Put a brad nailer and a finish nailer side by side, and it might be difficult to tell one from the other. Plus, when it comes to evaluating the nails—brad nail vs. finishing nail—there are similarities, too. Yet clearly there must be differences; otherwise, why would both be so popular?

We’ve put together this guide to help solve the brad nailer vs. finish nailer question. It offers not only a technical explanation of each tool, but it also gives examples of where you would use one nailer and not the other. Keep reading to find out how to pick the right tool for your DIY jobs.

Finish nailers are designed to shoot larger 16-, 15-, and even 14-gauge nails.

Nails are specified by gauge, which is the wire diameter used to make them. Higher numbers are thinner, and lower numbers are thicker. The thicker a nail, the more holding power it has.

The majority of finish nailers use thicker gauges than brad nailers. Typically, they are either 16- or 15-gauge nails. A few 14-gauge models exist, but they are not common. Finishing nails vary in length from 1 to 3½ inches.

However, the larger nail diameter requires more force to drive it, so when it comes to brad vs. finish nailer, a finish nailer is more powerful and weighs a little more than a brad nailer.

Brad nailers use smaller 18-gauge nails.

Brad nails (often just called brads), are 18 gauge, which is 0.0475 of an inch. They vary in length from ½ to 2½ inches. By comparison, a 16-gauge finish nail is 0.0625-inch thick. While the difference doesn’t seem like very much, the shorter length is a good indicator that a brad nail won’t hold material of the same maximum thickness as finish nails. They may not have the strength to penetrate hard timber either.

The benefit to being thinner is that the brad is less likely to split wood when going through it. Additionally, the head of the brad is less noticeable. Depending on the application of the brad nails, filling and sanding may not be required before painting, thus reducing the overall time a job takes.

For delicate finishing touches, a brad nailer is best.

The easiest way to look at the difference between a brad nailer and a finish nailer is perhaps to focus on the practical aspects of these tools and the jobs for which they are best suited.

A brad nailer is a light-duty tool. It might be used for adding narrow decorative moldings to plain panels or under stair treads. These tools are popular with crafters and model makers. They are often used for making birdhouses and bat boxes. Some woodworkers use brads as a temporary fix while glue dries because they are easy to remove and leave a very small hole.

Brads struggle with hardwoods, plywood, and dense particle boards like MDF. They simply aren’t strong enough to be driven through the denser materials. Most often they fold up on themselves, and they’ll sometimes jam the nailer. Therefore, a brad nailer is primarily used when working with softwoods.

Reach for a finish nailer for trim carpentry projects.

The finish nailer takes over when things get too big or too tough for the brad nailer: The finish nailer has the power needed for denser materials. It gets its name from being the tool that applies the finishing touches to construction tasks and is used for installing baseboards, crown moldings, window trim, and door casings.

While it’s an invaluable tool for the home remodeler, finish nailers are also popular with woodworkers. Finish nails are big enough to be used for furniture making (particularly carcasses) and other substantial workshop projects. That said, nail heads are still relatively small and easily hidden with filler.

Finish nailers offer two options when it comes to magazine designs. 

While there’s little difference when looking at most finish nailers vs. brad nailers in physical terms, there is one type of finish nailer that is easy to identify. The angled finish nailer’s nail magazine isn’t at 90 degrees to the gun, it’s at either a 21-degree or 35-degree angle. This makes it easier to get the nailer into smaller spaces or when fixing crown moldings. Frequently the magazine is longer, so it has higher capacity and needs to be loaded less often.

However, almost all angled finish nailers take 15-gauge nails. As 15- and 16-gauge nails are not interchangeable, it’s important to choose the right tool at the outset. It could also be argued that it’s less easy to nail at 90 degrees with an angled nailer, though the skill is soon learned. Brad nailers do not have angled magazines.

Both finish nailers and brad nailers come in cordless and pneumatic options.

Having read about the brad nailer vs finish nailer question in some detail, you may now have a better idea of which tool is right for your upcoming projects. Keen DIY enthusiasts and remodelers might find they need one of each. However, there is another choice to be made: Is it better to buy a pneumatic tool (a popular professional’s choice) or a cordless model?

Pneumatic tools are much cheaper than cordless nail guns. In fact, it’s not unusual for them to be a quarter of the price. They are also lighter because they have no motor or battery. This also means there are fewer parts that could go wrong or wear out.

The downsides are that pneumatic tools need an air compressor to drive them, which will be an extra expense if you don’t already own one. It also means you need a convenient power outlet to plug them into, or a generator to power them. Access to a compressor or power is seldom a problem on professional job sites, but it can be inconvenient at home. So while cordless brad and finish nailers tend to be more expensive, they are easier for the majority of DIY users to manage.

Brad nailers are less expensive than finish nailers.

Given that brad and finish nailers are broadly similar (except for the power output), you might expect prices to be more or less the same. However, when making comparisons between tools from the same manufacturer, brad nailers are often between 10 and 20 percent cheaper.

Not surprisingly there are big differences between the prices of budget tools and those from premium brands. It’s vital to thoroughly compare features to make sure you are getting value for money.
