I had one identical, am sure it was a Wolf, was very low speed with masses of torque, the damn thing was dangerous if you were holding it..it nearly broke my arm when the drill bit got stuck... no way was it going to stop, luckily I managed to let go.
Should make a great bench drill though ... unless it spins the bench
she`s got a real bad attitude when she bites in , spin you round if you aint careful !
