What you need to know about cordless 18v impact wrenches

In the past, impact wrenches were predominantly air-powered or pneumatic, which made them more squarely in the mechanics’ domain. But as time goes, and technology continues to evolve, impact wrenches have continued to get better and better, making them a more viable option over the pneumatic ones. As a matter of fact, the modern-day wrenches do have a tremendous advantage over the historic or pneumatic ones, in terms of their mobility. I mean, without it being tied to a compressor with an air hose, you can take these tools anywhere you want them to be. With that knowledge, let’s take a look at how the 18v impact wrenches actually work.

How do they work?  

So, unlike the impact drivers or cordless drivers, which are best for drilling holes and driving screws, 18v impact wrenches are designed for loosening and tightening a number of hex-head bolts, lag screws, and nuts. The wrenches utilize both rotational force, known as torque, and short burst concussive blows (impacts), which enables it to deliver an unmatched amount of force.

However, it is important to note that all this strength wouldn’t be of any help if you don’t know how to use it. Fortunately, 18v impact wrenches are quite comfortable and easier to use due to their concussive blows that simply transfers the high energy to the fastener instead of your hands. As a result, the twisting motion felt when using the electric drill is eliminated.

Batteries (volts) – now, wrenches with higher voltage obviously gives you more power. But we can’t forget to state that there are those with smaller batteries, such as the 12v impact wrenches that are more compact, making them the best tools to carry out smaller jobs, working overheads, or even getting into smaller places. Generally, though, 18v impact wrenches are more versatile and easier to use given their advanced capabilities and features.

Batteries (Amp-hours) – this represents the number of amps to be discharged for an hour, continuously.

IPM/RPM – As IPM (impacts per minute) increases, so does RPM (revolutions per minute). the RPM helps to drive nuts, while IPMs kick in harder as the resistance goes up.
