There is a marked difference between the drive shaft seizing against the motor, and the sound of the clutch engaging. One is a whine, the other a chattering. I also use drills everyday, cordless as well as corded, impact, screwguns, hammer drills, just about any rotary device you can use to insert something into something else with. That was a clutch engaging. There is no doubt in my mind of that.
