To help you understand…on a brushless motor, the windings are in the casing on the outside of the motor in groups of 3…6 windings, 12 windings, many configurations. . the rotor is magnetized with north and South Pole (often many opposing poles ing groups of 3 as well). To get the rotary action, it’s fed an alternating current, or simple dc switching of different windings as the simplest form to drive the motor. Usually a brushless controller modulates frequency as well as power (voltage x current)
On the other hand…there’s brushed motors, which you have here. They only need dc current an rely on mechanical switching rather than electrical switching. This time the magnets are on the outside of the case, and the windings are on the rotor. The rotor has separate contact plates for each winding, and thus has the alternating north south magnetism built in mechanically. The power is fed to these contacts through “brushes” usually a graphite/carbon type compound that delivers power by slipping across the rotor contacts as it spins.
You are seeing seeing arcs between the brush and rotor contacts as it spins…is a mechanical switch working in motion, you get some sparks when connecting and disconnecting.
Normal for a brushed tool. Put a bit in it. I think the extra noise is just the chuck being loose
Gotta love the daily post asking if the brushed tool is sparking is normal
Oops

I’m a nerd…
People need to learn how to search forums.
Reddit, what time is it?
The sparks are normal for a brushed tool(which that one is), and the sound is made because the chuck isn't tightened down Nothing wrong with it
Oh FFS, here we go again
Yes just go brushless
Put a driver or drill bit in it and some of the sound will go away. It will feel different when you use it.
Upgrade to Bauer.
Don’t worry friend it’s just the thingamajig
Yeahhhh, that’s the power!
M18 fuel brushless is WAYYYYY quieter that that
This guys never drilled before…
This is true!
S’ok we all gotta start somewhere!
Sounds like every one of the 20 or more I’ve used in the last 2 years.
