I am going to show you how to modify this
to the BEST cordless screwdriver
originally it is a industrial use for assembling DC 36V
torque adjustable from 0.2kg to 17kg screwdriver
the rotating speed is 750rpm at 24v
the max speed is 1200rpm at 36v
it is too fast for home use
I will modify it to a 8.4v lithium battery power cordless screwdriver
the rotating speed is down to 230rpm at 8.4v
it is suitable for home electrical appliances and electronic product assembling or disassembling
