Benefits of Cordless Over Corded For Mechanics

The biggest benefit of owning the best cordless impact wrench for automotive work is the portability you receive. You can take this power tool with you anywhere, as long as the battery is charged.

There’s no reason to search for power outlets to get a job done. Plus, many power tools share batteries among a series, so you can purchase multiple tools that use the same battery.

The downside to having a cordless impact wrench is that the batteries need to be charged. If you run out of juice, you may have to wait to complete your job.


Features to Look for in Cordless Impact Wrenches

Torque

When you have to remove stuck or rusty bolts, you need plenty of torque. The best cordless electric impact wrench for automotive provides enough torque to unscrew the stuck bolts with ease. The higher the torque rating, the more expensive the cordless impact wrench will be. The average impact driver delivers about 125 foot-pounds of torque.

Drive Size

You can find a variety of drive sizes with the range of wrenches. The higher the drive size is, the more torque it will also contain. Because of this, the drive size also affects pricing. Look for the most popular options from 1/4", 3/8" and 1/2" to find the one that best suits your needs.

Battery Type & Life

With everything else compared equally, the more voltage you have, the more power you get. However, the 12V battery is more compact, making them perfect for smaller jobs. Additionally, you won’t find much difference in battery life or performance between the 18V and 20V batteries. You can also reference the amp hours of a battery, which refers to the amount of amps that can be continuously discharged per hour.

Grip

After holding your automotive torque wrench for any length of time, your hand can become cramped and sore. That’s why you want to look for the best 3/8” cordless impact wrench for automotive that also contains a comfortable grip. By spending a little extra for something geared toward the shape and needs of your hand, you ensure a seamless operation.

Power/Speed & Adjustment

The RPM shows the rotations per minute or speed of the impact wrench. This number reflects how fast the job can be done. Some models come with variable speed adjustments, which helps determine how fast you want the wrench to rotate. These models will cost extra but are more versatile.

Noise Levels

To get quiet impact wrenches for automotive, you must be willing to spend a little more. However, this small expense is worth it, considering how much the loud noise can hurt your ears over time. Additionally, if you are working in your home garage, no one else wants to hear your wrench all day.

Build Quality & Portability

You want a high-quality impact wrench, but you don’t want the materials to cause a heavier weight. After all, you aren’t going to want to lug around a heavy tool all day. In addition, you want to consider how compact the tool is, especially if you plan to take it on the go or use it in tight spots.

Price & Warranty

We all want to own the cheapest cordless impact wrench on the market, but these models don't always provide reliable results. Instead, aim to find a brand that offers a good mix of value and durability. To determine if the wrench will hold up, read the customer reviews, and examine the warranty.

People Also Ask (FAQs)

What’s the difference between impact drivers and impact wrenches?

As you look at power tools, you will want to understand the differences between an impact driver vs. impact wrench for automotive use. The impact wrench is going to be heavier and often creates more torque. It is used for fastening or loosening bolts. The impact driver, on the other hand, uses a hex drive and is made to drive screws.

What’s the difference between Lithium and NICAD batteries?

The lithium-ion battery is lighter and smaller than NiCad batteries. Plus, lithium-ion batteries have virtually no self-discharge, which does make them more expensive. Most power tools with brushless motors work better with lithium-ion batteries.

What's the difference between torque, RPM, and IPM?

Torque refers to the rotational effort of a tool, while RPM stands for revolutions per minute. The RPM shows how many turns something will make per minute. IPM, on the other hand, stands for inch per minute when related to speed and capacity.

How do I care for my tool after use?

With the proper power tool maintenance, you can ensure that your wrench lasts as long as possible. Make sure you keep the tool clean and store them in an area that’s free of dust or moisture. You might consider purchasing the best rolling tool chest to keep your wrenches protected. Additionally, you should regularly inspect the tool and lubricate the moving parts as needed. When your power tool isn’t in use, place the battery on the charger to ensure it’s ready.
