Portable and powerful features of cordless impact wrench

Nowadays cordless impact wrench has become a great addition to any workplace. They have the capability of removing any fastener which they come across. When it comes to the matter of strength, air impact wrenches have a greater advantage. Though it cordless impact wrench may not replace a pneumatic wrench, yet it is a great addition to the toolkit along with an air compressor or the power cord.

There are certain battery-powered impact wrenches in the market as well as in online. Prior to buying ensure that the item you are going to buy is going to meet your power requirements and budget. They can range maximum from 12V to 24 V batteries. Most times, the higher battery voltage will allow you to make more torque rather than a lower voltage tool.

On the other hand, it’s always essential to verify the torque rating of the impact wrench that you are searching for and compare it with other models of the same price range. Additionally, another vital aspect to consider is a variable speed trigger or the torque setting. This allows you to have control over the torque that you are applying. On the other hand, without any sort of control over the torque amount, it’s quite easy to snap head portion of the bolt that you are installing or any sort of damage caused by the equipment that you are working with.

In case, if the impact cordless wrench doesn’t have torque setting, then no need to worry. There are various options like torque sticks. They are installed between the socket and the wrench and also allow a certain amount of fastener to be applied to the fastener. If space is considered as an issue, then another tool which can be used in this regard is the angle head impact wrench to reach the areas which are quite difficult for others. They usually don’t have the power of full-size impact. Actually, they are designed for tighter areas and are available handy while working with trucks and cars.

3 vital factors to consider while choosing the best cordless impact wrench

As mentioned earlier, a cordless impact wrench can be a great addition to the toolbox, but on the other side choosing a wrong one can make the purchase pretty much useless. The wrong selection can be either something which is not able to power the one which is required. Remember, it’s not too bad if you get the torque of variable torque and bulkier one. The underpowered wrench is quite worse and makes the tool very much useless.

While buying a cordless impact wrench, the most vital aspect to consider is the power. The main aim of using impact wrench is to loosen the tough nuts and bolts. If you are not having sufficient power, then you will be left with an over-sized ratchet.

With the cordless impact wrench, power supply comes from the battery and volt is the key specification here. It’s not good to have more volts as well. If you are pretty much concerned about the size of the cordless impact wrench, then you will have to look for the batteries with much fewer volts.

For some people having a charger which quickly charges your battery is pretty much essential. In the case of higher end cordless impact wrench, it will have chargers and battery gets full within 5minute. In the case of some older chargers, it is necessary to charge for about 3 hours. On the other scenario, if you are using a cordless impact wrench for much longer duration of time or if you are on brisk schedule and can’t afford time for charging batteries, then you will have to consider how fast battery can charge.

Finally, when it comes to choosing batteries, ensure to choose lithium ion batteries having higher energy density rather than nickel-based batteries, meaning you can have the same amount of power within the smaller package. Lithium ion batteries are pretty much expensive. If you are buying a higher cordless impact wrench it comes along with lithium ion batteries and it won’t affect the wrench that you are buying. But if you are looking for the older impact wrench, the difference just lies in the battery capacity. If you are buying a brand new cordless impact wrench, then make sure to check its power capacity (in terms of volts), what to consider in a charger and what the actual difference between various types of batteries are.

By using a cordless impact wrench, it’s possible and quite easy to dispense along with the air hose and the air compressor. It gives you the freedom to move quickly and conveniently around the workshop. In fact, it’s quite easy to use comfortably. These tools look more like that of a traditional cordless drill and use a battery for power. In order to apply for the proper amount of torque, it’s necessary to have a much greater control.

There are immense numbers of cordless impact wrench designed to suit everyone’s need depending upon their budgetary requirements of the individual. Most of the manufacturer’s designed wide array of tools ranging from cheap weekend tools which are designed for occasional purposes by using professional quality air guns. The initial outlay for a cordless impact wrench seems very high when it is compared to traditional items. It is essential to consider that without the need for full power air compressor, the entire purchase of the system is much lower and will be more affordable to the people as well and thus makes it accessible for residential purposes as well.

Significant features of impact wrench

The physics principles and mechanization are pretty much same for almost every product even though they vary in their models. Some of the most common features of the best cordless impact wrench are as mentioned below-

  • Power source

Depending upon the type of power source used, cordless impact wrenches are classified into three major categories. They are electricity, compressed air, and hydraulics. Compressed air and electricity are widely used in the field of construction as well as in automotive mechanical work, whereas hydraulics is used in the heavy industrial work.

    1. Compressed air

This type of wrench is commonly used in the car shops. It has air tank fitted on one side by providing them with the compressed air. Using a compressed air is very much powerful and the way you connect it to an impact wrench is completely a natural fit. Another major benefit of using these wrenches is, compressed air is very light weight and there is no need to carry batteries or motor to generate power. But you need to have a complete air tank.

    1. Electricity

They are not as powerful as that of compressed air, yet they are not bad either. It is available handy when you don’t have air tank available around you. They are suitable for many smaller jobs or for those who are working in their home workshop wherein it might not be comfortable enough to keep compressed air in hand. Another convenient option is to plug into the electrical socket.

These types of wrenches can be either corded or cordless. Each of these has its pros and cons. Corded impact wrenches are usually light weight since there is no attached power supply and there will be continuous electricity supply, yet mobility can be easily limited by locating the electrical outlet to which the wrench is plugged.

    1. Hydraulics

It can generate a huge amount of torque. Hydraulic motors generate more power to the hydraulic impact wrenches. It’s quite difficult to find in anyone’s home or in any automobile shop since its power exceeds more than any professional requirements. They are widely used in construction sites and factories where there is need of huge amount of torque.

      • Shape and size of socket

Impact wrenches are mainly available in two shapes- pistol and inline. Pistol wrenches have a hammer and also anvil situated quite above the grip whereas inline wrenches look just similar to that of an oversized screwdriver with anvil and hammer situated at the front portion of the grip. There are wide varieties of socket sizes, which are designed in order to fit various sized bolts and nuts.

      • Torque

Regardless of socket size, shape and how does it generates power, the vital feature is how much amount of torque does the impact wrench produces. Most of the wrenches will allow you to choose between various torque settings which allow you to adjust the torque amount based on the job requirement. Torque settings are very much important since it avoids over tightening of bolts or loosening of bolts. This can make the machinery fail, which on the other hand can lead to serious consequences.

How does it work?

A cordless impact wrench is available in various sizes and shapes. Some of them are designed in the form of a screw driver, whereas some others are designed in the shape pistols. Regardless of its shape and size, their working criterion is the same.

Inside of every cordless impact wrenches there is a rotating mass. The motor builds energy by using a rotation of that mass. This, in turn, creates a huge amount of torque which can’t be produced by any human. The rotating mass resembles that of a hammer and the operator feels only a small amount of impact.

Apart from generating huge amount of torque, cordless impact wrenches are pretty much more precise than humans and thus makes it ideal for a number of applications. Hence, it’s pretty much safe to make use of this powerful tool for the purpose of securing bolts in the car wheel or while working on the construction sites. Albeit, all the impact wrenches function in the same way, yet they differ from others in term of socket size, shape amount of torque and power source.

Impact wrench mistakes

      • Over tightening of bolts and nuts

This is the most common issue experienced by amateurs who usually underestimate the amount of torque applied by the impact wrench. So, in order to ensure that nut and bolts are properly tightened, stripping of threads is necessary. An impact wrench is mainly designed to lose the fixings rather than tightening them. In fact, it is also pretty much useful for removal of fixings.

Over tightening of fixings can be a great issue if not now but at the later stages, even if there is no question of damage. Obviously, most of us would have experienced the issue of struggling to remove the wheel nut in order to change the tire which has been fitted by the mechanic using an impact wrench. If the bolts are tightened according to manufacturer specifications, then the nuts can be easily removed using hands or using a wrench.

If the fixings are tightened beyond the manufacturer requirements, then obviously there is a risk wherein the threads stretch by allowing the fixings to loosen tension and it can be dangerous. The most common issue faced is the stripped thread. In this case, the process of fixing the issue is time-consuming as well as expensive task. If the threads are not in a proper condition while tightening them, then it’s better to take a suggestion from experts.

Remember that ordinary sockets are not at all designed to use with a cyclic load so that they tend to wear quickly and thus become oversized and make them slip on the fixing. The impact wrench sockets are usually heavy in weight and prevent them from damaging, slipping and wearing off.

      • Damaging threads

The damaging threads are caused due to cross-threading the nut or the bolt before tightening it using an impact wrench. One of the best ways to avoid this issue is through ensuring that nut and bolts are correctly threaded by hand prior to making use of an impact wrench. Bear in mind that your hands will be pretty much sensitive than a torque limited cordless impact wrench.

In fact, this is very much essential while using aluminium or any other soft metal fixings since these get easily damaged because of cross threading. In case, if the fixing can’t be done easily with hands, then it requires little modification.

      • Purchasing the wrong size cordless impact wrench

It can be too small or too large or it may not perform the task or may look awkward. One of the best rules is to consider in this regard is to find out the size of the fittings which can be used along with hand socket wrench.

At the next stage consider where actually you will be using this cordless impact wrench and for how many duration. For instance, let’s consider air impact wrench, it is quite smaller and has much greater capacity to weigh rather than a cordless wrench. Thus, makes it more suitable for using in restricted spaces for the longer duration of time. This makes cordless impact wrench as the perfect one for professional mechanics. However, a cordless impact wrench is considered as the best for both commercial as well as residential applications as there is no additional infrastructure required.

From the technical point of view, if you are aware of the torque required to release the largest fixing, then you need to check against the rating of the torque of the cordless impact wrench. Until the rating is pretty much greater than required torque, you will not be having any issues. While fixing the bolt you might have tightened it to a particular torque and torque, which is necessary to release, may be much greater. In such a scenario, consider torque rating up to 20% to 30% greater than required torque.

      • Purchasing the wrong type of impact wrench

People often do mistake by purchasing the wrong kind of cordless impact wrench. As mentioned earlier, each type of impact wrenches has its benefits and disadvantages based on its applications. While buying make it a point to consider battery indicator, torque limiter and extended warranty in order to get the right product for your task.
