Inside the cordless drill

Today I want to talk about parts from which cordless drill is assembled. Take a look at the parts diagram of cordless drill DeWALT DC727:





Main parts of cordless drill are:
  • 1 - CLAMSHELL SET

  • 2 - CHUCK

  • 9 - DC SWITCH

  • 11 - ADJUST COLLAR

  • 13 - MOTOR

  • 14 - TRANSMISSION/CLUTCH ASSEMBLY

  • 866 - BATTERY




You can see that cordless drill is very simple tool. And now you can ask, so if cordless drills are so simple inside, why exist so much different models on the market?
And the answer is: the main difference between models consist in battery type and battery voltage, motor type, supported operations and weight. Exist and other parameters but this is key factors.


In conclusion these are the main features to remember to look for when buying a cordless drill:

  • Battery type and Voltage
