A drill press is every woodworker’s best friend, making their jobs easier and safer with its amazing accuracy and consistent performance. Now, a drill consists of several parts, each of which has its special function in the drilling process. Every drill press comes with a chuck which is basically a clamp that tightens around your drill bit holding it firmly. It is the chuck that provides flexibility to the drill press and helps you drill perfect holes. But as with any machine, the chuck gets disfigured over time and hence need to be maintained. With time it loosens and is unable to hold the drill bit firmly and should be replaced. Discussed below is the proper process of removing and cleaning a chuck. Read through them-
Why should you remove it?
Just like any other machine, even the chuck wears out over time and needs to be replaced. An old worn out chuck cannot hold the drill bit tight and can be dangerous. Other than causing grave danger to your hands if the drill bit falls, it even affects the quality of your work.
How to remove the chuck?
The chuck found in the drill press is different from those found in a hand drill; therefore, the removal process is also different for the two. In the drill press, there is a tapered shaft fixed to the spindle called the Morse Taper to tighten the chuck. For a drill press there are two main ways to remove the chuck: The chuck key removal method and Wood piece removal method
Chuck key removal method
This is only applicable to drill press that comes with a chuck key. The steps are mentioned below;
- Pull down the handle to bring the chuck to the lowest level
- Then rotate the quill lock while holding the machine
- You’ll find a vertical slot on the shaft that can fit the chuck key
- Insert the key and tap the end to the mallet
- The chuck will easily come out of the spindle
Wood piece removal method
A wooden piece can be used for chuck removal if your drill press doesn’t have a chuck key. The steps are mentioned below:
- Place the wooden piece above the chuck. It must be pointing downwards
- Hammer it swiftly to knock the chuck out of the drill press
- Ensure that the wooden piece is long and wide enough for the purpose
Why should you clean the chuck?
Over the years the constant wear and tear of the machine reduces its productivity. The chuck may be jammed with sawdust or dirt and needs to be cleaned regularly. Refer to the following tips and steps for the proper cleaning process:
- Ensure that the chuck is disconnected from the main power supply to avoid accidents
- Remove the chuck using the steps mentioned above and open the jaws
- And then wipe it gently with a lint-free cloth to remove the dirt and dust accumulated on it
- Retract the jaws and dry it with an air-compressor to clean the leftover sawdust
- The chuck even needs lubrication for proper functioning, use grease or any other lubricant for this
- Move the jaws a couple of times for the lubricant to spread equally.
- Remember to wear safety glasses to protect your eyes from the dirt and sawdust.
How to reinstall it?
Once you have cleaned the chuck properly you need to reinstall it back to the drill press properly. The steps mentioned below would show you how:
- Raise the quill to the highest point and tighten it to the spindle
- Make sure that the drill place does interfere with the chuck installation
- Insert the chuck into the slot on the spindle and rotate it
- Close the jaws and knock the bottom with a mallet to fix it firmly.
- Try moving the chuck a bit to check the tightness and operation
- Connect it to the motor to see if its working properly
The bottom line:
The chuck must be regularly cleaned and well lubricated. And by taking proper precautions and following the above mentioned steps you would be able to remove, clean and reinstall the chuck of the drill press easily.
