  • Power Supply

    Battery

    Indicates whether the tool operates on battery or directly from the mains. Battery-powered tools offer freedom of movement, while electric ones provide continuous power.

  • Number of Batteries

    0

    Solo - The package does not include a battery and charger. Please prefer it if you already have a compatible battery from other tools.

  • Speed Setting

    Ability to adjust the rotation speed according to the task (low speed for screwing, higher speed for drilling into larger walls, maximum speed for drilling into concrete)

  • Voltage

    It corresponds to the power of the tool. Higher voltage means more power and durability for heavy-duty tasks.

  • Maximum Motor Speed

    The maximum rotational speed of the engine in revolutions per minute. For drilling tasks, a number of revolutions up to 1500rpm is perfectly satisfactory, as there is a risk of breaking the drill bit due to the increase in temperature above that level, while for screwing tasks higher speeds can be used, especially if the material is soft such as wood or plasterboard.

  • Chuck Diameter

    The maximum size of drill bit or tip you can use. The larger the chuck, the more accessories it fits.

  • Torque Setting

    The ability to adjust the torque of the tool's operation according to the task at hand. (Low torque for easy screwing/unscrewing, high torque for drilling into walls).

  • Brushless

    The advantage that brushless motors have over brushed ones is that they do not have friction since there are no carbon brushes. Without carbon brushes, the motors are more efficient and have a longer lifespan as there is no wear (the carbon brushes in brushed motors wear out with use). They produce less noise, maintain constant torque at all speeds, do not overheat, and require no maintenance.

    It features a brushless motor that produces less heat and friction, resulting in less wear on the motor and a longer battery life. It also provides more stable power and speed, allowing for smoother and more precise operation. 2. In general, brushless motors are more efficient and have a longer lifespan than motors with brushes, making them a popular choice for electric tools.

Description

Description

Discover ultimate flexibility in tight spaces with the compact PRO GSR12V-31 drill driver and its advanced brushless motor.

At a glance

  • 144 mm head length: 18% shorter design than its predecessor for easy access to extremely tight spaces.
  • Brushless motor: Powerful brushless motor and new gearbox for consistent, high performance.
  • Increased torque of 18 Nm: 30% higher soft torque for effective screw driving and demanding tasks.
  • Battery indicator: Built-in light indicator for continuously monitoring the remaining runtime.

Extra-compact design for hard-to-reach places

When working in tight spaces, every millimeter counts. With a head length of just 144 mm — 18% shorter than the previous model — this tool reaches everywhere. The brushless motor and new gearbox deliver exceptional power, while the soft-grip handle and weight of just 0.8 kg help reduce hand fatigue, even during demanding overhead tasks.

High power and material versatility

Tackle any challenge in wood, metal, or plastic with absolute precision. The increased soft torque of 18 Nm, combined with a maximum torque of 50 Nm and 20 torque settings, gives you complete control. Plus, the 10 mm keyless chuck and 2-speed mechanism (up to 1,700 rpm) ensure fast and efficient drilling in any material.

Smart control and comfortable operation

Plan your daily work without unexpected interruptions. The built-in battery level indicator keeps you informed of the remaining charge, while the powerful LED light clearly illuminates dark surfaces. Thanks to compatibility with Bosch 12V Li-Ion batteries, you can enjoy reliable runtime and smooth operation at all times.
