I have the 28 volt Milwaukee 90 degree drill and the winch bit, it sends the main up on our 40.5 very quickly with more than enough torque that I don't switch to the second speed on the winch to finish up. I can get up to 6 hoists on a single charge of the 28 volt battery. The drill is also more than capable of sending my 175 lbs to the top of the stick without breaking a sweat using the jib winch a Lewmar 48 in first gear.
