I put a collet holder chuck in the noname mill drill a while back

a regualr
wrench on to tighten and loosen quickly and easily. I like it so
much I
bought a similar one for the RF30. It works pretty good, but there
are
no flats on the body for a wrench. That means I still have to flip
the top and hold the pulley when tightening up a collet. Its tight
enough for the small stuff, but when I was doing some heavy (for me)
face milling with a 1" end mill I found that it seemed to walk up in
the
collet. Holding the pulley I really have no way to judge how tight
I am making the collet, so I figured I'ld mill a couple flats body
of the collet chuck so I can use a wrench like the one in the
smaller mill
drill. (never had a mill move in that one) Any suggestions?

I mean besides going back to using the straight R8 collets.
Obviously
I'll have to use them to mill my flats, but then... For the most
part the convenience of using the collet chuck is a HUGE time saver.

That part doesn't need to be hardened to a fair-thee-well, so it may
not
be "tool steel" per se. Can you file it? If so it's not that hard
and,
you should be able to mill it with HSS. If a file skates, or if you
don't have a rigid enough machine to make it work, can you get at it
with
a bench grinder? Can you disassemble the thing and _then_ get at it
with a bench grinder (this would relieve any anxiety about getting
grit into the works).

You don't really need flats -- it may be easier to get a nice hard
drill bit and make a few holes, then make a matching wrench (I don't
know what you call it, but it would be one with a semicircular gullet
and a reasonably hard pin that matches the diameter of the hole).


I think that fits the def. of "spanner" wrench.

Try "Pin Wrench"
