Why did my drill stop working

When a drill suddenly stops, the question on your lips is 'why did my drill stop working?' There are several plausible culprits, but most start with power delivery and basic safety. According to Drill Bits Pro, battery health and overload protection are among the most common reasons drills halt. In practice, cordless drills often fail to run because the battery is dead, not seated correctly, or because the charger has failed to recharge it. Corded drills can fail due to a blown fuse, an unplugged outlet, or a damaged cord. Less obvious but important are mechanical issues inside the chuck and gearbox, which can prevent the motor from delivering torque even if electricity is reaching the windings. Before you dive into disassembly, keep in mind that quick checks can save time and prevent damage. The goal is to identify whether this is a simple power issue you can fix in minutes, or a deeper fault that needs a professional repair.

According to Drill Bits Pro, addressing the most common power and connection problems first will often restore function without tools. If you can determine it’s a power issue, you’ll save time and avoid unnecessary repairs.
