Appears to be a brushed DC motor, which is OK. ~1.25A, but more on start-up.
Dimensions would be nice, and I would like to have a spec sheet, but seems to be good for a small engraver if the ‘run-out’ is not too great.
Drill chuck suggests run-out is not high on the designers mind, but may be OK for a simple, and small, CNC router.
I agree with previous comment, a collet would be better, but perhaps that writer is looking for a pulley to a precision spindle.
Not that it’s that important to get the chuck off, unless it turns out to be out of axis, or loose, but often you need to open the chuck as wide as possible with the chuck key, and see if there is a screw deep down inside the chuck screwed into the shaft. I’d expect there might be one.
I was thinking of one for drilling home made PCBs in a 3D printed drill press. Or using one in an "Eggbot" style CNC set up for engraving rings (copper/brass -probably not silver or gold!)
