose through a finished room. The recurring complaints are the cost of buying into the tool only format without a battery, and the weight and balance of a cordless nailer compared with a light pneumatic model.

Check current price on AmazonMilwaukee M18 FUEL 18ga Brad Nailer (Tool Only) 2746-20
Best for long runs of trim and for hardwood casing where consistent depth matters.
Key specs are M18 FUEL, 18 gauge, with nail sizes from 5/8 in to 2-1/8 in and a magazine capacity of 110 nails. The maker source states up to 1500 nails per charge on a REDLITHIUM 2.0 Compact Battery. It has sequential and contact actuation modes, dry-fire lockout, an LED work light, and a POWERSTATE brushless motor. It is sold as a bare tool, and the maker source also lists it as available as kit 2746-21CT with a battery, charger, and bag.
Pros:
- Longest nail range in this set at 2-1/8 in, with a 110 nail magazine that cuts reloading on long runs of casing.
- Dry-fire lockout and LED work light are stated on the maker source, which helps protect trim from blank firing in low light.
- Nitrogen air spring design fires with zero ramp-up time, so there is no spin-up pause before each nail.
Con: Sold as a bare tool, so a buyer without Milwaukee M18 batteries must buy a battery and charger separately, and it is the premium priced pick in this set in owner discussion.
Owner review themes point to owners who praise the instant firing with no ramp-up, the consistent depth in hardwoods and softwoods, and the clean nail holes. The recurring complaints are the high tool only price, the weight of a cordless nailer on overhead crown work, and the need to watch the magazine near empty even with a dry-fire lockout.

Check current price on AmazonRyobi 18V ONE+ AirStrike 18ga Cordless Brad Nailer P320
Best for budget conscious homeowners doing occasional trim jobs who already own Ryobi 18V ONE+ batteries.
Key specs are 18V ONE+, 18 gauge, with brad nails from 5/8 in to 2 in. It uses AirStrike technology, so it needs no compressor, hose, or gas cartridge. It is sold as a tool only, with battery and charger sold separately. Note that the P320 did not appear in a ryobitools.com search on 2026-11-06, so the specs in this section come from the Ryobi instruction manual for the P320 rather than a live Ryobi product page.
Pros:
- Lowest cost way into a cordless brad nailer in this set, and it runs on the large Ryobi 18V ONE+ battery system.
- AirStrike design removes the compressor, hose, and gas cartridge from trim work in a finished room.
- Simple cordless setup suits occasional trim jobs such as baseboards, shoe molding, and window casing.
Con: Shorter maximum nail length at 2 in than the DeWalt and Milwaukee picks, and the P320 did not appear in a ryobitools.com search on 2026-11-06, so its maker page specs could not be checked directly.
Owner review themes point to owners who praise the low price, the simple cordless setup, and the shared ONE+ batteries for home and yard tools. The recurring complaints are a short delay between trigger pull and firing compared with pneumatic nailers, occasional trouble with the shortest 5/8 in brads, and the weight of the tool with a larger battery fitted.

Check current price on AmazonMakita 18V LXT Lithium-Ion Cordless 2 in Brad Nailer (Tool Only) XNB01Z
Best for large trim jobs by owners already on the Makita 18V LXT battery system.
Key specs are 18V LXT lithium-ion, 18 gauge, with brad nails from 5/8 in to 2 in and a magazine capacity of up to 110 nails. The maker description states up to 1000 nails on a single charge with an 18V LXT 3.0Ah battery. It is sold as a tool only, with battery and charger not included. Note that the XNB01Z maker product page did not surface in a makitatools.com search on 2026-11-06, so the specs in this section come from the Makita maker description for the XNB01Z rather than a live Makita product page.
Pros:
- Large 110 nail magazine and up to 1000 nails per charge on a 3.0Ah battery suit long runs of baseboard and casing.
- Cordless 18V LXT design removes the compressor and hose, and the battery fits the large Makita 18V LXT system.
- Two firing modes, sequential and contact, give a choice between careful single placement and faster runs.
Con: Heaviest cordless pick in this set in owner discussion at about 7.7 lbs with a battery, and the XNB01Z maker product page did not surface in a makitatools.com search on 2026-11-06.
Owner review themes point to owners who praise the accurate placement from the tapered nose, the consistent driving in softwood trim, and the long runtime on a single charge. The recurring complaints are the weight and balance with a battery fitted, which can tire the wrist on overhead work, and weaker driving in dense hardwoods compared with the premium cordless picks.
Price: Check current price.
Check current price on AmazonMetabo HPT 2 in 18-Gauge Brad Nailer NT50AE2
Best for shop use and for anyone who already owns a compressor and wants the lightest nailer in this set.
Key specs are pneumatic, 18 gauge, with fastener length from 5/8 in to 2 in and a nail capacity of 100. It has a straight magazine, a 1/4 in air inlet, and an operating pressure of 70 to 120 PSI. It weighs 2.2 lbs. It has selective actuation for sequential and contact nailing, a tool-less easy-to-clear nose, a depth of drive dial, and a 360-degree adjustable exhaust port. It includes safety glasses, a no-mar tip, and a case.
Pros:
- Lightest pick in this set by a wide margin at 2.2 lbs, so it is easy to hold overhead on crown molding all day.
- Pneumatic power gives consistent driving without battery charging, and the tool-less nose makes jam clearing simple.
- Selective actuation, depth dial, and 360-degree exhaust give good control over placement and finish.
Con: Needs a compressor and hose, which adds setup and noise in a finished room, and it cannot run without an air supply.
Owner review themes point to owners who praise the light weight, the consistent depth, and the simple reliable pneumatic design that has stayed in production for years. The recurring complaints are the need for a compressor and hose, the noise of the compressor in a finished home, and the need to oil the tool and drain the compressor tank as the manual directs.

Check current price on AmazonQuestions to ask before buying
How do I stay safe when using a brad nailer for interior trim?
Wear eye protection and hearing protection every time you nail, and keep other people and pets out of the room while you work. Never point the tool at yourself or anyone else, even when it is not loaded, and never carry it with a finger on the trigger. Keep both hands clear of the nail path and away from the nose of the tool, and never reach across the line of fire to hold trim in place. Before clearing a jam, disconnect the air hose on a pneumatic nailer or remove the battery on a cordless nailer, then follow the maker manual for clearing the nose. A brad nailer has no blade guard like a saw, so the safety device that matters is the contact tip and the firing mode: use sequential mode for careful placement, and switch to contact mode only when you are sure of the placement. Kickback in a nailer is different from kickback on a saw, but a nailer can still recoil and a brad can deflect off a knot or a hidden nail, so keep your face back from the tool and your free hand behind the nailing line. Read the maker manual for your exact model before first use, and store the tool unloaded with the battery removed or the air disconnected.
What size brad nails should I use for baseboards, casing, and crown molding?
Use 1-1/4 in to 1-1/2 in brads for most baseboards and window casing, and 2 in brads where trim is thick or where the nail must pass through trim and drywall into a stud. For shoe molding and thin decorative trim, 1 in to 1-1/4 in brads are usually enough and leave a smaller hole. For crown molding, use 1-1/2 in to 2 in brads so the nail reaches solid wood behind the molding, and add a second nail where the molding meets a stud. An 18 gauge brad is thin enough for most interior trim, but it is not a structural fastener: use screws or a heavier gauge finish nailer for trim that must carry weight or resist pulling away from the wall.
Should I buy a cordless brad nailer or a pneumatic brad nailer?
Buy cordless if you work in finished rooms, move between rooms, or only nail trim a few times a year. A cordless nailer needs no compressor, hose, or setup, and it runs on batteries you may already own. Buy pneumatic if you already own a compressor, nail trim often, or want the lightest tool: the Metabo HPT NT50AE2 at 2.2 lbs is far lighter than any cordless pick here, and pneumatic tools drive consistently without charging pauses. The tradeoff is setup and noise: a compressor takes space, makes noise, and needs the hose routed through the house, and you must oil the tool and drain the tank as the manual directs. If you own no batteries and no compressor, the total cost of a cordless tool only model plus a battery and charger can be close to the cost of a small compressor and a pneumatic nailer.
How do I stop brads from splitting trim or leaving deep holes?
Set the depth with the depth dial or depth adjustment on your nailer, and test on a scrap piece of the same trim before nailing the real piece. Start with a shallow setting and raise the depth one step at a time until the brad head sits just below the surface. Keep the nose flat against the trim and square to the surface, and do not tilt the tool. Avoid nailing close to the end of a board or into a knot, because both raise the risk of splitting or deflection. For thin trim, use a shorter brad and a lower depth setting, and hold the trim firmly against the wall so it cannot move as the nail drives. If a brad does not set fully, do not fire a second brad on top of it: remove the battery or disconnect the air, clear the area, and check the depth setting before continuing.
How do I pick the right brad nailer if I already own batteries from one brand?
Start with the brand you already own, because a tool only nailer is far cheaper than a kit with a new battery and charger. DeWalt 20V MAX owners should look at the DCN680B, Milwaukee M18 owners at the 2746-20, Ryobi 18V ONE+ owners at the P320, and Makita 18V LXT owners at the XNB01Z. Check that your existing batteries are the right size for a nailer: a small compact battery is lighter for overhead work but may need more charging pauses, while a larger battery adds weight and runtime. If you own no batteries from any of these brands, compare the full cost of a tool plus battery and charger across brands, and pick the brand whose other tools you are most likely to buy next. The Metabo HPT NT50AE2 is the exception: it needs no battery at all, only a compressor, so it suits owners who already have air tools.
Frequently asked questions
What is an 18 gauge brad nailer best for?
An 18 gauge brad nailer is best for interior trim such as baseboards, window and door casing, crown molding, shoe molding, and chair rail. It drives thin brads that leave a small hole that is easy to fill, and it is strong enough to hold trim in place while glue or caulk sets. It is not suited to structural work, heavy trim, or fastening that must carry weight.
Do I need a compressor for a cordless brad nailer?
No. A cordless brad nailer runs on a rechargeable battery and needs no compressor, hose, or gas cartridge. The four cordless picks in this guide run on DeWalt 20V MAX, Milwaukee M18, Ryobi 18V ONE+, and Makita 18V LXT batteries. Only the Metabo HPT NT50AE2 needs a compressor, with an operating pressure of 70 to 120 PSI.
Why does my brad nailer leave some nails sticking out?
The most common cause is a depth setting that is too shallow, or a brad that hit a knot, a hidden nail, or dense wood. Test the depth on scrap trim first, raise the depth one step at a time, and keep the nose flat and square to the surface. For hardwoods, a longer brad and a higher depth setting may be needed, and the Milwaukee and DeWalt picks in this guide reach 2-1/8 in for thicker material.
How do I clear a jammed brad nailer safely?
Stop, take your finger off the trigger, and remove the battery on a cordless nailer or disconnect the air hose on a pneumatic nailer before touching the nose or magazine. Then follow the clearing steps in the maker manual for your exact model, and keep your hands clear of the nail path while you work. Never look down the nose of the tool, never point it at yourself or anyone else, and do not fire the tool to clear a jam.
Can an 18 gauge brad nailer be used on hardwood trim?
Yes, but with care. An 18 gauge brad holds well in softwoods and in many hardwoods when the brad is long enough to reach solid wood. In dense hardwoods such as oak and maple, use a longer brad, set the depth carefully, and test on scrap first, because short brads may not set fully. For heavy hardwood trim, a 16 gauge or 15 gauge finish nailer gives more holding power than an 18 gauge brad nailer.
How long should brad nails be for 3/4 in thick trim?
For trim that is 3/4 in thick, use a brad that is at least 1-1/2 in long, so about 3/4 in of the brad goes into the wood behind the trim. For trim fixed through drywall into a stud, use a 2 in brad so the nail reaches the stud. Shorter brads are fine for thin decorative trim and shoe molding, where the brad only needs to hold light trim against the wall.
