The Bosch GDS 18V1600 HC Cordless Impact Wrench is one of those rare tools that actually delivers what its spec sheet promises brute force and real jobsite muscle without being tethered by a cable.

Heres the thing: this isnt a toy attachment for DIY weekend jobs its a purposebuilt pro tool with Boschs BITURBO Brushless tech that begs for the biggest batteries you can throw at it, and it eats heavy steel work, pipe fitting, and construction hardware for breakfast with less drama than a smaller wrench.

Key Features:

• BITURBO Brushless Motor – Gives near cordedlike power and less wear, so you can push the tool hard without it whining for breath.
• Auto Bolt Release (ABR) – Stops bolts and nuts from dropping onto the ground when loosening real time saved on site.
• 3Speed / Torque Settings – Lets you dial power in for delicate jobs or go fullblitz on stubborn fasteners.
• ProCORE18V Battery Compatibility – Works with big Ah packs for long run times that matters when youre on a boom for hours.
• 3/4″ Square Drive – Standard heavyduty anvil size that mates with serious sockets and extension bars with ease.
