Are the torque settings in pouns per square inch
Asked by 480 January 29, 20175
AnswersPounds per square inch is a pressue measurement, not a torque measurement. Torque is measured in inch or foot pounds. This tool is not a torque wrench so the answer to your question is NO.

Great driver,Tons of tork for 4 volts, the battery lasts a long time, I have been using it off and on for a month and I'm just now down to three lights on the indicator,the clutch ratchets in reverse which is good and cuts the motor off forward. I expect to be using this for a long time to come.

The heaviest duty 4 volt screwdriver we have used, up to the task of industrial assembly
We wanted a battery operated screwdriver that was light, easy to use, ergonomic and durable. Most are not durable and we have bought many different models; for most battery screwdrivers, the forward/reverse switch is the first thing to go, in an industrial setting. We chase threads with a modified tap, so, forward and reverse many, many times is what we put this thing through and so far it is up to the task. Time will tell if it will hold up; I will update this if it starts to fail.

The Milwaukie M4 1/4 inch hex screwdrivers I recently purchased are for the most part great and Industrial so far...but...one of them has a "sticky" trigger which is worrisome on a rapid "forward/reverse" action I use constantly to avoid screws trying to bind/freeze up in roughly tapped metal chassis...otherwise,good workers. The price seems fair enough,but because the one unit sticks on the trigger..I wouldn't mind swapping out with another.

Best cordless screwdriver available. The batteries last a long time, and it has the power to drive 2"+ screws without predrilling. The clutch goes from very light (3.7 in. lbs.) to heavy (23.7 in. lbs.) and the motor stops with a click when the torque is reached.
