Buyer’s Guide

How does a ½ Inch Cordless Impact Wrench work?

Cordless ½ impact wrenches are tools made for producing high-level of torque needed for removal of tight lug nuts. They work on batteries, meaning they are transportable tools that need batteries, where most of them operate on lithium batteries and need to be charged to work. The marking of ½ inches implies the socket size. These cordless wrenches are pistol shaped, where the motor creates energy thanks to the rotation, which is further pushed into an anvil. This creates a certain amount of torque which allows you to create a powerful impact on the targeted area, helping you secure or loosen lug nuts.

What to Pay Attention to When Choosing Your New ½ Inch Cordless Impact Wrench?

The highest torque the better, so go for models that promise the highest amount of deliverable torque. You will want a tool with a high number of impacts per minute and you should do well with any impact wrench that delivers around 3,000 ipm. When buying an ½ impact wrench ideally go for models that have few speeds, as this will allow you to work on a high variety of applications. Brushless motors are powerful and are probably the ideal choice, but don’t fret from other models as well, as long as these are powerful enough. Here is expert advice: ‘’Because these tools need batteries, you will need one that has a long battery life, especially if you continuously and frequently work outside’’.

How Should I Use a ½ Inch Cordless Impact Wrench?

Before you start working make sure you wear safety goggles and safety gloves as you will work with a very powerful tool. Once the battery is charged, the ½ inch impact wrench will be ready for use. Once the impact socket that suits the nut you want to tighten or loosen is tightly secured onto the body, which you do by pressing it onto the holder, simply place the socket onto the lug nut, hold it steady and press the trigger button in a few small measured sequences. Remember, to loosen the nut you will need to set the tool in reverse. Once the lug nut is loose enough, release the trigger button and you should be able to safely remove it.

What Design Specifications Should I Pay Attention to?

While not all plastic tools are essentially bad, avoid going for an impact wrench that has a motor housing made of plastic, as this will increase the risk of burning and overheating. Instead, opt for lightweight models made mostly out of meta parts. The handle should be easy to get a grip of and have a rubberized, non-slip layer on top of it. Look for impact wrenches that have LED light as this design element will make it easier to work in low light conditions and give you more precision when working. Although not a mandatory thing, if you want to have an all-in-one impact wrench set, go for items that come with a battery and a charger, so you have a full kit at your disposal.
