How to choose a corded drill?

Each type of corded drill has unique properties.

  • Power. Determine the resistance of the drill bit. Its measurement is expressed in watts (W). As a general rule, drills with 750 W or less are suitable for DIY or private work. Those over 750 W are perfect for professional use or more demanding jobs.
  • Speed ​​control. Cable types can have one or two speeds. You can adjust the drill rotation speed, accuracy and capacity.
    • Electronic speed control. It allows us to adapt the speed of rotation by means of the trigger, with great precision.
    • Mechanical speed control, with one or two speeds. At low speeds, the tool has more strength, but the drill spins more slowly and is therefore used to work on hard materials such as metal. On the other hand, high speeds are recommended for use on all other materials.
  • Percussion. Machines that incorporate a percussion function perform a rotation movement of the drill and hammering. You can use hammer or non-hammer mode, depending on the material.
    • Without percussion: It is used in bolting or drilling work on all types of materials. Brick and concrete would be the exception.

    • Lithium battery (li): The most recommended due to the tool’s durability. They have no memory effect, so the battery does not lose capacity if it is charged before being discharged. The battery does not need to be fully discharged to recharge it.
    • Nickel-cadmium (Ni-Cd) batteries: They are cheaper, but start to disappear due to the disadvantages compared to lithium batteries.

Each battery has particular characteristics:

  • Voltage. The voltage is expressed in volts (V). The higher the battery voltage, the greater the working capacity.
  • Amperage: The amperes (A) are the capacity of the battery, the higher the amperage, the longer it works without having to recharge it.
  • charging time: Lithium batteries take much less time to charge than nickel-cadmium batteries. If you are one of those who will use the drill a lot, look for models that allow fast charges, otherwise, you will need a replacement battery to avoid major downtime while working.
  • Weight. Determining feature for easy tool handling. Lithium batteries are more manageable, compact and lighter.
  • Durability. Lithium batteries have twice as many nickel batteries. Lithium batteries discharge more slowly than others.
