Cordless Impact Wrenches

From mid-torque to high-torque, Hilti has you covered

Gone are the days when the only way to get powerful torque output was to be tethered to a corded power tool. You and your team deserve the freedom that come with using Hilti cordless impact wrenches. 

As part of our new 22V Nuron cordless platform, you can get more done, reducing the need to stop and switch out batteries.

Features and Benefits

Nuron battery technology

The Nuron lithium-ion battery platform provides greater amount of run time per charge enabling improved productivity. Our fast chargers help you save time.

Built tough

Hilti customers know they can expect a longer life from our power tools. With the brushless motor and hog ring anvil in our impact wrenches, you can count on it. 

Help increase user comfort

These impact wrenches are shorter and lighter than their predecessor allowing for a more comfortable experience as you anchor and bolt all day.  

Speeding things up

Two speed settings on our impact wrenches allow for securing fasteners quicker and our LED light helps you get it done with precision. 

In a tight spot?

With versatility and comfort in mind, Hilti's engineers have decreased both the length and weight of our impact wrenches by 20%. The compact design of the SIW 6-22 and SIW 8-22 impact wrenches make them the right tool to get into tight spaces. Powered by the Nuron battery platform, these power tools have a variable speed trigger providing you with the choice of two speeds to help control torque. Our improved LED light enables a better view of your application.
