I recently bought a made-in-China knockoff of the Kurt D-40 4" mill
vice, this being a nice size for my Millrite vertical mill. What I got
is an Enco SR425-7241, which was on sale plus free shipping.
Price comparison: The same Enco catalog quotes $575.00 for the
plain-base D-40 and $86.95 for the corresponding import, so the price
ratio is 6.6 to 1.
I had been looking for a used D-40, but they are far from common, so
gave up and I got the import.
The import vice seemed to work just fine ex box, although the finish
isn't quite polished.
I took the vice apart, and all the expected parts are there, but some
are crudely made, and there was some gritty swarf in the cavities.
The half-sphere that goes between the angled driver and the back of the
moving jaw block was very crudely made, with a big machining center pip
that dug into the face of the angled driver. Cleaned up with a file and
The angle was left as cast, so I flattened it with a file, so the flat
side of the hemisphere can slide around freely. The spherical socket in
the moving jaw body was also as cast, not machined. Mated the socket
with the hemisphere using some Clover grit-in-grease and much elbow
The 8mm square key that fixes the stationary jaw to the vice body was
too big for the slots, and had been forced into the slots. Carefully
filed the square key down a bit, so it's still a push fit, but not a
Deburred everything, even the hardened jaws. The burrs were not hard,
and there was thin decarburized layer, so I was able to ease all edges
All this took two or three hours. The vice has a very firm grip on flat
stock, and the jaws do remain parallel, but I don't think that the
movable jaw will tilt from side to side much. I don't know how much
side-to-side motion the Kurt vices can manage, but this is a claimed
advantage with stock that is tapered.
Now, the long awaited perfect used D-40 with swivel base will turn up.
