When I was a 1st year apprentice I used one like yours for "close quarter work" on a old Navy ship, the Old mechanic had this drill in his tool box. We just realigned a pump to the old foundation, so had to drill & ream the misaligned holes, but the top clearance didn't allow a drill motor, used short drills/reamers, assembled in place, used 2x4 as a lever (4x4 too fat) to apply pressure, he applied pressure on the old-man & I cranked the ratchet.. it worked great..
