Bosch Professional 0601390908 Review

Not every fastening job happens out in the open where a full-sized drill fits comfortably. Plumbers, electricians, kitchen fitters, and automotive technicians regularly face the frustration of trying to drive a screw in a space so tight that a standard drill simply will not fit — think behind a sink, inside an electrical cabinet, between engine components, or under a worktop overhang. This is where a cordless angle screwdriver proves its worth. With a head set at 90 degrees to the body, these compact tools slip into gaps that would defeat any conventional drill, letting you drive screws and even drill small holes without contorting your wrist or dismantling surrounding fixtures. A good angle screwdriver combines a slim profile, enough torque for real fastening work, and a lightweight body that you can use one-handed all day. It may not replace your main drill, but when space is tight, it is the tool you reach for — and it saves you time, strain, and stripped screw heads every single time.

Selecting the right angle screwdriver comes down to a few practical considerations. First, check the head length — the distance from the bit holder to the back of the angled gear housing — because a shorter head fits into narrower gaps. Torque matters too, but differently than with a standard drill: 10 to 15 Newton metres is ample for driving screws up to 6 or 8 mm in softwood and sheet metal, which covers most real-world tight-space tasks. Voltage and battery capacity determine weight and runtime; 12V systems hit the sweet spot for one-handed use without sacrificing too much power. Look for a metal gear housing — it dissipates heat better than plastic and stands up to the occasional knock against a joist or chassis rail. Finally, consider whether the kit includes two batteries, because swapping to a fresh pack mid-task keeps you moving without waiting for a recharge.

This review examines a 12V cordless angle screwdriver from Bosch Professional, supplied with two 2.0 Ah batteries, a fast charger, and an L-BOXX carry case. We assess its access capabilities, real-world driving performance, build quality, and whether its compact design and dual-battery kit justify the investment for professionals who regularly work in confined spaces.

The GWB 12V-10 is a dedicated angle screwdriver running on Bosch's 12V Professional battery platform. It produces 11 Newton metres of maximum torque, which is well-matched to its intended role of driving screws and running small drill bits in spaces where a bigger tool cannot go. The motor spins at up to 1,300 revolutions per minute, and the 10 mm keyless chuck accepts standard hex-shank driver bits and small drill bits up to 10 mm diameter. Drilling capacity is rated at 10 mm in both wood and metal — enough for pilot holes, cable entry points, and light fabrication work. Two 12V 2.0 amp-hour batteries come in the box, along with a GAL 12V-40 fast charger that tops up a depleted battery in well under an hour. At just 0.9 kilograms without battery, the tool is genuinely featherweight, making overhead and extended one-handed use comfortable rather than punishing.

The defining design feature is the right-angle gear head, which positions the bit at 90 degrees to the tool body. This configuration dramatically reduces the overall height needed to engage a fastener — where a standard drill might need 250 mm or more of clearance behind the bit, the GWB 12V-10 needs only the depth of its angled head, which measures well under 100 mm. The gear housing is metal rather than plastic, improving heat dissipation during prolonged use and adding structural rigidity that translates to less bit wobble. A forward/reverse switch is positioned for thumb operation, and the slim, cylindrical body — only slightly thicker than the battery at its base — is easy to grip in various orientations. The Bosch Professional blue finish and rubberised grip panels signal its trade-focused positioning.

In practice, the GWB 12V-10 excels at the awkward jobs. Driving screws into the underside of kitchen wall units, fastening brackets inside server racks, assembling flat-pack furniture in corners with limited clearance, and working on vehicle interiors where the dashboard or seat rails block access are all tasks where this tool transforms a wrestling match into a quick, straightforward operation. The two-direction rotation is a simple but essential feature — without it, removing screws would be impossible in many confined positions. The variable-speed trigger provides decent control, though it is less nuanced than the multi-speed dials found on larger drill-drivers. The electronic motor protection guards against overload, which is reassuring when the bit encounters unexpected resistance in a blind screw hole.

The kit includes two 2.0 Ah batteries, which is a practical touch. While these are not the highest-capacity packs in Bosch's 12V range, having two means you can keep one on the charger while using the other, effectively achieving continuous runtime for most jobs. The GAL 12V-40 fast charger refills a battery in approximately 40 minutes. An L-BOXX carry case is also included, complete with a half-height insert tray (the 'shimming' referred to in the product name) that can hold a selection of driver bits and small accessories. As with all L-BOXX cases, it stacks securely with other Bosch cases for organised transport and storage. A belt clip would have been a welcome addition for hands-free carry between tasks, but none is included in this kit.

The tool itself is compact — the L-BOXX packaging measures 44 × 35.5 × 12 centimetres, but the screwdriver body is considerably smaller, making it easy to slip into a tool bag or even a deep pocket on work trousers. The kit weighs approximately 0.9 kilograms for the bare tool, rising modestly with the 2.0 Ah battery fitted. On Amazon France, it holds a rating of 4.4 out of 5 stars from 97 customer reviews and ranks 219th in the Drill Drivers category. The product carries the EAN 03165140730846. While the product details indicate no warranty is provided, Bosch Professional tools typically come with a three-year warranty when registered through their online portal — it is worth checking with the seller. The tool is manufactured in Malaysia to Bosch's global standards.

This compact 12V angle screwdriver is purpose-built for professionals who regularly need to drive screws and drill small holes in confined spaces — kitchen fitters, electricians, plumbers, automotive technicians, and furniture assemblers will find it earns its place in the tool bag on day one.
