Help with specifying?
(OP)
My company produces some lumber products that require us to drill 1 1/2" deep holes 5' deep. Currently we do it by using hand held drills, which is our bottleneck. We looked at using a Milwaukee Core motor(4096), which is extremely close to what we are looking for but lacks the torque(162 ft/lbs) to fully accommodate our needs. We have have a extremely small work area and we need to operate 5 of these simultaneously. While gear reduction is an option, I would prefer to use the motor directly. Ideally, what I'm searching for is a 3 phase motor, that has a drive rpm of 700-900(faster will exceed the capabilities of our drill bits), while maintaining aprox 250 ft/lbs of torque.
Perhaps I'm asking in the wrong place, but maybe someone can help steer me in the right direction. Any help would be appreciated.
Thanks,
Chris

RE: Help with specifying?
250 lb-ft at 900 RPM is 43 Horsepower. The Milwaukee Drill is rated at 4.8 HP so something is wrong. Is it possible that the torque figures are wrong?
RE: Help with specifying?
HP = (Torque x rpm) / 5250
4.8 = (T x 900) /5250
T = 28.
So currently, based off of that I'm currently at 28 lb-ft, and would like to achieve 40~.
