Factors to Consider When Purchasing the Best Cordless Impact Wrenches
When shopping for the cordless impact wrench, here are some of the things that you should consider.
1. Batter life
Since these are wireless impact wrenches, the battery power may limit you regarding run-times. The battery life can significantly change your usage time. It should not be a problem if you change one set of tires on the weekend. Nonetheless, a professional mechanic should purchase more than one battery pack or use at least a 20V impact wrench.
Some manufacturers sell more than one in the package, which is handy since you can use one battery while charging the other and switching when it is dead. Furthermore, since the lithium-ion batteries are removable, you can decide to get a bigger one. That way, it will last longer, but the weight will increase. Otherwise, you can try to find a third-party manufacturer that sells a compatible impact wrench kit.
2. Brushless vs. the brushed motor
Brushless motors don’t contain many moving parts as compared to brushed motors. The fact is, moving parts lead to friction, and friction causes a loss of effectiveness. Therefore, cordless impact wrenches with a brushless motor have some advantages over those with a brushed motor. These advantages include higher engine speeds, less maintenance, a greater power-to-weight ratio, and a longer life span.
However, all these advantages have a cost. Cordless impact wrenches with brushless motors tend to be more expensive because of more advanced technology and superior features. Besides, they require less maintenance and tend to last longer, so the extra cost might well is worth it at last.
3. Torque, IPM, and RPM
These are the three main factors that determine an impact wrench’s power. Torque is the amount of rotating power an impact wrench has; therefore, an impact wrench with the highest torque will have the most power and best performance.
IPM and RPM are also factors worth your consideration. IPM signifies the number of impacts from the ‘hammer’ generated per minute- impacts per minute. RPM signifies how fast an impact wrench can drive your fasteners- revolutions per minute.
4. Drive size
Each socket is comprised of two main parts; the socket head and the drive socket. The socket head is the part into which a bolt and nut fit, while the drive socket is the component attached to the wrench. Cordless impact wrenches’ drives are based on the size of their anvil input shaft that the socket fits. Conversely, impact wrenches’ drive size states the size of the sockets it can use.
Cordless impact wrenches come in sizes from ¼ inch to 1inch, with every size having its set of pros and cons. Facts are the larger the impact wrench’s drive size, the more powerful the impact wrench. Conversely, wrenches with large drive sizes will be bulkier and larger, and more difficult to fit into tight spaces. Use a 1/2 -inch drive for any general-purpose use because it is more versatile, allowing it to accomplish several tasks.
5. Sound and vibration
Don’t conclude that an impact wrench with more power is always better in every way than one with less power. When it comes to cordless impact wrenches’ power, there is an increased sound and vibration. Even though battery-powered impact wrenches don’t cause as much vibration and sound as their pneumatic complements, both types of impact wrenches are famous for causing ear and hand fatigue. If you are exposed to one of them for too long, the vibration and sound can damage these areas.
Luckily, many cordless wrenches feature vibration-reducing ergonomic handles to cushion the impact of excessive vibrations on your hands. Moreover, many allow for adjustable torque levels, so you can limit your exposure to the loud high-torque setting to times when you need it. However, you should always wear hearing protection and take breaks when operating it regardless of the noise and vibration reduction features.
Cordless impact wrench models have two main grip styles: in-line grip and pistol grip. Pistol-grip handles look like the handle and trigger assembly of a normal pistol. These handle types are the most popular because they are comfortable gripping and creating less hand fatigue when working long.
In-line handles are long and slim, resembling a standard screwdriver. The trigger and handle are joined at the backside of the wrench. Moreover, the anvil on the body of the impact wrench. This type of handle is ideal for maneuvering in tight spaces where a pistol-grip wrench cannot fit.
7. Additional features
Some impact wrenches come with LED lights on the housing that help you see in front of the impact wrench. This feature is useful if you regularly work in a dim-lit area. Consider also how the speed of the shaft is controlled. Some models have a dedicated button with some speed options, while others have a pressure-sensitive trigger. In this case, it will depend on your personal preference.
Some impact wrench models are designed with casings that could protect them from dust and water. If you are working in a dusty location like an auto body repair shop, dust protection is worth considering.
8. Size and weight
Consider the weight when shopping for an impact wrench. When you work with a heavy wrench, your wrists will get tired faster. Although the impact wrenches on this article are used to remove lug nuts, you will use them for other jobs if you have any in your garage.
The size of the impact wrench plays a role in removing the nuts on your car tire; big impact wrenches are hard to maneuver into certain places. Unluckily, most powerful models come in bigger sizes.
