Makita XWT12ZB – Ultra-compact

Makita XWT12ZB

  • Ultra-compact, lightweight, and comfortable to hold
  • Feature dual LED lights to improve your visibility in dark areas
  • Batteries are protected from overheating
  • Automatically stop rotation when “feeling” the fasteners loosen up enough


  • Deliver fewer speed settings
  • Not suit for heavy-duty tasks

The Makita XWT12ZB, with an emphasis more “adorable” end of the spectrum, becomes the most compact 3/8” cordless impact wrench in this list.

Most‌ ‌Powerful‌ ‌Cordless‌ ‌Impact‌ Wrenches‌


When you’re into the market searching for a cordless impact wrench, there will be thousands of results with numerous sizes and shapes. But what you actually have to focus on is its grip and hand-feel.

“Comfort” and “a good grip” are what you should bear in mind. Pay attention to the rubberized surface: Is it supportive for you to orient the tool with ease and control?

And the trigger placement: Is it located in a place within the reach of your hand?

This term tells you about the amount of turning force that your cordless impact wrench supplies.

Its measuring unit is foot-pound (or ft-lbs.)

The higher the torque, the harder tasks it can do, so we would say this feature is dependent on your power needs. Here are some clues to give you an idea of how much torque to opt for:

To remove the crankshaft of an engine, an impact wrench should feature 1,100 ft-lbs. of torque while for removing an Axle or changing a car tire, the range of 300 to 600 ft-lbs. is fine.

FAQs‌ ‌

Most‌ ‌Powerful‌ ‌Cordless‌ ‌Impact‌ Wrenches‌

How‌ ‌much‌ ‌torque‌ ‌do‌ ‌I‌ ‌need‌ ‌for‌ ‌an‌ ‌impact‌ ‌wrench?‌ ‌

The choice of torque is dependent on the application. Different application results on different torque requirements.



Install & remove the rims75 – 100
Repair the greenhouses from plastic100 – 150
Rail constructions450 – 750
Tighten large-sized fasteners200 – 1650

Should‌ ‌you‌ ‌use‌ ‌an‌ ‌impact‌ ‌wrench‌ ‌to‌ ‌tighten‌ ‌lug‌ ‌nuts?‌ ‌

No, you shouldn’t because it’s very easy to over-torque them, which takes risk of accidents. Instead, use a ratchet and then finish up with a torque wrench.

Can‌ ‌I‌ ‌use‌ ‌chrome‌ ‌sockets‌ ‌on‌ ‌impact‌ ‌wrench?‌ ‌

No, you can’t.

As chrome sockets are too hard to warp when being impacted, using them on an impact wrench is prone to cause serious damage to its anvil head.

What‌ ‌is‌ ‌the‌ ‌difference‌ ‌between‌ ‌regular‌ ‌sockets‌ ‌and‌ ‌impact‌ ‌sockets?‌ ‌

There are 4 basic differences between these two types of sockets:

Color: This is the feature that helps you quickly distinguish regular sockets from impact sockets (typically black) in a toolbox.

Locking pins: Only the impact sockets come with a grooved ring one their drive socket end to enable a locking pin

Usage: Impact sockets are specifically designed to cope with the vibration caused by drivers or impact wrenches so they suit only for these two tools. The regular sockets meanwhile can fit with various ¼”, 3/8”, and ¾” ratchets.

Materials: Impact sockets are crafted from chrome molybdenum whereas regular sockets are from chrome vanadium.

Can‌ ‌impact‌ ‌driver‌ ‌be‌ ‌used‌ ‌as‌ ‌impact‌ ‌wrench?‌ ‌

Yes, it can.

As an impact drive can do both carpenter and mechanic jobs, it’s possible to be used as an impact wrench. For example, you can use an impact driver to screw in lug nuts and bolts as long as there are proper bit and attachment.

Can‌ ‌I‌ ‌use‌ ‌a‌ ‌hammer‌ ‌drill‌ ‌as‌ ‌an‌ ‌impact‌ ‌wrench?‌ ‌

No, you can’t.

As these two tools are different in purpose, you can’t use a hammer drill as an impact wrench.

A hammer drill is designed for drilling into concrete, brick and other hard surfaces while an impact wrench is limited to fastening or loosening nuts and removing screws.


Any cursory glance around the web could make you drown in a bunch of options. As narrowing down the field and picking the most powerful cordless impact wrench that suits you is struggling, allow our thorough advice and intensive testing to help you is the best way.
