How Are Impact Drivers And Impact Wrenches Different
There are two significant differences between impact drivers and impact wrenches.
The first one is what you attached to these tools.
When using an impact driver, you screw and unscrew screws utilizing the tools chuck and impact driver bits.
Now, regarding impact wrenches, they have hog ring anvils to which sockets are attached so that nuts and bolts may be tightened and loosened
The second difference resides in the level of power both these tools provide.
With an impact driver, youre dealing with considerably less powerful motors and produce much less torque than with an impact wrench.
Generally, most impact drivers may be found with torque ratings between 1,500 and 1,600 inches per pound . On the other hand, its very easy to find cordless impact wrenches with a minimum torque of 200 ft/lbs.

Electronic Assistance And Smart Controls
Assist modes and smart controls are highly valued features for impact wrenches. Many fasteners have a torque rating and its easy to over-torque them if youre not careful. Having an automatic stop helps you run a nut or bolt quickly and still leave it short to finish off with a torque wrench.
In reverse, auto modes can back off a fastener and stop or slow down significantly so you dont run it completely off. When youre working at height or just hate chasing rogue nuts and bolts, its incredibly helpful.
Smart controls such as Milwaukee One-Key, DeWalts Tool Connect, and Bosch Connected tools have added benefits. Inventory management and tracking are the major highlights, but theres a lot more inside the apps that are worth considering.

Whats The Best Voltage For A 1/2 Cordless Impact Wrench

It all depends on what youre looking for.
With the more voltage you get in your cordless impact wrench, the higher torque youll enjoy if the motor allows it.
So, if youre the kind of mechanic that needs higher levels of nut-busting torque to remove difficult nuts and bolts, then you should get a cordless impact wrench with at least 25 volts.
A 1/2-inch cordless impact wrench with a 20-volt battery, on the other hand, is more than enough for most job sites as it draws sufficient torque.
Again, as I said earlier, itll be determined by your specific power needs.

Batteries: Volts And Amp Hours
All things being equal, higher voltage will give you more powerbut there are cases for lower voltage. With smaller batteries, 12-volt impact wrenches are more compact. This makes them good for smaller jobs, working overhead, or getting into tight spaces. Tools with 18 and 20 volts have less difference between them. Generally, 18-volt tools with advanced features and capabilities make them more versatile and easier to use.
Amp hours equals the number of amps that the battery will discharge, continuously, for an hour. Think of amp hours like the volume of a gas tanka bigger number equals more gas.

How Are Air Impact Wrenches And A 1/2 Cordless Impact Wrenches Different
Well, the most significant difference between these two is, of course, how they are powered.
Air tanks provide the power for air impact wrenches.
One of their benefits is that they have more torque and are less costly to get and maintain since their internal components are not pricey due to their engineering simplicity.
However, air tanks and air compressors are needed to power this tool, which means a significant upfront cost for customers seeking inexpensive impact wrenches.
On the other hand, Cordless impact wrenches are more costly as a tool on their own because of the complex internal parts that allow them to work without any external power supply.
They do provide a solid level of torque and benefit from not being connected to any external air tank, which is extremely handy since you wont have to deal with hoses.
On the other hand, because of the large number of internal components, they may fail and cost you the money you didnt want to spend on costly replacement parts or even on replacing the whole tool.
