Bosch GSR 18V-90 C Professional review: a compact brushless drill with smart safety

Bosch makes two families of power tools: green tools for home DIY and blue Bosch Professional tools for trades. The GSR 18V-90 C sits in the blue range as a compact brushless drill driver. It is designed for drilling wood and metal and driving screws all day, and it adds electronic safety features you rarely find on cheaper drills.

This Bosch GSR 18V drill review is based on Bosch Professional's specifications, the official instruction manual and Bosch's published product data. It covers power, control features, battery options and connectivity, and helps you decide whether this drill or a different Bosch model suits you better.

Design and build

The GSR 18V-90 C uses Bosch's T-handle layout with a compact head length of 163 mm, which helps when working inside cabinets or between joists. It weighs 1.1 kg without a battery, so it stays manageable overhead. A belt clip, a work light and a small user interface on the body are included.

The 13 mm metal chuck is sturdier than the plastic chucks on many DIY drills and transfers torque well. Bosch sells the tool in several versions: bare in a carton, in an L-BOXX case, or as a kit with two 4.0 Ah batteries and a quick charger.

Power and performance

The brushless motor delivers 64 Nm of hard torque and 36 Nm of soft torque, with two gears: up to 630 rpm for driving and up to 2,100 rpm for drilling. Bosch rates it for holes up to 68 mm in wood and 13 mm in steel.

That is enough for most carpentry, fitting and installation work, including large-diameter wood bits and long screws. Brushless motors are also more efficient than brushed ones, which usually means more work per battery charge and less maintenance.

KickBack Control and Precision Clutch

These two features set this drill apart. Both can be switched on or off with buttons on the user interface, with LEDs showing their status.

• KickBack Control: if the bit jams and the tool starts to twist suddenly, the motor cuts out quickly to reduce the risk of wrist injury.
• Precision Clutch: an electronic clutch stops the motor once the preset torque is reached, reducing clutch wear and the ratcheting noise of mechanical clutches.
• Work light: helps in dim corners and cupboards.

Batteries and AMPShare compatibility

The drill works with all Bosch Professional 18V batteries and chargers, including the larger ProCORE18V packs. Bosch also lists it as compatible with AMPShare, the cross-brand battery alliance, which lets you share packs with tools from other member brands on the same platform.

If you already own Bosch Professional 18V batteries, the bare tool is the cheapest way in. If you are starting from scratch, the kit with two 4.0 Ah batteries is more convenient.

Connectivity: what the 'C' means

The C in the name refers to connectivity. According to the manual, fitting the optional Bluetooth Low Energy Module GCY 42 lets you register and personalise the tool, check its status and warnings, and adjust the work light brightness and the display backlight from a phone. The module is sold separately, and the drill works fully without it.

GSR vs GSB: which Bosch 18V drill do you need?

GSR is Bosch's code for a drill driver. GSB models add a hammer action for drilling into brick and masonry. If you need to put up shelves on brick walls, the GSB 18V-90 C is the better pick. If you work mainly with wood, metal and screws, the GSR does everything you need without the hammer mechanism. For occasional home use, Bosch's green UniversalDrill 18V costs much less.

Who should buy the Bosch GSR 18V-90 C?

This drill is aimed at carpenters, electricians, kitchen fitters and other trades who drive screws and drill wood or metal every day, as well as ambitious DIYers who want professional-grade kit. The safety features are especially helpful when using large bits that can bind. If you mainly hang pictures and assemble flat-pack furniture, the extra cost over a green Bosch DIY drill is hard to justify, and if you often drill into brick, pick the hammer-drill GSB version instead.

Frequently asked questions

The Bosch GSR 18V-90 C Professional is a compact, well-thought-out drill driver. Strong brushless power, a solid chuck and two smart safety features make it a pleasure for regular use, and the wide battery compatibility adds long-term value.
