Bjarte the Souix and the Milwaukee close quarter drill are identical.
One costs more than the other. The rear bearings in both have a
tendency to wear out from sanding dust. The back bearing is not packed
in grease as are the front bearings. You can forstall the wear out
replace problem by blowing out the rea bearng (and for the at matter
the front) periodically with compressed air.

You can get the Milwaukee on ebay for about $70 sometimes less. They
seems to be easy to lift and pawn shops offer them. There are cheap
knock offs on ebay. They run around $25. Almost cheap enough to be
considered disposable. You can tell the knock offs because in the
pictures there is a black tab near the handle on the cord. Some pepole
buy the knock off and when it is gone get another.

I have all three types. All work well. The Souix has had to have its
switch replaced twoice in three years. No bearing replacement but they
are available at Boca Bearing in Florida for about $11. Darryl
