The 9 Best Pneumatic Drills
This wiki has been updated 21 times since it was first published in April of 2016. Designed to effectively penetrate tough materials, such as hard, thick wood and different types of metals, these pneumatic drills use the power of compressed air to attach screws or bore holes efficiently. Available in both angled and straight designs, these options include models that should work for a wide variety of professional jobs and do-it-yourself projects.

Breathe In, Breathe Out
Even before pneumatic tools came around, scientists like John Wanamaker and Alfred Beach demonstrated how effective tubes are at moving not just the mail, but even people.
In the year 1650, famed German physicist Otto Von Guericke paved the way for air compressors when he invented a vacuum pump to help him study pressure and combustion. Additional engineers would release upgraded designs in the coming decades, until the first compound compressor was invented in 1829. Even before pneumatic tools came around, scientists like John Wanamaker and Alfred Beach demonstrated how effective tubes are at moving not just the mail, but even people. By the middle of the 19th century, compressed air had broken into worldwide industry during the digging of the Mount Cenis Fréjus Rail Tunnel, and the stage was set for the popularization of pneumatic tools. In 1871, Simon Ingersoll of historic manufacturer Ingersoll-Rand released the steam-powered rock drill, the precursor to today's jackhammers, and the first publicly available, air-powered tool.
Over the next 100 years, improvements in cooling, power consumption, storage capabilities, lubrication, and more all came together to help turn air tools into some of the most useful implements ever made for construction and demolition.
The Pros And Cons of Air Tools
There are various reasons why pneumatic tools have earned a special place in the hearts and workshops of engineers, builders, and mechanics worldwide. One of their defining characteristics is the strength of both their materials and their output. Air tools are well known for delivering massive amounts of torque, able to successfully free rusted nuts, drill through high-strength steel, or shatter foot-thick concrete. And because they're driven by simple compressed air, that high level of force is variable. That way, if you're working with a more sensitive piece of equipment, a little bit of pressure release will ensure that nothing takes any damage. Since they don't contain batteries or drivetrains of any sort, pneumatics are often lighter than their electric counterparts, and ease of use means a whole lot if you're disassembling a dozen vehicle undercarriages per day. The newest options have even added Bluetooth support, to help parse and organize the data surrounding your latest project. Finally, the air tools themselves are significantly less costly than electric versions would be, because they all share the same power source.
Unfortunately, that power source is somewhat of a drawback to pneumatics. One thing that no one has addressed very effectively is the incredible noise of a strong compressor. And though they're usually long-lasting, multipurpose appliances, they can be wildly expensive, especially the most reliable brand names and feature-packed models. Plus, even the mid-range models require regular maintenance to ensure proper and safe operation. Of further contention is the air hose, ever so stiff and leaky. The solid nature of a hose under high pressure can make it challenging to maneuver around busy garages or tight projects, and even the best ones are liable to develop faults somewhat quickly.
Which One do I Need?
You may hear the term "pneumatic drill" used to describe one of a couple different items. Particularly in Europe, it's long been a synonym for the jackhammer. This is a bit misleading, because in this sense, the drill doesn't really drill at all, but rather jabs a high-impact steel tip downward to demolish whatever is beneath it — usually solid rock, concrete, or asphalt. These monstrous tools are almost exclusively meant for professionals, and the average DIY enthusiast should probably avoid them. But if you're fixing foundations, installing a new driveway, or clearing away space-hogging rocks, it may be something you need to consider.
A simple, air-driven drill will fulfill a lot of hobbyist needs, and they're generally among the least expensive ways to go.
Taken at face value, the term could simply refer to a drill that's pneumatically powered. And within that classification there are still more choices to make. A simple, air-driven drill will fulfill a lot of hobbyist needs, and they're generally among the least expensive ways to go. On the other hand, anyone with heavy construction tasks like sinking anchors in concrete should look into purchasing a rotary hammer. These ultra-powerful designs spin a chisel while using pressurized air to literally bring the hammer down on top of the rotating bit. This has the effect of ripping into concrete or stone while also carving away material, leaving a relatively clean hole rather than a pile of shattered rock.
Yet another type of air-powered drill is alternately called the impact hammer or impact drill. Shaped roughly like a traditional handheld drill, this type stores kinetic energy in an internal rotating mass, which is suddenly and repeatedly harnessed to deliver massive force in one circular direction or the other. These you'll find at auto shops and racetracks, extracting lugs nuts in two seconds or less with an unmistakable zipping sound. Their sudden rotational force helps them liberate some of the most frozen nuts and bolts — if an impact hammer can't break it free, it's probably time to just drill it out.
A slightly smaller type of impact hammer, the impact driver, looks a bit like a simple pneumatic screwdriver next to its other, larger cousins. While such screwdrivers are available, the impact driver actually tends to pack more punch than it appears to, and it's easy to move around with thanks to its light weight.
Each of these types of pneumatic drills are focused on specific tasks, so you may end up with more than one of them. But that's okay; air tools are exceptionally resilient, and generally make good investments. Plus, considering the stone-shattering levels of torque that come in an essentially handheld package, there's at least a little fun to be had in exercising the power of power tools.
As with any such implements, always take the necessary safety precautions. Make sure all lose clothing and hair is contained, and don't forget personal protective equipment such as gloves, ear protection, and safety eye wear. In fact, if you're using any of these any work, it's entirely possible that your employer will require OSHA-approved glasses, and that's not a bad thing. Safety and living to build another day are always of prime importance.
