Bosch GDS 250-LI Cordless Impact Wrench Mall+254

Bosch GDS 250-LI Cordless Impact Wrench employs the less-efficient brushed motors in order to keep the price down. Typically, power tools with brushed motors are also some 30% less efficient versus their brushless counterparts. In some instances, brushed motors such as the one used in the GBH 180-LI rotary hammer, will bog down under heavy load when used with a lower amp-hour battery pack.

GDS 250-LI wrench is equipped with an Auto Bolt Release (ABR) function via a button at the base of the unit. When enabled, the ABR automatically stop the tool once the bolt is impacted-free and preventing the bolt (or nut) from flying out of the socket as the impact driver free-spins to its 2,400rpm max speed. While this might be a minor annoyance when you’re on the ground changing out your car tires, it can have devastating consequences when it falls off a scaffolding.

Bosch GDS 250-LI Cordless Impact Wrench when paired with a 1.5Ah pack, the GDS 250-LI was used to loosen a 27mm front sprocket nut from a Kawasaki ER-6n that was torqued down to the manufacturer’s specified 125Nm. Even after 25 seconds, all the GDS 250-LI did was vibrate. When we swapped out the 1.5Ah pack for a 3.0Ah unit, the GDS 250-LI managed to break the nut loose but only after almost 20 seconds of continuous impacting.

GDS 250-LI has a claims a 3,300 beats per minute (bpm), typically, the higher the bpm, the smaller the hammer and the longer it would take to tighten or loosen a nut. A typical pneumatic impact wrench has an impact rate of around 1,200bpm. With the same token, the GDS 250-LI also feels very smooth during operation with minimal vibration.

Bosch GDS 250-LI can easily accomplish a majority of tasks required of a 1/2-inch impact wrench (within means, that is) but probably the most appealing factor is that the GDS 250-LI is priced to fit within one’s budget with a size that easily fits in your toolbox.
