High-Torque Performance
The Hilti SIW 10-22 3/4″ High-Torque Impact Wrench isn’t adorned with fancy controls or features. However, it’s a straight forward powerhouse for really difficult fastening applications. The combination of the robust brushless motor and the new NURON battery platform result in one of the most powerful cordless 3/4″ impact wrenches.
Sending tools to the fleet mechanic in the quarry usually results in a short life. The environment and shear size of the equipment makes it the perfect testing location for high capacity tools like the Hilti SIW 10-22 Impact Wrench. One of the most impressive things about the SIW 10-22 is the nut busting capability of this wrench. It can break free many bolted connections that some 1″ cordless impact wrenches can’t do.
It’s so powerful that it will break fasteners. Hilti publishes a warning on their site stating that there is a risk of over-tightening and damaging fasteners. This impact wrench broke off several 5/8″ fasteners with very little effort, therefore users should be careful on small fastener applications.
The SIW 10-22 doesn’t have many features which is refreshing with an impact wrench. The SIW 10-22 has a well placed LED light just above the battery that provides good light for the work surface. There is a simple switch to change between speed 1 and 2. It also has a simple green LED light to designate which gear its in.
For those that work at height and require a positive retention for sockets the SIW 10-22 has a through hole friction ring anvil. It’s a pretty simple system and works well.
Final Thoughts – Hilti SIW 10-22
The Hilti SIW 10-22 High-Torque 3/4″ Impact Wrench is outstanding. It’s built like a tank, it has very impressive torque, has a great price point, and it offers one of the best warranties on the market. This is an exceptional cordless impact wrench for steel erectors, fleet mechanics and anyone working with large diameter fasteners.
