Ask any mechanic who has dealt with broken air lines and they'll tell you that there is nothing better than having a good backup impact wrench that is not dependent on the air compressor. Impact tools, whether air powered or electric, have helped mechanics remove and replace mechanical components quickly for many years. However, if you're on the road and don't have access to your compressor, having a dependable electrically-powered cordless impact gun can save you time, money, and provide better service to your customers.
Why is an electric impact gun beneficial for a mobile mechanic?
When you work on the road, it's extremely difficult to lug around an air compressor. Even if it's small and fits easily into your truck, the reality is that most air impact wrenches rely on having an endless supply of air that typically comes with an industrial sized compressor. This is why most mobile mechanics, and even in-house shop mechanics, utilize cordless impact guns while they are working on vehicles.
A cordless impact gun is extremely beneficial to any mechanic for multiple reasons, including:
Gives the mechanic the flexibility to use it in close quarters without the air cord being in the way
Can use the cordless impact gun inside vehicles without the air hose getting pinched
No threat of air lines becoming disconnected or breaking
No need for air extension lines that are trip hazards in any automotive shop
What type of electric impact gun should a mobile mechanic utilize?
In regards to electric, cordless impact guns, size really does matter. Most impact wrenches are designed to use ½" drive sockets; however, these tools are also beneficial for ?” and ¼" sockets as well. Instead of having three separate electric impact wrenches, they'll start with a 20v, ½" drive electric impact wrench and use adapters to downsize to smaller drives if needed.
Most tool manufacturers, like Mac Tools for example, sell a 20 volt cordless impact wrench in a kit that includes multiple attachments and features including:
Strong and durable nylon body that is able to withstand the application of automotive fluids without damaging the impact wrench
Variable-speed trigger that gives the mechanic better control and versatility of the impact wrench. This is especially critical for mobile mechanics as they can't afford to strip bolts or nuts while providing service to a customer on site.
½" drive anvil with a hog ring attachment that allows for quick and simple socket changes
Anti-marring bumpers on all sides of the impact wrench to protect it if dropped or frequently laying it down
A strong and durable, brushless motor that will increase the longevity of the tool
R-Spec battery that delivers optimal durability and performance (with a spare and charger included in the kit)
A high-quality contractor bag that will easily carry the impact wrench, spare battery, charger, socket sets and extensions
It's no surprise that most mobile mechanics see the value of investing in a high-quality impact wrench that's portable, even when they have on board air compressors on their trucks. Every mechanic understands the value of having spare tools, as their customers can't accept excuses that their tools broke.
