  • The magnetic base is a really helpful feature, especially if you need to drill in metal. It keeps the drill stable and prevents it from slipping, which can be especially important when drilling in thin metal.
  • The two-speed gearbox is a nice touch. It allows you to choose the right speed for the job, which can help you to drill more accurately and efficiently.

  • The drill is a bit heavy, but it is still manageable for most people. If you need a more portable drill, there are other options available.
  • The drill is also a bit noisy, but it is not as loud as some other drills on the market.
  • The drill is expensive, but it is a quality tool that should last for many years. If you are looking for a powerful and reliable drill for professional use, the Bosch GBM 50-2 Professional is a great option.
