The Bosch GSR 18V-90 C is a professional-grade cordless drill driver designed for demanding tasks, featuring a compact form factor that excels in tight spaces. Reviewers praised its robust build quality, including a metal chuck and soft-grip handle, along with its brushless motor that delivers 64 Nm of torque. The precision clutch and kickback control are highlighted as standout safety and performance features. However, it lacks hammer functionality for masonry work and comes with a premium price tag of €170. While ideal for professionals and serious DIY enthusiasts, those needing masonry capabilities should consider alternatives like the GSB version.

Full review
A 163mm nose that fits inside a cabinet carcass
The GSR's selling point is length. A 163mm head lets it work inside a cabinet carcass or between joists where a full-size drill has to be angled in and fudged. At 1.95 pounds bare it is light enough to hold overhead through a run of screws without the wrist complaining, and the soft-grip handle and balance are what reviewers single out after extended sessions rather than any headline number.
64 Nm on the low gear, 2,100 rpm on the high
Two gears cover the range: a low gear topping out around 600 rpm that delivers the full 64 Nm, and a high gear to 2,100 rpm at 36 Nm for drilling. That is a lot of torque for a compact 18-volt driver, and the brushless motor holds it under load rather than sagging the way a brushed motor does as the pack drains. The kit ships with a 2 Ah battery, which suits the tool's size and runs down quickly on heavy work.
A 13mm metal chuck and twenty clutch settings
The 13mm keyless chuck is metal rather than plastic, which is the clearest durability difference between this and budget drills: plastic chucks develop runout and eventually stop gripping round-shank bits properly. Twenty clutch positions give fine enough control to seat screws in softwood or in hardware without stripping the heads, and that is most of what a driver is actually asked to do day to day.
Kickback control catches a bind-up before your wrist does
Kickback control is the feature worth knowing about. If the bit binds and the body starts to rotate, the tool cuts power before the handle can twist out of your hand. On a hole saw or a large spade bit in a drill this compact that is a real safety benefit rather than a marketing line, because there is not much mass to absorb the reaction.
No hammer mode, and lag screws stall it
There is no hammer function, so masonry needs the GSB version or a separate SDS drill entirely. And for all the torque on paper, reviewers agree it stalls before driving a long lag screw fully home in dense timber. This is a cabinet, fixings and general-DIY drill, not a framing tool, and anyone whose work is mostly large fasteners should buy something heavier and accept the extra bulk.
Strengths
- +Compact design with 163mm head length for tight space maneuvering
- +Brushless motor offering improved efficiency, durability, and longer lifespan
- +Metal chuck provides superior durability and secure grip compared to plastic alternatives
- +Precision clutch enables accurate torque control to prevent overdriving screws
- +Kickback control reduces risk of sudden torque reactions during bind-up scenarios
Watch-outs
- −Not suitable for masonry work without hammer functionality
- −Higher price point at €170 for the bare tool
How it compares
The Bosch 18V Cordless Compact Drill/Driver is more powerful and durable than the Milwaukee M12 FUEL or Ryobi ONE+, but it's more expensive and lacks hammer functionality compared to the Makita 18V LXT or DEWALT 20V MAX XR. It's not as compact as the Bosch 12V Max, but it offers superior torque and safety features.
