No matter how long I charge it, the drill doesn't stay working
If your drill operates while connected to charger, but does not operate while disconnected, you may have a defective battery. If this is the case, you may need to purchase a new battery and install it using our battery replacement guide.
At this point you have determined that the battery is indeed not defective. Now, check and see drill operates while connected to charger. If the drill still does not turn on while connected to a power outlet then check and see if the AC cord has any kinks or exposed wire. If this is the case, you will need to buy a new AC cord.
The drill gets to a certain point and bogs down
Disassemble the drill and locate the motor. While drill is disassembled, squeeze the trigger and see if the motor is rotating properly. If motor is not functioning correctly, visit our motor replacement page to learn how to properly replace your drill's motor.
The drill switch is not adjustable
Make sure that the speed switch on your drill is positioned in the proper position. Locate the gear indicator on the top of the drill. Make sure the switch is set on the high-torque setting. This setting allows the drill to deliver 130-inch-pounds of power. If your project requires more torque, you may want to consider getting a more powerful drill. Visit our speed switch replacement page to learn how to properly replace the switch.
The bit will not stay steady while in operation
