During the last few years, power nailers have evolved with new features and greater reliability. For anyone interested in getting a lot of building done in as little time as possible, the choices have never been better.

When Paslode invented the air nailer back in 1959, nothing much happened. Most professionals weren’t interested. It took 25 more years for air nailers to begin appearing on jobsites in a big way, and another decade after that before they became commonplace.
But if the power nailer freight train was slow to leave the station, it’s gathered plenty of steam now. Today these tools are standard equipment, even for some hobbyists. Pros wouldn’t even think of framing a house, shingling a roof or trimming out a door without something to wrap their trigger finger around. Power nailers are now indispensable.
Part of the change comes thanks to innovation. Over the last few years, nailers have become a hotbed of new features and greater reliability. For anyone interested in getting a lot of building done in as little time as possible, the choices have never been better.
So what are you building these days? Whatever it is, there are innovative, reliable power nailers to help you work better, work faster and have more fun. Here are a few key things to consider as you make your choice.
Nailers for Framing
The world’s first power nailers were built for driving 21⁄2″ and 31⁄2″ framing nails propelled by compressed air. While this segment of the nailer category is still a mainstay of the market, significant innovations make these tools easier to use and more productive.
The first thing you’ll notice when you pick up one of today’s best air-powered framing nailers is their light weight. You can thank advanced housings for most of this gain. Bostitch (7.8 lbs) and DeWalt (7.5 lbs) are currently in the lead for the lightest framing nailers going. Most manufacturers offer framers designed to shoot one of two kinds of nails: round-head nails (maximum nail holding power, lower magazine capacity), or clipped-head nails (lower nail holding power, higher magazine capacity).
Another thing you need to know about is air hoses. You can still buy the heavy rubber type that has been a mainstay of the industry for years, but you don’t have to. Thin, flexible, lightweight hoses bring ordinary air nailers that much closer to hoseless status. My favourite lightweight air hose right now is the Prozhose by Bostitch. It’s made of thin-walled polyurethane and costs about $1 per foot.
Want to get rid of the air hose yet still drive framing nails? Consider a hoseless, combustion-driven framing nailer. These tools pack all the punch needed to drive ring-shank nails up to 31⁄2″ long into the hardest wood, without the need for an air hose or compressor. The energy that makes it all happen comes from combustible gas stored in a disposable metal canister. Each canister is good for about 1,000 shots and costs less than $10. An onboard, rechargeable battery ignites the gas and powers a fan to clear exhaust fumes.
So why isn’t everyone using gas nailers? While they’re handier than air-driven models, they’re not quite as fast. They also stop working reliably in cold weather as the gas becomes harder to ignite.
Paslode pioneered the gas nailer and had the market all to themselves until about a year ago. That’s when Hitachi upped the ante in the gas nailer game with a gas framer that has soft overwrap handle grips and a faster battery charger. Hitachi guns accept Paslode gas cartridges, the current industry standard.
Nailers for Roofing
If anyone ever needed a hoseless nailer, it’s when you’re up on a roof bamming down shingles. Why doesn’t anyone make a hoseless roofing nailer? Speed, that’s why.
Over the years several companies have attempted to market a hoseless roofing nailer, but all these tools failed in the marketplace. Professional roofers need to launch rapid, bump-fire volleys of nails as they work, and no hoseless model to date has been able to deliver this performance. Both battery and gas-powered designs require at least a couple of seconds cycling time between shots, and that’s simply too slow for the shingle guys.
The best tool companies have been able to do is make their air-powered roofing nailers light in weight, with a big magazine filled with coiled-collated nails. Couple one of the new-generation magnesium roofing nailers with a thin-walled, polyurethane air hose, and you have the best machine that’s currently available. Regardless of which model you choose, remember two things. Be sure to adjust air pressure so nail heads are set flush with the shingle surface. Nails too deep will allow shingles to blow off in the wind. Nail heads that are too high will damage the shingles that cover them. Also, be sure everyone on the roof wears safety glasses, whether they’re using the nailer or not. Roofing nails are collated with wire that flies around with each shot.
Nailers for Finishing
Lightweight, air-powered nailers are currently the most common models for driving finishing nails because they’re cheap, they work well and they’re familiar. While you won’t regret buying an air nailer for finishing, there’s a question you need to think about. Do you really want to deal with the hassle of a compressor and hose when the biggest reason for tolerating them doesn’t really apply?
Framing and roofing are about speed, and in this game you must have a reservoir of quick-access power stored nearby in the form of a tank full of compressed air. This allows rapid firing in exchange for the hassles of a hose. But finishing is different. It’s at least a little slower than rough work, and that means the slightly slower, self-powered nailers start to make more sense.
You’ll find gas-powered finishing nailers that work well, but one of the nicest hoseless finishing nailer technologies is also the youngest. It uses the same rechargeable battery packs that power drills and saws, but in a unique way. In this case, the stored electricity is harnessed to power an internal motor that drives nails via a flywheel inertia system. You pull the trigger, hear a whirring sound for a second, then BAM! The nail disappears into the wood. Battery finishing nailers are also quite a bit quieter than gas versions.
Until recently, battery finishing nailers weren’t as good as their air-powered cousins. Depth of nail control was unpredictable and hard to adjust. But all this has changed. At the moment the 18-volt DeWalt model is my favourite battery powered finishing nailer. It offers precise nail depth control via a side-mounted dial. This level of control is something I haven’t seen on any air nailer yet – air powered or otherwise. The tool drives 300 to 800 16-gauge nails per charge, up to 21⁄2″ long.
Few of us have time to spare these days, whether we’re building for money or for the love of it. While hammers are great and will always be around, it’s hard to pass up the chance to work two or three times faster while maintaining all the same quality. This is the power nailer advantage. The only thing you have to wonder is why it took so long to catch on.
