Why does my drill stop spinning? - Fix It Cape Town

Drills are an essential tool in any handyman’s or DIY enthusiast’s arsenal. They are widely used for various projects, ranging from home renovations to professional construction work. However, imagine the frustration of having a drill suddenly stop spinning in the middle of a task. This unexpected halt can be caused by several reasons, ranging from power issues to mechanical problems. In this article, we will delve into the potential reasons behind such occurrences and discuss ways to remedy them.

Power Issues

1. Battery Depletion

  • If you are using a cordless drill, it is crucial to check the battery level.
  • Low battery power can cause the drill to lose speed or cease spinning altogether.
  • Safeguard against this issue by keeping spare batteries fully charged for uninterrupted usage.

2. Loose Connections

  • Faulty connections often lead to power interruptions in corded drills.
  • Make sure the power plug is securely inserted into the electrical outlet and the drill’s power cord.
  • If the drill has a detachable cord, check for loose connections, and ensure it is firmly attached.

3. Circuit Overload

  • Using multiple power tools simultaneously on the same circuit can lead to electrical overload.
  • If your drill keeps stopping, it could be due to the circuit being overwhelmed.
  • Distribute the power load evenly across different circuits or consider using a dedicated circuit for power tools.

Mechanical Problems

1. Worn Brushes

  • The brushes in an electric drill facilitate electrical contact between the armature and the motor.
  • Over time, these brushes can wear down, resulting in a loss of power and eventual halt.
  • Inspect and replace the brushes regularly to maintain optimal performance.

2. Overheating

  • Continuous use without proper cooling can cause the drill’s internal components to overheat.
  • Many drills have built-in thermal protectors that automatically shut down the tool to prevent damage.
  • Allow the drill to cool down completely before resuming work to avoid recurrent overheating issues.

3. Jammed Chuck or Bit

  • A jammed chuck or a bit stuck in the material can prevent the drill from spinning.
  • Ensure the chuck is properly tightened around the bit.
  • If a bit becomes lodged, turn off the drill, and gently and safely remove the obstruction before continuing.

4. Gear Slippage

  • A drill uses gears to transfer power from the motor to the chuck.
  • Over time, these gears may wear out or become misaligned, resulting in slippage.
  • If you observe unusual sounds or jerky movements, it may indicate a problem with the gears requiring Repair or replacement.

Frequently Asked Questions (FAQs)

  1. Can a drill stop spinning due to operator error?
  2. Yes, operator error can be a potential cause for a drill stopping during use.
  3. Incorrect usage techniques or applying excessive force can strain the drill’s motor, leading to it shutting down.
  4. Ensure you are using the drill correctly and not exerting unnecessary pressure.

  5. What should I do if my drill continually stops spinning?

  6. Start by identifying the possible causes mentioned earlier in this article.
  7. Carefully inspect the drill for signs of damage or worn-out parts.
  8. If the issue persists, consult a professional for diagnosis and repair.

  9. Why does my drill stop spinning intermittently?

  10. Intermittent stopping can occur due to loose connections, overheating, or worn brushes.
  11. Check for loose plugs, allow the drill to cool down, and inspect the brushes for wear.

  12. Can a drill stop spinning if the material is too hard?

  13. Drills are designed to handle a range of materials, but certain materials might put excessive strain on the drill’s motor.
  14. If you encounter difficulties while drilling into a hard material, try using a more powerful drill or using specialized bits designed for tough materials.


Understanding the potential reasons behind a drill stopping during use can help troubleshoot and rectify the issue promptly. Power issues, such as battery depletion or loose connections, can lead to unexpected halts. On the other hand, mechanical problems like worn brushes, overheating, jammed chucks, gear slippage, or exceeding the drill’s capabilities when drilling tough materials can also cause interruptions. By being aware of these factors, you can take appropriate measures to rectify the problem and ensure smooth operation of your drill. Remember to prioritize safety and consult a professional if the issue persists or requires complex repairs.
