Our Take on this cordless wrench:
Cordless Impact Wrench Buyer’s Guide
Before impact wrenches became popular, users had an option in the impact drivers. In most general DIY functions, the users opted for the impact drivers due to their higher torque value and general purpose. This pushed the manufacturers of the impact wrenches to come up with equally effective DIY tools in the name of the cordless impact wrenches. The options are more compact than the original designs and more effective than impact drivers.
The advantage is that they are compact-built and thus great for auto-mechanics and amateurs. They are convenient for removing lug-nuts from tire-rims. Judging by the customers’ cordless impact wrench reviews, the tools are impressive, and thus are a must-have at home in your garage and inside your car’s trunk. The tool is fast and effective in removing and tightening screws and bolts. It guarantees that your DIY project is done fast and effortlessly.
What’s the Difference between the Impact Driver and the Impact Wrench?
Generally, the impact wrench is heavier and more powerful than the impact driver. The designs of the impact wrenches enable them to produce more torque power than their driver counterparts. In terms of the drive, the impact wrench employs a ½” drive while the drivers employ a ¼”. On a functional basis, the impact drivers are suited for driving screws while the impact wrenches are designed to fasten or loosen sockets. However, you can convert your impact driver’s drive from a ¼” to ½” (as in the case of the impact wrench) by adding an adapter.
The adapter allows you to use the impact driver with the socket drivers. Most homeowners don’t find much use in the impact wrench since its activities are vast, and this translates to them being expensive. Nonetheless, they can use the wrenches in removing bolts and nuts at home. On the other hand, the impact drivers are designed for both DIY and professional use. They are compact and give enough torque for the home application. However, this does not mean that they are superior to the impact wrenches.
What to Look For in a Cordless Impact Wrench?
To find the best cordless impact wrench for the money that you have, you should consider four things. To begin with, you should go for an option that has high power. For the best performance, the wrench should give deliver 200 torques or more. Secondly, the cordless impact wrench should have a higher Rotation per Minute (RPM). A higher RPM, more than 3000, translates to less human effort. Thirdly, your option should have a higher Impact per Minute (IPM). A higher IPM also translates to less effort. Lastly, you should use a wrench that is compact and lightweight. This will ensure flexible carrying and usage. If you are buying the tool to drive bolts and nuts, you’ll want an option that doesn’t require too much effort and one that is easy to operate.
Air Impact Wrench vs. Cordless Impact Wrench
There are physical and performance differences between the air impact wrench and the cordless impact wrench:
• The motor (brushless vs. non-brushless): Essentially, the motors of the cordless impact wrenches are brushless while the ones for the air impact wrenches are non-brushless (brushed). The brushed motor employs simple wiring for its performance and the working is facilitated by a switch. Due to their simplicity in design, these motors are not as effective as the brushless. The other demerit is that they have a shorter life. On the other hand, the cordless brushless motor enjoys a longer life and higher work efficiency.
• RPM, torque, and IPM: Air impact wrenches enjoy higher RPM, torque, and IPM than their cordless counterparts. The wrenches produce extra torque power, which translates to higher IPM and RPM. In the long run, you get to spend less energy in loosening tight nuts or bolts. They don’t have a limit on their working potential, and this means you can work with them continuously. Their power is derived from an external source (electric connection), and they work as long as there is electricity. On the other hand, the cordless impact wrenches are limited in power. They generate less torque if compared to the air impact wrenches, and their batteries only run for limited minutes before you charge them. This means that their functionality is battery-dependent.
• Drive (1/4, 3/8, or ½ inches: which one and why?): The drive size aids in the torque performance that is offered by the impact wrench. The cordless impact wrench comes with an adjustable power control feature, which makes it easy for you to change the torque rate when using it. Since the higher the drive size, the higher the torque, you should go for the ½” drive over the other two. However, when it comes to choosing between the 3/8″ drive and ¼” drive, you should go for the former. Unfortunately, a majority of the air impact wrenches do not have the adjustable features. Therefore, it’s hard to control the drive size. If you try to adjust the drive, you may break the bolt or nut that you are working on.
• The battery: A majority of cordless impact wrenches allow the swapping of their batteries since it’s external. You can have several power tools awaiting you to swap their batteries. This is effective in reducing clutter around your garage. As for the air impact wrenches, the batteries are inbuilt, and you don’t have the freedom to swap them. This is because the wrenches purely depend on their designer batteries. The batteries are mostly lithium-ion. This means that you are limited to use a specific battery. This is meant to help you avoid battery issues such as leakages and overcharging. However, in terms of battery performance, the cordless wrench requires frequent charging since their batteries lose charge faster.
What’s the Primary Use of an Impact Wrench?
Most people do not understand the basic uses of the impact wrenches. Their applications are:
• Used in construction sites and in a Mechanics garage: They help to put up massive pillars that are supported by bolts and nuts. The wrench drives and tightens the bolts and nuts securely.
• Used in home fixing: You can secure your furniture pieces or your kid’s bike using the wrench. The impact wrench torques through sticky bolts with ease, and thus great for home repair works.
• Car repair: If you find it difficult to change your car’s tire with your regular wrench, you can use the impact wrench. The tool is a fast, and it will help you tighten the bolts or nuts securely.
• Used in auto-mechanic shops: The store owners use these wrenches in performing heavy mechanical duties.
1. What’s the difference between NiCad and lithium batteries?
In terms of age, the nickel cadmium (NiCad) batteries are the oldest batteries employed in the impact wrenches. They are robust, cheap, and enjoy a longer shelf life. They are still common today, but their popularity has been overshadowed by the lithium-ion batteries. The lithium batteries employ the latest technology, and this is why they have managed to outperform the NiCad. Though expensive, the lithium-ion batteries are designed to withstand a majority of charging problems, and they are able to keep the charge for extended periods. The other difference is that they are lightweight, and thus great for the modern compact wrenches. If taken care of properly, the lithium-batteries can give you a longer service.
2. Which drill voltage should I choose? 18V, 20V, or 36V?
Basically, the higher the drill voltage, the more powerful the cordless impact wrench is. However, the choice of the voltage to use depends on the type of drilling job that you are doing. For light duties, you can use a drill voltage of 18V while for medium duties, you can use 20V. However, if you are looking to perform heavy drilling or driving duties, you can use a voltage that is as high as 36V. So, the decision on what voltage suits your cordless wrench is dependent on the intensity of work. To some extent, it also depends on the model of the impact wrench that you are using. A good wrench should allow the application of variable voltages depending on the type of work you are doing.
3. What does the “Ah” mean in cordless batteries?
Normally, the rechargeable batteries lose their power/charge when they are not in use. There are models that lose their power faster than others. The capacity of the cordless battery is expressed as Ah (Amperage hours). Typically, the Ah value expresses the amount of energy (charge) that the cordless battery holds. On a basic level, the higher the Ah value, the longer the battery stays with the charge, and the longer its used by the cordless wrench. As a buyer, it’s thus smarter to consider a cordless battery that has a higher Ah, and you can tell this from the cordless impact wrench reviews online.
4. What does Variable Trigger Speed Trigger mean?
Variable Trigger Speed refers to the ability to reverse the rotational movement of the cordless impact wrench motor. What you manipulate is the speed switch of the power tool. Once you have engaged the switch, it communicates to the other parts of the mortar, resulting in an opposite movement. Generally, a great impact wreath should allow you to change the trigger speed and achieve a great performance in as far as tightening/loosening the bolts/nuts are concerned.
5. What’s the difference between an air impact wrench and an air ratchet wrench?
The impact wrenches are essentially designed to give you a higher torque value than the air ratchet wrench. Usually, the impact wrench gives about 180 pound-feet while the ratchet gives you about 70 pound-feet. You will find it easy to use the impact wrench than the air ratchet. This is primarily because of their twisting capability. When you loosen the nuts, you will find it easy as the wrenches enjoy a higher torque value. As for the impact ratchets, they are ideal for loosening and tightening low and medium bolts. If you use the impact wrench here, it may break the bolts heads or damage the threads.
6. What’s the difference between RPM, IPM, and torque?
RPM stands Revolutions/Rotations per Minute. This is the speed at which the wrench is working under. IPM stands for Impact per Minute, and it defines the work performance of the wrench per given time. Torque refers to the force that the wrench is using. When the torque is higher, this means that the RPM and IPM are equally high.
As a smart buyer, you need the right guide to benefit from the best cordless impact wrench for the money spent. With the right tool, you will be able to perform your DIY duties efficiently. You will be able to loosen and tighten the nuts and perform drilling duties fast and efficiently.
