How To Fix a Drill Press That Won’t Turn On (Stopped Working!)

Why is my drill press not turning on?

The reason your drill press isn’t turning on is because of a low line voltage that isn’t enough to power the drill press or your drill press isn’t properly plugged into the switch. A damaged switch that is not sending power to your drill press or irregular tuning, making your drill parts ineffective are other reasons your drill press has stopped working

Low line voltage

Power factor is very important in your drill press usage. The voltage will have to carry more current if there is a low power factor. So to transmit high current, greater conductor-size transmission lines are needed. This might be impossible with your drill press, causing it not to turn on.


Not properly plugged

Before your drill press can turn on, you must ensure it is properly plugged into the switch. This is a common mistake, even though it’s a simple fix. Whenever your drill press isn’t turning on, ensure to check if you plug it well into the switch.


A Damaged switch

The failure of your drill press switch can be attributed to mechanical concerns such as the degradation of the material or the gradual loss of the switch’s inner lubrication. However, switches can fail if the conductors in them lose their conductivity. This happens when the copper electrical contact points get covered by impurities that prevent electricity from flowing through them. This is referred to as arc suppression.


Irregular tuning

It is necessary to perform routine maintenance on a drill press to guarantee that it will continue to operate smoothly. If you don’t take care of your machine, it can stop turning on. You may maintain the unit’s smooth operation and precise drilling by doing routine checks on a few critical parts at regular intervals.


How to fix a drill press that’s not turning on

You can fix your drill press that is not turning on by repairing your switch, having regular tuning, or properly plugging your drill press.

Repairing your switch

Your switch is an important part of the drill press. And if it’s damaged, you can’t use your machine. You can fix your switch by following the steps below.

  1. Remove the machine from its connection to the power supply.
  2. Remove the cover, turn off the switch, and carefully identify each attached wire. After that, separate the wires from their respective contact tabs.
  3. Remove the switch from the plate or base it was attached to. You must pull the switch away from its plate by pressing the two attached tables inward.
  4. To open the switch’s cover, carefully pry out the plastic tabs attached to it.
  5. The two spring tabs are made of plastic hook over the outer shell. First, pull the hooks away from the shell and then open it.
  6. A rubber shroud may be included on certain switches to protect the contactor from dirt and debris. You’ll need to hoist it and take it off.
  7. Remove the inner contactor tab and any other moving parts or springs, and check them. Use alcohol to remove any buildup or black powder that resembles charcoal.
  8. Examine the contactor’s contact points, which can be elevated dots, small discs, or domes, and ensure they have been cleaned. Because they may have pits due to the arcing, you need to use some abrasive to smooth them out. It is important to not forget to clean and scour, if necessary, the stationary contact point that is located at the bottom of the shell.
  9. Put a small amount of lubricant on the pivot point so it can travel more smoothly and completely close the shell.
  10. Put everything back together in reversed order.


Properly plug your drill press.

This is a problem that is often overlooked. You might have plugged your drill press wrongly for it not to turn on. Follow these steps to ensure you don’t experience this.

  1. Check if your drills wire has fully entered the socket
  2. Ensure it is not half plugged
  3. Turn it on and start your drill press. If it starts, then your drill press wasn’t well plugged.



Tuning takes care of all the important parts of your drill press. To perform this routine, you can follow these steps.

  1. Check the power cord’s condition before removing the head cover. Then, disconnect the power cord from the electrical outlet and inspect the power cord’s condition.
  2. Ensure that the cord’s insulation does not have any breaks, and check to verify that it is securely connected to the plug at the end of the cord and the motor housing on the back of the drill press. Consider getting a new cord if there is any damage to your current one.
  3. Check the condition of the switch located on the front of the drill press while working on it. There shouldn’t be a lot of wiggle room in the switch, and it should be very simple and straightforward to turn the motor on and off. In the same way that the cord has to be changed if it is broken, so too does the switch.
  4. Unplug the electrical cord from the wall outlet before removing the head cover from the drill press’s top. Examine the belt’s condition between the two pulleys. You should get a new belt if the old one is worn out, especially if it has cracks or is fraying at the edges.
  5. After that, give the belt a small amount of rotation on the pulleys, and then check each of the pulleys, front to back, for any signs of damage or cracks. In the same way that the belt should be replaced if it becomes damaged, a pulley should also be replaced if it becomes damaged rather than continuing to utilize a defective part.


Why has my drill press stopped working?

The reason your drill press stopped working is because of the lack of lubricant on the chunk or  worn-out belts and pulleys that have come out of balance. A bad starting capacitor or blown switch are other reasons your drill press stopped working.

You should apply a small amount of drying lubricant inside the chuck. This will ensure that the chuck’s jaws continue to operate smoothly, which is crucial for accurate bit centering. Rotate the chuck’s shell until the jaws are completely open. Next, use a blast of compressed air to clean the interior of the chuck (wear goggles to keep flying dust out of your eyes).

Put some lubrication on the inside by spraying it, and then move the jaws back and forth several times while the extra lube drips out. Use a clean rag to remove any residue that may have been left. Also, regular maintenance will surely make you stay away from a faulty drill press.


Why is my drill press not spinning?

Your drill press isn’t spinning because the drill bit is not properly centered in the chuck of the drill, or your chunk isn’t tightened properly. Another reason your drill press isn’t spinning is inadequate tension on the drill bit.

It only takes a drill bit that is slightly off-center to render a drill useless, and it’s incredibly easy to clamp the drill bit in the wrong position by accident. Twist the chuck, so the available hole is no longer large enough to accommodate the drill bit. This will ensure that the bit is properly centered in the chuck.

The next step is gradually enlarging the hole until it is big enough to accommodate the bit you are using. Put the bit in the hole until it is completely submerged. Make sure the bit is secure before you tighten it. Because the hole being drilled is never big enough to allow the drill bit to move around and become orientated wrongly, this method compels the drill bit to be perfectly aligned.

Note: The drill chuck or the user’s inexperience are the most common causes of an inactive drill press. Contact the manufacturer of your drill if you have already tried replacing the chuck but are still having problems. They could provide you with solutions specific to the model of the drill you have, or they might offer you an offer to replace the drill.


Why is my Delta drill press not working?

The reason your Delta drill press isn’t working is because of a bad starting capacitor, therefore, making your drill inactive and noisy or a damaged chunk. A worn-out belt is another reason your Delta drill press isn’t working.

Bad starting capacitor

If your drill press suddenly stops working, this could indicate a faulty capacitor. Here are steps to follow to fix your bad capacitor.

  1. Using an accurate electrical meter, you can determine whether or not your capacitor is working properly.
  2. The microfarad is the unit of measure for capacitance. A capacitor’s recommended microfarad value, abbreviated as either mfd or uf, is printed on the component’s label.
  3. If the microfarad value displayed on your electrical meter is either excessively high or excessively low, your capacitor is malfunctioning.
  4. Make sure that you use a screwdriver with an insulated handle to create a short between the terminals of your capacitor before you test it. This will assist you in dissipating any accumulated power.
  5. For the capacitor to be of any use, its value must fall within the range specified on the label.
  6. It is important to remember that capacitors do not have any polarity, so it does not matter which side the wires go on.
  7. If you have more than two wires running to the capacitor, the wires connected on one side must always be paired together on the other side of the capacitor.


A Damaged chunk

A drill chuck is an adjustable clamp with a slot in which drill bits can be stored and secured. These are standard features on all drills designed to allow the operator to select the appropriate bit for the task at hand when working on various projects.


  1. Position the chuck removal tool, so it fits into the spindle window of the press.
  2. Use a light hammering motion to move the tool used to remove the chuck further into the window until the chuck is released from the press.
  3. To begin, obtain a hammer and a sturdy and functionally sized piece of hardwood.
  4. Place the piece of hardwood at an angle directly above the chuck.
  5. Using the hammer, give the hardwood a few solid blows to the head, and the chuck should come out without further effort. If you want to avoid the risk of bending the chuck shaft or the drill spindle, just make sure that the energy of the hammer impact is directed as far downward as feasible.
  6. Using a rag and some sort of degreasing agent, thoroughly clean the spindle of the chuck. Because it evaporates so quickly, acetone is particularly useful in this context. Additionally, make use of a rag and some acetone to clean the interior of the drill press’s spindle.
  7. Once the spindle and shaft have been cleaned, insert the drill chuck into the press so that it is secure enough to remain in place for a few seconds on its own.
  8. To protect the jaws of the drill press chuck from being damaged, retract them into their housing.
  9. Reduce the height of the press table to create more room for swinging the hammer.
  10. With a wooden or rubber mallet, strike the bottom of the chuck two or three times rapidly and strongly.


A worn out belt

A worn belt, bent or out-of-balance pulleys, or any combination of the three can be why your Delta press drill isn’t working. Check these steps to repair or replace your belt.

  1. Unplug the drill press, take off the head cover of the machine, and rotate the belt manually while performing a visual inspection to determine whether or not the belt needs to be replaced.
  2. You should replace it as soon as possible if it has fractures, ply separations, or lumpy areas.
  3. If the belt functions normally, you should verify its correct tension.
  4. By applying pressure in the middle, between the pulleys, you should be able to slightly bend it (approximately a quarter of an inch to three-eighths of an inch).
  5. Adjust the tension according to the instructions provided in the machine’s manual if the belt is too loose or too tight.


Why is my Ryobi drill press not working?

The reason your Ryobi drill press isn’t working is because of a blocked trigger mechanism or a dead battery making your Ryobi drill press inactive. Another reason your Ryobi drill press isn’t working is an electrical problem with the motor’s wiring.

Dead Battery

Check that the drill’s battery is fully charged and placed into the tool. Check that the battery contacts and the ones in the drill are clean.

  1. Press both push tabs on the battery simultaneously
  2. They can be found in the middle of both sides of the battery and directly below the green housing on both of those sides.
  3. Check if the battery is fully charged before putting it back.


Blocked Trigger Mechanism

The trigger assembly is what controls the amount of power that is supplied to the motor as well as the direction in which the motor rotates. Below are steps to follow to unblock your trigger.

  1. Check to see that nothing is blocking the trigger from being fully depressed and making contact with the switch assembly, such as sawdust or debris. If there is, remove it.
  2. To clean this, remove the housing and use a dry cloth or compressed air to remove any debris that may have become lodged inside.


Faulty Motor Wiring

If the trigger appears to be operating well, you should examine the wiring to ensure that it is in sound condition and extends from the switch assembly to the motor. If the wiring is not in good condition, as indicated by broken contacts or exposed bare wire, the wires should be replaced and soldered. Check to see that the new wiring follows the path taken by the old wiring. Use the following steps to repair your faulty wire.

  1. While holding onto both tabs, remove the battery from inside the drill housing.
  2. To remove the eight screws measuring 16 millimeters securing the housing, you will need a Phillips #2 screwdriver.
  3. To remove the four screws measuring 25.4 mm, you will need a T20 Torx screwdriver. These screws secure the front of the housing.
  4. The data label should be facing up when the housing is opened.
  5. Remove the motor and chuck assembly from its housing by lifting it.
  6. Take out the sleeve bearing assembly and gear case from the inner case assembly.
  7. Take the motor assembly and the camshaft off of the car.
  8. Take out the metal pins that are on each side of the assembly of the inner casing.
  9. It is easiest to start pushing the pin through the opening from one side, and once enough of the pin is through, grab it with the tweezers and pull it the rest of the way through.
  10. When putting everything back together, check that the pin enters the hole in a straight line and exits on the other side rather than entering the hole at an angle and entering the inner case assembly.
  11. Take the ring gear from the wheel.
  12. Wedge the spudger under one side of the inner case assembly to help raise the ring gear out of the assembly, then switch to the other side and repeat the process until the gear ring is removed. This will help lift the ring gear.
  13. Take off the two 8-millimeter screws and the spring washers connecting the inner case assembly to the motor.
  14. Split it into two pieces.
  15. Remove the black and red wires from the solder joint that connects the motor to the trigger assembly using a soldering iron.
  16. Make the connection between the new motor and the trigger assembly with the soldering iron. s
  17. Check that the red wire is connected to the lead with a red mark.
