Common Power Drill Parts Failures and How to Fix Them

Power drills have several parts, all of which are important in the proper functioning of the tool. These are a few of the most common mistakes and how to fix them before they get out of hand.

1. Motor Failure

• The drill does not start or starts and runs at a very low speed.

• Abnormal vibrations or heat emanating from the motor.

• The motor seems to be emitting a burning smell.

• 
  

How to Fix:

• Check the Power Source: Make sure that the battery is charged to the optimum level or the cord (in the case of corded models) is connected properly.

• Clean the Motor: The motor may get dusty or have debris that may lead to overheating. To extend its lifespan, the motor needs to be cleaned and maintained on a regular basis.

• Replace the Motor: If the motor is burnt out or severely damaged, it is necessary to replace it with a new one.

2. Chuck Issues

• The chuck won’t tighten properly.

• Drill bits become loose or cannot be fixed properly.

• The chuck is either jammed or difficult to turn.

  
  

How to Fix:

1. Clean the Chuck: It is easily clogged by dirt and debris which may lead to its malfunctioning. Make sure the chuck is greased and clean.

2. Tighten the Chuck: Make sure the chuck is tightened well, especially if it is a keyless chuck. If it’s still slipping, then perhaps it is high time to replace the chuck.

3. Battery Problems (Cordless Drills)

• The drill will not charge properly.

• The battery discharges very fast even when fully charged.

• The battery is swollen or leaking.

  
  

How to Fix:

1. Clean Battery Contacts:  Dust or any kind of oxidation might hamper with electrical connection. Clean the contacts to ensure good connection.

2. Replace the Battery: It's time to replace the battery if it's damaged or dead.

4. Trigger Malfunctions

• The trigger is unresponsive 

• The speed control is not functioning properly.

• The trigger is jammed, and the drill keeps running.

  
  

How to Fix:

1. Check for Obstructions: Debris and dirt might obstruct the trigger mechanism. Remove any obstructions.

2. Test the Trigger: If there is no response, test the trigger switch with another drill or replace the faulty switch.

5. Gearbox Issues

• It grinds or slips during the drilling process.

• Difficulty switching between speed settings.

• The drill is less powerful or has less torque, especially when used for heavy drilling.

  
  

How to Fix:

1. Lubricate the Gearbox: Gears are prone to wear out due to the absence of lubrication. Use an appropriate lubricant to ensure that the gears do not jam.

2. Replace Worn Gears: Over time, the gears of the gearbox might get damaged and won’t shift as they should or make loud noises, so the gears need to be replaced.

6. Clutch Failure

• The drill is still screwed too deep or not deep enough.

• Difficulty adjusting the torque settings.

  
  

How to Fix:

1. Adjust Clutch Settings:  Ensure that the clutch settings are appropriate for the job that is to be done. Modify them as required for better control of torque.

2. Check for Wear: If the shifting is not smooth and the clutch cleans out the gears automatically, then the clutch may have worn out and a new one needs to be installed.

In this article, we have pointed out some of the most frequent power drill part failures and how you can address them. That is why it is important to recognize the signs early enough and correct the faults before they get out of hand. Stay informed and your drill will remain reliable for all your future projects and ensure that you are always satisfied.
