A cordless drill can be converted to a corded drill. To do that, first, replace the battery with a DC power supply or a transformer and a 4-diode rectifier. Then, attach the old terminal and connect the wires from the drill to the output and the main current lines wires to the input. Finally, supply power from a wall socket to the power supply/transformer and enjoy the corded drill.
- It’s possible to convert a cordless drill to a corded one using both transformers and power supplies.
- Converting to a corded drill will provide extra torque and a continuous power supply.
- Incorrect installation may lead to motor overheating, noise and vibration, and torque loss.
Is It Possible to Convert a Cordless Drill to Corded?
Yes, it’s possible to convert a cordless drill to a corded one. All components on the cordless drill can be shifted to a corded drill and the drill can have a continuous power source.
The in-depth guideline for converting a cordless drill to a corded drill has been discussed in the next segment.
How to Convert a Cordless Drill to Corded?
To convert a cordless drill to a corded drill, you need to gather some items beforehand. The required items are:
- DC power supply (choose a power supply small enough to fit inside the battery compartment)
- Glue gun
- Heat shrink tubes
- Soldering iron
- Transformer (240-250 AC)
- 4 diode rectifier
|DC power supply||Safe & reliable to useAuto power calculation feature|
|Screwdriver set||Added grip texture for improved handlingQuick rotation control|
|Hot glue gun||Material made from high-tech electronic ceramicDetachable copper nozzle|
|Soldering iron||Digital display and power switchExtra accessories|
|4 diode rectifier||4 copper diodes|
|Digital Multimeter||Low power reminder and overload protectionFast and accurate|
|Transformer||OEM reversing valves and coilWarranty Available|
|Heat shrink tubes||Premium materialEasy to use and store|
Now that you’ve gathered the necessary tools, let’s get to the steps. Here are the steps to convert a cordless drill to a corded one:
Step 1: Start off by taking out the batteries of the cordless drill. Using screwdrivers, unscrew the bottom plate of the battery compartment and take the battery out.
Step 2: Then, strip out the terminals from the old battery compartment. You can use a bolt cutter for this. Adjust the bolt cutter and pry out the terminal. Mark the positive and negative sides of the terminal using a marker.
Step 3: After that, attach 2 wires on both ends of the terminal using a soldering iron. After soldering the wires, make sure you seal the connection by using heat shrink tubes.
Step 4: After that, use a glue gun to attach the terminal to the battery compartment. Use a small amount of the glue to not disrupt the current flow.
Step 5: Next, attach the 2 wires to the DC power supply to measure the current. Attach the 2 wires with the AC input and attach the live wires to the DC output.
Step 6: Attach the live and neutral wires of the DC power supply to a wall socket and turn it on. Refrain from using an impact wrench while doing so.
Step 7: Using a multimeter, you can measure the output voltage. Check both the output and input side. Make sure that the voltage is around the same as the old battery inside the cordless drill.
Step 8: If you’re happy with the torque of the drill, you can fit the DC power supply inside the battery compartment and enjoy the corded drill. However, if you need more current/torque, follow the next step.
Step 9: Take a transformer and 4-diode rectifier. After that, connect the main electricity (AC) line with the transformer, and connect the transformer’s output with 2 pins of the diode.
Step 10: Then, connect the 2 outgoing wires from the drill to the remaining diodes. This way, the input current is transformed and the rectifier will turn the current to DC. Finally, the DC current with high amperage will be fed to the drill.
Note that, if you use a DC power supply that’s small enough, the corded drill will be somewhat portable. However, using a transformer and rectifier will require you to carry them separately when using the drill. It all depends on your preferences!
Common Issues & Troubleshooting of Converting a Cordless Drill to Corded
Now let’s go through some common issues and troubleshooting you may have to perform after the conversion.
When converting a cordless drill, many people choose a DC power supply that can supply the volt, but not the amperage.
The drill might lose torque whilst converting if the power supply amperage is too low. Low amperage can create a lot of problems in mechanical power tools. For instance, when a wood planer doesn’t pull through wood, it probably has a low amperage.
To troubleshoot this issue, use a power supply that can provide 5 amperes or more. That way, the drill can retain the torque.
If the output amperage gets too high or out of control, the drill motor will start overheating. To prevent this from happening, make sure you’re using authentic transformers and power supplies.
As a security measure, you can fit an amperage meter on the drill to monitor the incoming and outgoing amperage. This way, you can minimize the risks of damaging the drill and yourself.
Noise and Vibration:
Worn-out parts of the drill can be the main reason for this issue. Any chipped/broken parts of gears inside the drill with missing teeth can create extra noise and vibration.
To ensure that, take the drill apart again and look for broken parts. If there are any damaged parts, replace them.
Furthermore, make sure you’re reassembling the drill correctly. Since the conversion requires you to take the drill apart, there might be a good chance that it’s reassembled incorrectly.
This doesn’t apply to the differences between cordless and corded drills, it’s necessary for both. However, cordless drills suffer less from damaged components since the output torque is lower than a corded drill.
That’s everything you need to know when asking, “Can you convert a cordless drill to a corded one?”
If the conversion seems too technical for you, don’t stress! You can convert your cordless drills into corded drills at electric shops. That way, you can save time and effort in exchange for mechanical supervision and a small labor cost. Have a great day.
