Factors To Consider Before Buying Impact Wrench
Battery Life: The Heart of Cordless Impact Wrenches
The performance of cordless impact wrenches is heavily influenced by their battery life. Modern impact wrenches come with various battery options, such as 12-volt, 18-volt, and 20-volt, with higher Ah (ampere-hour) ratings indicating longer runtimes.
Brushed vs. Brushless Motor
When it comes to purchasing a cordless impact wrench, the first choice that you need to make is whether you are going to choose a brushed or a brushless motor. For the longest time, the only option was a motor with a brush. These older style electric motors required the replacement of their brushes after only 50 hours of use. However, the newer brushless motors use circuits and sensors to replace the need for a brush. As a result, not only are brushless impact wrenches able to provide more torque, but they are also able to last longer than those with a brush.
RPM
You will find that no two impact wrenches are the same, especially when it comes to the RPMs that the wrench is capable of spinning. There are a number of options available on the market that spin more than 3000 RPMs. However, it is important to remember that the higher the RPMs, the greater the torque. And while torque is an important factor when choosing an impact wrench, faster rotations mean less effort for the operator.
Torque
A cordless impact wrench is specifically designed to employ two forms of force in order to remove a nut or a bolt. The first force comes in the form of rotational torque. The greater the torque, the greater the twisting action. However, if you twist on a stubborn bolt too hard, you are bound to snap it in half. In order to prevent this, impact wrenches use an impacting force that helps to loosen up any stubborn nut or bolt. And, although there are a number of affordable wrenches available that are capable of producing around 50 ft-lbs. of torque, a good cordless impact wrench should produce anywhere from 125 to 250 ft-lbs. of torque.
IPM
Not all impact wrenches are created equal. While torque plays an important role in the proper operation of a cordless impact wrench, the IPM, or impacts per minute, plays an equally important role. When a nut or a bolt is very tight or even rusted, the ability to remove it comes down to how many impacts or beats per minute the wrench has. The faster the IPM, the greater the contact between the socket and the bolt. However, caution should be taken because as the IPM increases, the RPM will decrease. It’s important to make sure that you find a good balance between the impacts per minute and the revolutions per minute.
Batteries
You can find cordless impact wrenches in a variety of different battery voltages and capacities. The smaller impact wrenches that are available today, are usually powered by a 12V battery. At the other end of the scale, you will find impact wrenches with batteries of 18V or more. While these units will weigh more, they are also able to produce a lot more torque than the 12V units. You will find that the larger battery voltages provide the highest torque ratings.
Runtime
The voltage of a battery is not the only important factor when choosing a cordless impact wrench. The other factor is the overall capacity of the battery itself. Batteries are rated in what is known as amp-hours, and this rating refers to how many amps the battery can discharge over the course of an hour. Just like a gas tank, the higher the (Ah) rating, the longer the battery can last between charges.
Weight
Pneumatic impact wrenches can get pretty heavy simply because they are made almost entirely out of metal. But a cordless impact wrench, on the other hand, is made of a mixture of materials that results in a lighter weight. The biggest factor to take into consideration when it comes to the weight of a cordless impact wrench is the size of the battery. The larger the battery, the heavier the wrench will weigh. As result, it is important to balance the battery’s capacity and weight when making a final decision.
