Bosch GSR 120-LI Professional Pros/Cons and My Thought

The Bosch GSR 120-LI Professional is a 12-volt cordless drill that is part of Bosch's Professional range. It features a 2-speed gearbox, hammer action, and comes with two 1.5Ah batteries, a charger, and a carrying case.

Pros:

  • Powerful: The Bosch GSR 120-LI Professional has a maximum torque of 30 Nm, which makes it powerful enough to drill through wood, metal, and concrete.
  • Versatile: The hammer action allows the drill to be used for masonry work, and the 2-speed gearbox gives users more control over the drilling speed.
  • Lightweight: The Bosch GSR 120-LI Professional weighs just 1.5 kg, making it easy to use for extended periods of time.
  • Durable: The drill is made from high-quality materials and is designed to withstand heavy use.
  • Long battery life: The two 1.5Ah batteries provide up to 80 minutes of runtime, so you can get a lot of work done before needing to recharge.

Cons:

  • Pricey: The Bosch GSR 120-LI Professional is more expensive than some other 12-volt cordless drills on the market.
  • No LED light: The drill does not have an LED light, which can make it difficult to see what you are drilling in low-light conditions.
  • No belt clip: The drill does not come with a belt clip, so you have to carry it by hand or in the carrying case.

User reviews:

Overall, the Bosch GSR 120-LI Professional has received positive reviews from users. Many users praised the drill's power, versatility, and lightweight design. Some users also mentioned that the drill was easy to use and had a long battery life.

Bosch GSR 120-LI Professional Problems and Solutions

Sure. Here are some common issues and problems with the Bosch GSR 120-LI Professional drill and their solutions:

  • The drill makes a loud noise and/or smokes. This is usually caused by a problem with the motor. If the drill is still under warranty, you can contact Bosch for a replacement motor. If the drill is no longer under warranty, you can try to repair the motor yourself. There are a few tutorials available online that show you how to do this.
  • The drill won't turn on. This could be caused by a dead battery, a loose connection, or a problem with the switch. Check the battery first to make sure it is charged. If the battery is charged, check the connections to make sure they are tight. If the connections are tight, the problem may be with the switch. You can try to clean the switch or replace it if necessary.
  • The drill doesn't drill straight. This could be caused by a bent chuck or a dull bit. Check the chuck to make sure it is not bent. If the chuck is not bent, the bit may be dull. You can try sharpening the bit or replacing it.
  • The drill vibrates too much. This could be caused by a loose motor mount or a worn-out bearing. Check the motor mount to make sure it is tight. If the motor mount is tight, the problem may be with a bearing. You can try to replace the bearing yourself or take the drill to a repair shop.

Here are some additional tips for troubleshooting common Bosch GSR 120-LI Professional drill problems:

  • Check the user manual. The user manual may have troubleshooting tips for specific problems.
  • Clean the drill. Dust and debris can build up inside the drill and cause problems. Use a brush or compressed air to clean the drill regularly.
  • Lubricate the drill. The drill's moving parts need to be lubricated to prevent wear and tear. Use a light oil or grease to lubricate the drill every few months.
  • Store the drill properly. When you are not using the drill, store it in a cool, dry place. Avoid storing the drill in direct sunlight or in extreme temperatures.

I hope this helps!
