And moreover, the processes are so lengthy and time-consuming that it gets trickier through the way.

So we understand when looking for the best impact wrench you must find it quite too messy to sum it up to the one you need for yourself. Here we have sorted out all the necessary features that you might find necessary in your impact wrench and left you to do the easiest job, to choose.

Best-1-Inch-Impact-Wrenches-Buying-Guide

Types

There are generally two types of impact wrenches and – electrical and air powered. As both types have their pros and cons, let’s shed some light on them separately.

Electrically powered

Electrical powered impact wrenches are generally lightweight and portable. But they can’t generate much power compared to the air-powered ones. So they generally can’t be used for heavy-duty applications. But they are quieter.

Air-powered

On the other hand, air-powered impact wrenches are heavier and gruesome as they need to have an air compressor attached to themselves. So they are very noisy. But they can generate much more power than the electrical impact ones.

Torque

The most important thing to consider while buying an impact wrench is torque. While comparing different styles of impact wrench you should always check the maximum amount of torque they can generate. The amount of torque differs from one wrench to another.

Some of the best impact wrenches have the settings to set the torque at different levels so they can work more efficiently in different situations. This distinct feature makes them more versatile than simple impact wrenches with single torque settings. So if you are a professional or planning to use the wrench for a variety of situations then I’ll suggest you choose one with multiple torque features.

When buying an impact wrench with single setting torque it’s best to check carefully what amount of torque you need for your work as more torque doesn’t always mean a better result. It needs to match your required work to give you the best performance.

Impacts Per Minute ( IPM)

Impacts per minute of an impact Wrench shortly known as IPM refers to the amount of time the hammer hits the output shaft’s anvil in a minute. So basically, it determines the tightening speed of the tool kit. It’s one of the unavoidable features to consider while choosing the topmost 1-inch impact wrench for yourself.

IPM gives you the idea of how quickly the wrench can loosen a bolt associated with enough torque. A wrench with higher IPM can work faster than a wrench with lower IMP. So it’s always better to choose an impact wrench with higher IPM to work efficiently and make the best of your time.

Rotation Per Minute (RPM)

Like IPM, RPM is another determining factor for the best impact wrench. RPM the abbreviation of rotation per minute describes the speed with which the output shafts spin with no load. It gives you the idea of how quickly the wrench can pull off a nut or drive it in when it’s already in a loose state. Higher RPM gives the privilege of finishing the work very quickly.

Grip and Ergonomics

Unlike strap wrenches, Impact wrenches are heavy machines and a nice grip is not a luxury at all. So to be able to work with ease and comfort you need to be able to grip the tool comfortably in your hand. If the product is not well-engineered, it becomes difficult to work with it for a long time.

Before buying the product you need to make sure that it fits well in your hand. Nowadays most of the products in the market are well balanced and they use comfortable grip materials like rubber which reduces strain and gives the privilege to use it for applications demanding prolonged work time.

Some wrenches may not feature rubberized handles. Instead, their metal handles are made grab-friendly. If you find a 1-inch impact wrench having required features within affordability and especially the working period isn’t too long, a non-rubberized handle may not bother a lot.

Sound level

Impact wrenches generally tend to be quite loud. They can be quite harmful if you work with it for a long time in such loud noises. Some manufacturers are making products that make less noise than usual. Also, most of the products come with a sound muffler that helps as well.

So if you are sensitive to sound and might find the noise a nuisance make sure you look into this matter and choose one that matches your requirement.

Weight

It’s hard to work with a heavy weighted tool kit as they slow down the pace of the work which will be a hassle if you are a professional. At the same time, it’s hard to grip them better and work comfortably for a long time. Whereas light-weighted impact wrenches give you the privilege to work for a long time comfortably without stopping.

Aluminum alloys are the key to unfold the realm of lightweight impact wrenches. They are both corrosion and rust-free too! When you are working for a short time, weight might not feel much but a longer working period with heavy weighted tool kits will surely hit you hard.

Shapes And Socket Size

Socket sizes are designed to fit nuts and bolts of different sizes and different socket works with different shapes of cordless impact wrenches. So you need to check which socket size you will need to fit the bolts you need to work on before choosing which one to buy.

No-load speed

No-load speed is the speed at which the impact wrench turns when there’s no load. It’s normal that the higher speed is more beneficial and works more efficiently. But sometimes higher speed comes with low torque. So it will always be better if you look into it before buying the wrench.

Torque Adjustment Features

If you are looking for one of the best impact wrenches for your work then you might want to consider this feature. Torque adjustment features help in the control of the torque while using the wrench. It reduces the chance of twisting or shearing off the threads of the bolt or worse, snapping off the bolt.

Warranty

As you are going to spend a decent amount of money on buying the tool kit, it’s always best to buy one with a good warranty. Usually, most of the products in the market come with one or two years of warranty. But there are also products that offer a lifetime warranty but they cost a lot higher than most other products available in the market.

Durability

Most of the manufacturers these days use alloy materials as they are light weighted and have good durability that will last you a long time. Stick with such materials to achieve a decent level of durability.
