Chuck is Wobbling ¶ 

When operating the drill, the chuck is wobbling.

The Chuck is Loose ¶ 

The chuck is a specialized clamp that holds the drill bit in place to ensure smooth drilling. It is the spinning black piece located directly behind where the drill bit is inserted. The chuck will wobble if it is not fully tightened. To fix this, rotate the chuck clockwise until the wobbling stops.

Build up could be blocking the chuck from being able to fully tighten. Remove the chuck and clean any build up. You may need to replace the chuck.

The Clutch is Broken ¶ 

The clutch of the drill is located directly above the reverse switch and allows you to control the amount of torque being applied to a screw so it doesn’t go in too deep. So if your drill gears are making a loud noise or any noise that does not sound normal when it is rotating it may help to take the clutch off and see if it is broken. To replace the clutch, check out our replacement guide.

Drill is Stuck in Reverse ¶ 

The drill will only drill in the reverse direction.

The Directional Switch is Engaged in the Reverse Position ¶ 

There is a switch located just above the trigger that makes the drill switch directions when pressed. Switch it to the opposite position and see if this causes the drill to go forwards again,
