The Bosch Professional GSB 18V-55 impact drill driver is more or less the equivalent brushless of the GSB 18V-21. A difference which is found both in the price of the machine and in its performance.
Efficiency in all areas, that’s what the Bosch Professional GSB 18V-55 impact drill driver offers. Engine brushless of this cordless tool overall provides excellent work and offers versatility. Greater autonomy would have allowed him to achieve perfection. But ultimately, the ProCore 18 V range from Bosch Pro has advantages that almost make up for its shortcomings.
Strong points
- Compact and well finished.
- Full metal chuck.
- Good at drilling and screwdriving.
- Efficient LED lighting.
- Getting started.
- Fast charging.
- Inverter precision.
Weak points
NB: The reported price drop is calculated by comparing the lowest price of the day with the average of the lowest prices charged by all merchants for the product last month, with security rules to exclude the prices of stores whose the VAT policy is not clear (so-called “gray” stores, typically in the case of imports from China).
Alternatively
The BL188 impact drill driver from Black+Decker is very efficient overall. It constitutes a first-class screwdriver and a satisfactory drill, especially in masonry. It’s a shame that the finishes weren’t a little more careful, because that would have made it an ideal machine.
