Find The Best Cordless Impact Wrench For The Money

More and more professional mechanics as well as hobby mechanics are shifting their loyalty to the cordless impact wrench (CIW). You might be wondering why you need to purchase this tool, as you already possess a cordless drill. There are several differences between them. Whereas the drill creates an in line torque, the wrench creates rotational torque with an internal spring loaded and pulsating cam. This creates the impact force required to loosen a rusty nut. The effect of this tool is similar to banging a wrench with a hammer to loosen rusty nuts, but completes the job faster. Apart from this, the CIW does not have reactionary torque. Therefore, you do not have to use brute force to prevent the drill from rotating in the opposite direction in your hand. Find below details of several models that will help you determine the best cordless impact wrench for your requirements.

While the batteries charge quickly, they drain out quickly too. This can be frustrating while doing a big job, as one has to replace the batteries every 30 minutes. Although the tool itself does not have a magnetic bit holder, the manufacturer has included a belt loop for keeping attachments and bits. The included variable speed trigger allowed me to control both the IPM and the RPM. The tool is light in weight... six pounds along with the batteries.

The light weight of the tool and its compact design allows me to work effortlessly in tighter work spaces. Socket changing was a piece of cake, thanks to the included hog ring anvil. Although the description states one battery, the tool I received contained two 4.0 Ah Li-Ion batteries. This is arguably the best 3/8 cordless impact wrench I have come across.

6. Makita XWT041X 3.0Ah 18V LXT Lithium-Ion Cordless 1/2" Square Drive Impact Wrench Kit

The kit includes the impact wrench, one 18 Volt LXT Li-Ion 3.0 Ah battery, and a charger. However, one can purchase the tool itself without the accessories for a lower price. This tool has sufficient torque for a wide range of loosening and fastening jobs. Although the batteries included charge quickly, you have to purchase an additional battery, as the unit contains only a single battery. The design of the tool is ergonomic and compact.



Pros Cons
  • Three years limited warranty
  • Light in weight
  • Extremely powerful
  • Amazing battery life

  • Unit ships with a single battery - you're definitely going to need two batteries.

A: Yes, you can.

Q: Country of manufacture
A: Made in China

Q: Does the tool include a case?
A: No, it does not

My overall view

I am extremely confused about the country of origin. Some people say that their unit had a sticker with the words "Made in Japan," whereas other said that the label on their unit stated "Made in China." I loved the shock absorbent handle and the rubberized soft grip handle, but was annoyed when the batteries dropped out several times while using the unit. Measuring 10.5", this compact tool provides 325 ft-lbs of max torque. At 2,200 IMP and 1,600 RPM, this tool has lots of superior fastening power. I strongly recommend it.

Bosch is renowned all over the world for their mechanical and electro-mechanical products. Therefore, there is no reason to be surprised by the outstanding performance of their IWH181-01. The short head length and light weight allows one to use it for extended periods without any fatigue. Its spring load anvil and hammer generates high amount of torque. This beauty works equally well with Fatpack or Slimpack batteries. The manufacturers have impressed clients with the hard case socket storage.
