5. Check Depth: Regularly check the depth of the hole and adjust the drill's speed and pressure accordingly to achieve precise results.

6. Release the Trigger: Once the desired depth is reached, release the trigger and allow the drill to come to a complete stop before removing it from the hole.

Safety Precautions When Using a Bosch Hammer Drill

Safety should always be paramount when operating a Bosch hammer drill. Observe these precautions to minimize risks:

• Wear Protective Gear: Always wear safety glasses, earplugs, and a dust mask when drilling to protect yourself from flying debris, noise, and dust inhalation.

• Secure the Workpiece: Clamp or secure the workpiece firmly to prevent it from moving during drilling.

• Inspect the Drill: Before each use, inspect the drill for any damage or loose components and ensure all safety features are functioning properly.

• Avoid Overheating: Allow the drill to cool down periodically to prevent overheating and damage to the motor.

• Handle with Care: Store the drill in a dry and secure location and avoid dropping or mishandling it.

Bosch Hammer Drill Maintenance and Care

Regular maintenance and care are essential to extend the lifespan and performance of your Bosch hammer drill. Follow these tips to keep your drill in optimal condition:
