The Best Framing Nailers: 4 Compared (and One to Skip)

RBE top pick

Makita AN924 21 Degree Full Round Head Framing Nailer

Check price on Amazon See why it wins Compare all

The Makita drives full round head nails to a full 3-1/2 inches, which is the combination that satisfies the strictest codes. The DEWALT cordless matches the 3-1/2 inch range, the full round head and the .148 inch shank, and removes the hose.

Two of these four nailers are DEWALT cordless twins that differ only in collation, which is deliberate. The two decisions in this category are collation angle and power source, and a matched pair is the cleanest way to see what the angle costs. The collation decision is the one with consequences beyond the tool. Twenty-one degree magazines use plastic strip and take full round head nails. Thirty degree magazines use paper tape and, in the great majority of cases, take clipped head nails, where a portion of the head is cut away so the nails sit closer together. Clipped heads hold less, and some building codes do not permit them at all, particularly in high wind and seismic areas. That makes the angle on the magazine a code question rather than a preference, and it is worth settling before you buy rather than at inspection.

RBE top pick

Makita

AN924 21 Degree Full Round Head Framing Nailer

Buy it

Full round head nails to a full 3-1/2 inches, which is the combination that satisfies codes that reject clipped heads.

Best for: Framing where the inspector requires full round heads and the shop already runs air.

$$$ · premium

Why we like it

• Twenty-one degree plastic collation takes full round head nails, which hold better and are accepted in jurisdictions that prohibit clipped heads.
• Drives 2 in. to 3-1/2 in. with shank diameters up to .148, so 16d framing nails are within range.
• Pneumatic, so there is no battery to run down on a tool that fires continuously through a day.
• Makita states the head type explicitly in the product name rather than leaving it to be inferred from the angle.

Know before buying

• Needs a compressor, hose and fittings, none of which appears in the price comparison.
• Plastic collation shatters on firing and throws fragments, which is a real argument for eye protection and a nuisance to clean up.
• Twenty-one degree magazines are bulkier than 30 degree ones and awkward between close studs.
• Plastic collated nails can cost more than paper tape equivalents.

DEWALT

DCN920B 20V MAX XR Brushless Cordless 21 Degree Plastic Collated Framing Nailer

Buy it

Full round head nails to 3-1/2 inches with no hose, the code-safe collation in a cordless body.

Best for: Framing and remodelling away from a compressor, including jurisdictions that require full round head nails.

$$$ · premium

Why we like it

• Drives 2 in. to 3-1/2 in. nails in .113 to .148 gauge, matching the Makita on both length and shank.
• Twenty-one degree plastic collation with full round head nails, the head shape codes that reject clipped heads accept.
• Cordless and brushless, so there is no compressor, hose or fittings and no line dragged across a deck.
• DEWALT states 8.65 lb tool only, and the flywheel stays spinning for 6 seconds after the trigger is released to cut the wait between shots.

Know before buying

• A 36 nail magazine, the smallest here, so it reloads more often than any other tool in the group.
• Bare tool, so batteries and charger are a separate and significant cost.
• Plastic collation throws fragments on firing, with the same debris and eye protection issue as the Makita.
• Cordless framing nailers are heavier at the nose than pneumatic and slower between shots on production runs.

Metabo HPT

NR90AD(S1) 3-1/2 Inch 30 Degree Paper Collated Framing Nailer

It depends

A 7.0 lb, 30 degree paper strip pneumatic that drives the full 3-1/2 inch range, on clipped head nails only.

Best for: Production framing in jurisdictions that accept clipped heads, where a light tool and the full 3-1/2 inch range matter more than head shape.

$$ · mid-range

Why we like it

• Drives 2 in. to 3-1/2 in. nails with shanks from .113 to .148 in., so 16d framing nails are within range.
• Metabo HPT states 7.0 lb, against 8.65 lb for the DEWALT cordless pair.
• Paper collation leaves no plastic fragments, and the magazine holds 50 to 74 nails.
• Selective actuation switches between sequential and contact nailing, with tool-less depth adjustment, 70 to 120 PSI operation and a 5-year warranty.

Know before buying

• Metabo HPT's manual lists clipped-head nails only for this model, the head shape some building codes do not accept.
• Pneumatic, so a compressor, hose and fittings are part of the real cost.
• The spec table lists no dry-fire lockout, so the magazine can run empty without the tool stopping.
• Paper collation degrades if it gets damp, which is a genuine issue on an open frame.

We'd skip it

DEWALT

DCN930B 20V MAX XR Brushless Cordless 30 Degree Paper Collated Framing Nailer

Skip it

The 30 degree twin of the DCN920B, giving up the full round head and the heaviest shanks for a bigger magazine.

Best for: Crews already stocked with 30 degree paper tape nails, in jurisdictions that accept clipped or offset heads.

$$$ · premium

Why we like it

• Drives 2 in. to 3-1/2 in. nails, the same length range as its 21 degree sibling.
• A 55 nail magazine, with an optional extended magazine that holds two strips.
• Paper collation shears cleanly, so there is no plastic debris underfoot.
• Cordless and brushless, so no compressor, hose or fittings.

Know before buying

• DEWALT's manual lists clipped or offset round head nails at 30 to 34 degrees, the head shapes some building codes do not accept.
• Shanks top out at .131 in., short of the .148 in. its 21 degree twin and the Makita take.
• Same body and the same 8.65 lb stated weight as the DCN920B, so the 30 degree magazine buys no real size advantage.
• Bare tool, so batteries and charger are extra on an already premium price.

How we judged the field

Head shape first, because it is the only thing in this comparison that can fail an inspection. Collation angle determines it: 21 degree plastic strip takes full round head nails and 30 degree paper tape is predominantly clipped head, and some building codes do not accept clipped heads, particularly where high wind or seismic loads are designed for. Then nail length, because framing schedules specify sizes and a 16d common nail is 3-1/2 inches, so a tool stopping at 3-1/4 cannot drive it. Then collation material, which is a debris and weather question rather than a safety one. Then power source, weighed against what a pneumatic tool actually costs once a compressor, hose and fittings are added. Two of the four are DEWALT cordless twins that differ only in collation, which is deliberate, because the pair isolates the collation variable rather than confounding it with brand.

The Makita AN924 is the pick because it is the only pneumatic here that combines the code-safe head shape with the full length range. Twenty-one degree plastic collation means full round head nails, which hold better and are accepted in jurisdictions that prohibit clipped heads, and it drives 2 to 3-1/2 inches with shanks up to .148, so a 16d framing nail is within range rather than just outside it. Makita puts the head type in the product name rather than leaving you to infer it from the magazine angle, which is more useful disclosure than it sounds given how many buyers do not know the angle implies the head. Being pneumatic, it fires continuously without a battery to manage. The costs are the familiar pneumatic ones plus one specific to the collation: a compressor, hose and fittings are part of the real price, plastic strip shatters on firing and throws fragments that make eye protection non-optional, and the 21 degree magazine is bulkier and more awkward between close studs than a 30 degree one.

The DEWALT DCN920B is the second buy and the right answer when the hose is the problem. It runs the same 21 degree plastic strip as the Makita, so it drives full round head nails, and DEWALT’s manual lists the same 2 to 3-1/2 inch length range with shanks from .113 to .148, which puts a 16d framing nail in range without a compressor. On a remodel or a repair away from power that is the difference between working and not. It is brushless, DEWALT states 8.65 pounds tool only, and the flywheel keeps spinning for 6 seconds after the trigger is released so repeat shots do not wait on spin-up. The costs: the 36 nail magazine is the smallest here and means more reloads, it is a bare tool so batteries and a charger are a real additional cost, plastic collation throws the same fragments as the Makita, and it is nose-heavy compared with pneumatic.

The Metabo HPT NR90AD(S1) is the it-depends, and the whole case turns on your code. On the numbers it is strong: Metabo HPT lists a 30 degree paper strip magazine holding 50 to 74 nails, a 2 to 3-1/2 inch length range with shanks from .113 to .148, 70 to 120 PSI operation, selective actuation, tool-less depth adjustment, a 5-year warranty and a stated 7.0 pounds. Paper collation means no plastic fragments. The catch is in the owner’s manual, which lists clipped-head nails as the only nails for this model. Where the code accepts clipped heads, it covers 16d framing on a light tool for much less than either cordless gun. Where the inspector wants full round heads, no spec on the page makes up for that. It is also pneumatic, so a compressor, hose and fittings are part of the cost, the spec table lists no dry-fire lockout, and paper strips go soft when they get damp on an open frame.

The DEWALT DCN930B is the skip, and the reason is its own sibling. It shares a body, a manual and an 8.65 pound stated weight with the DCN920B, and it drives the same 2 to 3-1/2 inch nails. What changes is the magazine: 30 to 34 degree paper collation, which DEWALT’s manual pairs with clipped or offset round head nails, and a shank range that stops at .131 inches. In return you get a 55 nail magazine against 36, an optional extended magazine that holds two strips, and paper collation that leaves no plastic debris. That is a thin return for giving up the head shape some codes require and the heaviest fastener in the group, and the 30 degree angle does not buy a lighter tool here: the pneumatic Metabo HPT takes 30 degree nails up to .148 at a stated 7.0 pounds. If your crew already stocks 30 degree nails and your inspector accepts clipped or offset heads, it is a capable gun. For anyone choosing a cordless DEWALT from scratch, the 21 degree twin is the better buy.

Makita AN924 21 Degree Full Round Head Framing Nailer vs DEWALT DCN920B 20V MAX XR Brushless Cordless 21 Degree Plastic Collated Framing Nailer: which should you buy?

Both tools run 21 degree plastic strip with full round head nails from 2 to 3-1/2 inches and shanks up to .148, so the code question is settled either way and the split is power source. The Makita is pneumatic, carries 73 nails to the DEWALT’s 36, and fires all day without a battery to manage, at the cost of a compressor, hose and fittings. The DEWALT removes the hose and adds a battery and charger to the real price. For production framing on an open frame, where a hose is barely noticed, the Makita is the safer default. For remodel work in an occupied house, where dragging a hose through finished rooms is genuinely disruptive, the cordless DEWALT earns its place.

What to look for

• The collation angle, read as a head shape question: 21 degree plastic means full round head, 30 degree paper tape usually means clipped head, and some codes reject the latter.
• Your local code before the tool: the head shape restriction is a jurisdiction question, most common in high wind and seismic areas, and it settles the angle for you.
• Maximum nail length against the schedule: a 16d common nail is 3-1/2 inches, and a tool stopping at 3-1/4 cannot drive it however good it otherwise is.
• Shank diameter range: heavier shanks carry more load, and .148 is the top of this group.
• Collation material as a site question: plastic throws fragments and shrugs off weather, paper is tidy and goes soft when damp.
• The full cost of pneumatic: a compressor, hose and fittings are part of the purchase and never part of the shelf price.

Our final take

Framing nailers are compared on magazine capacity and weight, and decided by the head shape their collation angle commits you to. Find out what your inspector accepts, let that choose the angle, then check the tool reaches 3-1/2 inches before anything else. A gun with the right head shape and the wrong length range solves half a problem.
