In order to understand rivet guns, the first thing to do is understand how a rivet works. Blind rivets, often referred to by the brand name POP rivets, are an incredibly useful fastener designed to hold two materials together with a clamping force. POP Rivets are comprised of two pieces: the body and the mandrel. The mandrel goes through the inside of the body and gets pulled during installation. As the mandrel is pulled through the body, it deforms the back of the body. Once the deformed portion grips against the back of the installation material the mandrel snaps leaving a clean finished application. It is common for this type of rivet to be used when you cannot get to the back of an installation earning this fastener the name of Blind Rivet. 
Knowing how rivets work is great but how do you install them? A rivet requires a tool that keeps the hat of the rivet firmly pressed against the installation surface while simultaneously pulling the mandrel away from it. These tools are commonly referred to as rivet guns, riveters, rivet tools or riveting tools. Not only are there many things to call a rivet gun, there are also many varieties.
Types of Rivet Guns:
- Hand Rivet Gun
- Heavy Duty Lever Riveter
- Cordless Battery Riveting Tool
- Pneumatic Rivet Gun
While not all rivet guns were made equal, it is easy to identify the type of rivet gun needed for an application. Read along as we cover the pros and cons of each type or riveter.
Hand Rivet Gun 
Hand powered POP rivet guns work with a simple lever and squeeze technique. The first step when using one, is to choose the appropriate sized nose piece. Rivet guns normally come with several options to fit a range of blind rivets. Hand-operated riveters fit a variety of rivets, are usually made of mostly steel with a rubber grip and offer the cheapest cost.
Hand Rivet Guns are an excellent choice for the occasional user. If you find your project having just a few rivets, then this will do the trick. The biggest con on this riveting tool is the squeeze and the amount of time it takes. Used repeatedly, it can be very stressful on the hands, wrists and forearms making it less than ideal for projects requiring many rivets.
Heavy Duty Lever Riveter 
Heavy Duty Lever Riveting Tools are the next step up in rivet guns. They also come with nose pieces but work with a wider range of rivet sizes. Lever rivet tools tend to be more heavy duty than a hand rivet gun and are easier on the user. Due to their larger size and lever action, they reduce the amount of physical strength required by the hand riveter. They also come with a collection bottle that catches the snapped mandrels after installation.
To install a rivet using the lever riveting gun, first, open the arms all the way. Then insert the mandrel into the nose piece. Once the body reaches the nose piece, insert it into the installation hole. Then squeeze the two handles together. This will pull the mandrel in and snap it off. Now hold the lever rivet gun so the nose piece is in the air and open the arms. This will release the hold on the mandrel and it will fall into the bottle catch.
The heavy duty lever riveting tool is an excellent tool found on many job sites. It makes installing blind rivets easier than using the hand riveter but is still manually done. It does come at a higher price point than the standard hand riveter but also comes with the ability to use a wider and larger range of rivets.
Cordless Battery Riveting Tool 
Battery Powered POP Rivet Guns come in many varieties. The two main types function basically the same way, except for the last step. One type of battery powered rivet gun spits the mandrel out from the front of the gun and the other pulls the mandrel into a mandrel holder, so you do not need to worry about them until emptying the catch.
Battery powered riveters are great for the job site. They offer the versatility of not having a cord and the ease of simply pushing a button to install the rivet. Choosing the version with the mandrel catch is typically more expensive than the other battery powered option. The catch version makes installations faster by collecting the mandrels for you but be careful not to over-fill the catch or the gun may jam.
Pneumatic Rivet Gun 
Pneumatic Rivet Guns are powered by compressed air to very quickly and easily install blind rivets. With a built-in catch, the pneumatic riveting tool is easily the fastest way to install rivets.
The downside to pneumatic riveters is that they require a hosed connection to compressed air. This limits their versatility and portability more than any of the other tools available, but if the project requires installing a large number of rivets, this is undoubtedly the best tool to use to get it done.
Which Rivet Gun is the Best?
Now that we’ve gone over the many varieties of riveter tools, it’s time to determine which to buy when. Since one riveting tool isn’t necessarily “better” than the other we will instead identify which tool you should get depending on your situation.
- Hand Rivet Gun – This tool is cost effective and ideal for small shops that use smaller size rivets sparingly. They require significant pressure to use and leave mandrel collection to the user which can be a pain.
- Heavy Duty Lever Riveter – The lever riveter is a step up. It’s a little more expensive but does everything you want the hand riveter to do and can’t. It works with larger sizes than the hand rivet gun and makes installations easier by increasing the leverage on the handles. The lever rivet tool comes with a mandrel catch to make cleanup easy.
- Cordless Battery Riveting Tool – Ignoring the differences in battery riveters, both types come with a critical benefit: versatility. They offer powered installations without any cords. They are an ideal choice when commonly working with rivets on job sites.
- Pneumatic Rivet Gun – Air-powered tools in general boast performance at the cost of being attached to a compressor. The Pneumatic Rivet Gun is no different. If the job calls for an excessive number of rivets, then this is the tool you want by your side.
Conclusion
While many tool varieties have options available that are totally unnecessary, the rivet gun varieties are different. Each tool has a place in each situation and they perform very well when placed in those situations. Before buying one for yourself, decide what you work with the most often and be realistic about the goals you wish to achieve with the tool.
