When it comes to impact wrenches, there are two main types: electric and air. Both have their own pros and cons that you should consider before making a purchase. Here's a look at the key differences between these two types of impact wrenches.
As the world moves farther down the path of battery power, cordless impact wrenches provide a viable alternative to traditional pneumatic versions. But are they really better? In this article, we’ll take a look at the pros and cons of each type, and hopefully come to a conclusion about which is better overall.
Round 1: Pneumatic Cordless Vs Pneumatic Impact Wrench: Maintenance
The maintenance for both of these machines is not particularly challenging. A cordless impact wrench requires virtually no maintenance, as there are no brushes to replace. A pneumatic impact wrench just needs a little oil here and there.
However, maintaining your compressor does require some work. You will need to oil it regularly, drain the air tank occasionally, keep everything free from moisture, and make sure that the tank still holds air properly. Years after your purchase, you will likely need to buy a new tank for your compressor.
Likewise, while your cordless impact drill could last years without needing any major repairs or replacements, batteries have a shelf life of 3-5 years (depending on the battery type). After this period of time has passed, you will need to replace your expensive lithium-ion batteries. This isn’t exactly maintenance per se, but it’s something you’ll still need to plan for in order to get the most out of your investment.
Round 2:Pneumatic Cordless VS Pneumatic Impact Wrench Power
Electric and air impact wrenches have different sources of energy. Electric impact wrenches get their energy from electricity, while air impact wrenches rely on air pressure.
Electric impact wrenches are easy to use. Just plug them into a wall outlet or socket and you’re good to go. You can also find cordless electric impact wrenches, which are powered by a battery.
Air impact wrenches, on the other hand, require an air compressor to function.
Air impact wrenches put out the most powerful torque. Their strength depends on the air pressure provided, which in turn depends on the size of the air compressor.
On average, you should aim for 90 to 120 PSI when operating an impact wrench. However, this also comes with a lot of drawbacks.
You’ll need to carry around the air compressor cylinder whenever you use the wrench. And depending on how long your hose is, the pressure will decrease as well.
For example, providing more pressure will give you more torque but it will also make the tool less controllable. So it’s up to you whether or not you want to deal with these issues!
The moment you press the button, an electric impact wrench will provide a high force on the nut. This can cause your hand to shake or the nut to break due to the excessive force.
On the other hand, air-powered impact wrenches are much more controllable. However, they have a lower power rating than their cordless counterparts.
For example, a cordless electric impact wrench may not provide enough torque and power to open up tight nuts or tighten loose ones.
Impact wrenches provide a lot of power and torque, which is great for getting jobs done quickly. However, this can also be tough on your arms and hands. Electric impact wrenches are easier to use because you don’t have to carry an air compressor around with you. They’re also easier because there are no wires or cylinders to deal with – just plug in and go!
Impact wrenches are great for getting jobs done quickly, but they can also be rough on your arms and hands. Electric impact wrenches are easier to use because you don’t have to carry an air compressor around with you.
When choosing between an electric impact wrench and an air impact wrench, it’s important to consider what you’ll typically use it for. Air impact wrenches are great for unjamming and loosening stuck or rusted bolts easily thanks to the extra torque they provide.
For homeowners and handymen who work on regular jobs and have to tighten and loosen regular nuts and bolts that aren’t too large in size, electric impact wrenches are a better choice. They’re cheaper than air impact wrenches, so they’re a good option for those who only need an impact wrench occasionally.
