I have a horizontal mill with a 1" OD arbor. I've seen quite a few
cutters on ebay that have a 1-1/4" hole. These items usually sell for
very little.

Is there some sort of product I can buy that will allow me to use these
1-1/4" ID cutters on my 1" arbor?

Gary,
My Rockwell accepts several sizes of abors. 30 taper.
Can you get a 1.25 for yours?

My mill has a B&S #9 taper. Arbors (or most any other kind of fixture)
are VERY hard to find. They few that I have found sell for megabucks -
typically 2-3 times the price of NEW items that use more popular
tapers.

I'm looking for other options.

It's possible to make a special spacer for the arbor that has a step
turned down for the 1 1/4" hole cutters. Then a extra tall key and
your in business. We has one like that at my former employers.

Do you have a lathe? If so..simply make a bushing to go in the center
of the cutter. If you use a key..simply cut out the appropriate bit
of metal in your bushing. I do this all the time.

HOWEVER!!

A caviat...when you start running the larger cutters..it becomes
increasingly easy to bend your arbor as side loading on the cutter
becomes significant the farther away from the arbor, the cutting teeth
are. Be warned. Shrug

I made one for the same reason. I found 200 pounds of sharp cutters with
1-1/4 hole. I paid $35.00 for the lot so I made a step space that works
fine.

If you have a lathe and are concerned about the loading on your 1 inch
arbor, why not make a new 1 1/4 inch arbor. more work and more stock than
spacer bushings, but still doable.

If you've got a lathe, make another arbor. Not all that hard to do and
unless you're running production stuff with max speeds/feeds, you can
live without the keyway. I know this is heresy to some, but it
nevertheless is fact. I've been doing it for years. The collars very
effectively clamp the cutter in position. I'm assuming you're not
planning on running 3" or wider slabbing cutters; if you are, I'd use
the keyway.

But seriously, it does work and makes it pretty simple to make an arbor.

If one finds a 1" endmill holder to fit the spindle..one mearly needs
to make an arbor that chucks into the 1" endmill holder. This makes
far more sense than dicking around trying to get the taper dead nuts.

I would humbly suggest that if the OP has a horizontal mill, cutting a keyway,
if he wants it, shouldn't be a problem anyway :-)
