I'd stay well away from those.  I want something I can pull the trigger 
and go till done. I'd find that 10/30 to be really frustrating when 
raising a tower. A drill motor rated for mixing should do the job. 
That's why they are so much more expensive.
If working a regular motor hard as with a winch that has a friction 
brake, 30 seconds may not be enough cooling time.  That was about what I 
used on the biggest Dewalt Lowe's sells. I burned it up in less than 5 
minutes drilling 3/4" holes in 1/2" steel.
I had drilled 1/2" With my battery powered, variable speed, variable 
torque, (hammer capable) drill motor  I was enlarging the holes to 3/4" 
with the big drill motor.  Even though the battery powered motor was 
smaller, it did get hot, but I was able to just pull the trigger and go 
till the holes were done and I didn't wait between holes like I did with 
the big motor.
