What Makes the Bosch GDS18V-221 Impact Wrench Special?

The Bosch Core18V battery platform utilizes 21700 Li-ion cells, which provide more power from fewer cells than the 18650-celled packs that have become the industry standard.

The benefit here is an overall lighter tool that can still keep up with the demands of the job. The tool by itself only weighs just 2.77 lbs and the kitted 4.0 battery only adds another 1.15 lbs. And, with a 6.4 in. head length, this 1/2 in. square drive impact wrench stays compact for access to tighter spots.

The Bosch Impact Wrench features a brushless motor that produces up to 221 ft-lbs of torque, 3,400 no-load impacts per minute, and 2,400 RPM to fasten lag bolts, concrete anchors, and lug nuts quickly.

While smaller and faster than the Bosch IWBH182B, the GDS18V-221 also adds 1,000 in-lbs of torque. Of course, the Auto Bolt Release feature really sets the Bosch GDS18V-221 Impact Wrench apart. This feature stops the rotation of the drive shaft when the tool senses no resistance. This keeps you from accidentally spinning off nuts during removal. This feature proves very helpful whenever you want to take off bolts without dropping them.

The GDS18V-221 also features a comfort grip that Bosch claims they’ve designed to help keep the head the tool cooler during use. An LED light will let you see what you’re doing, even in dimmer workspaces.
