If your drill has a brushed motor, it's totally normal to get some sparks. These sparks should be consistent and relatively contained inside the drill. However, if there are intermittent and violent sparks around the motor, power cord, or battery compartment, this is a sign of an issue that must be repaired.
Also, Cordless drills will spark normally within the drill itself as the carbon brushes pass by the commutator. These small sparks are a normal part of the cordless drill operation.
If you have a brushless unit, you'd need to get in contact with our support team at 888-331-4569 or email them at support.us@support-craftsman.zendesk.com

This is a helpful clarification! Many users get concerned seeing sparks, but understanding that consistent internal sparking in brushed motors is normal really eases worries. It’s good to know when it becomes a sign of a problem.
This is exactly the clarification I needed, thanks! I had a cheap old corded drill that started throwing sparks that looked like fireworks, not just the usual little blue ones, and I retired it instantly. Turns out, it was probably those intermittent, violent sparks you mention—I should have checked the brushes first! Honestly, dealing with the tools and getting covered in dust always makes me ready for a quick mental break. If anyone else is looking for a serious dose of nostalgia distraction after a frustrating DIY session, you should check out the old version of that classic racer; you can download now. Appreciate the great diagnostic info!
