Hmmmm....
The drill motors run at 20023 RPMs idle. The high gear is 20:1 and the low gear is 60:1. So it should run at 1000 and 300 RPMs respectively. However, this is impossible because it would not free spin with the gearbox on. But you need to check the RPM to Torque chart to see the speed output at the torque output you want.
