The Bosch GSB 12V-35 Professional cordless impact drill, 12 Volt, 2x Li-Ion battery 3.0 Ah, in L-Boxx, blue/black is an advanced and compact tool designed for users looking for a reliable tool for drilling and screwdriving in everyday and more demanding DIY projects. This model unleashes your creativity and provides exceptional flexibility - at home, in the workshop or in the field.

This model is ideal for consumers who expect the power of a professional tool in a small, lightweight format. Two high-performance 3.0 Ah Li-Ion batteries are included, so the project can proceed smoothly, without unnecessary interruptions for charging. The combination of impact drilling, screwdriving and drilling in various materials means versatility and always ready for a new task.

The tool stands out with its brushless motor, which delivers more power, a longer service life and less maintenance. A maximum torque of up to 40 Nm provides enough power for demanding screws, while the impact rate of up to 30,000/min makes it easy to work in hard materials such as concrete or brick. The high rotation speed of up to 2,000 rpm enables fast work progress, even when time is of the essence.

The tool is extremely comfortable to use when working; the modern ergonomic design allows for an excellent grip and minimal hand fatigue. Optimal protection against overload or overheating is also included, so you can use the tool to its full potential without worry. The L-Boxx system makes it easy to carry and store, which is important for efficiency and order in your tool collection.

With the innovative Professional series, Bosch has once again proven why you trust its technology: you get a tool that sets new standards among cordless impact drills with its power, durability and practicality.

It is important to know

Before choosing a cordless impact drill, it is crucial to consider what tasks you will perform most often and what environment you will use it in. Tools in this class offer a good balance between compactness, performance and flexibility for various everyday household tasks. Pay special attention to the relationship between maximum torque, number of batteries and actual needs for impact drilling.

• The model with two included batteries allows for uninterrupted work, which is a great advantage in practice for longer or larger projects at home or in the field.
• The compact dimensions and lighter design are useful when working in confined spaces or where handling larger tools is difficult.
• The maximum torque of up to 40 Nm is suitable for most household and light assembly work, but may have limitations with very demanding materials or larger drilling diameters.
• The impact mode makes drilling into masonry (brick, lighter concrete) easier, but it is not a replacement for heavier classic impact drills or hammers for really tough jobs.
• Lower battery voltage (12 V) means lower overall weight and a compact design, in exchange for slightly less power reserve for extremely demanding tasks.

In practice

🟢 Furniture assembly and everyday screwing

Very convenient – thanks to its compactness, good torque and two batteries, it is great for furniture assembly and routine household use.

🟢 Drilling and screwing in wood, plastic or lighter materials

Very suitable – benefit from good torque and operating comfort; also suitable for repetitive tasks or longer projects.

🟡 Drilling into masonry or harder materials

Suitable with limitations – the impact mode allows drilling into brick or lighter masonry, but for thicker or harder walls, expect less power than larger corded or more powerful cordless models.

🟢 Working in hard-to-reach or confined spaces

Very convenient – due to its small dimensions and weight, it is easy to handle even where space is limited.

🟡 Long-term or professional work with heavy workloads

Suitable with limitations – two batteries extend the working time, but due to the 12 V system, the power is reserved mainly for lighter and medium-demanding tasks.

Answers to frequently asked questions

Can I use the included batteries with other Bosch 12 V tools?

If you have other tools in the Bosch 12 V Professional series, the batteries are generally compatible across the entire system.

What does the maximum torque limit of 40 Nm actually mean?

For most household tasks and installations in wood, plastic or thinner materials, the torque is more than sufficient; however, in really hard materials or for larger screws, you may encounter the limit of performance.

How does impact mode work in practice when drilling into masonry?

The impact mode makes it easier to drill into brick or lighter masonry, but is not primary for frequent work in concrete or very hard surfaces.

What is the advantage of two batteries in everyday use?

They allow for continuous work – when one battery is running low, the other is already charging, avoiding waiting in the middle of a project.
