The specs for Bosch 3360 drill, which is where I'm guessing this motor comes from, on the boschtools.com web site lists the drill as having a stall torque of 400 lb-in (45.3 N·m) and a no-load speed of 450 rpm in low gear. Doing a little math that gives it a stall current 185A at 12V and a peak power output of 527 watts. In high gear you'd get stall torque of 12.7 N·m and a no-load speed of 1598 rpm and with no gear box you'd get stall torque of 1.06 N·m and a no-load speed of 19170 rpm.
