It has a straight 3/4" shank.

What I was hoping, is to be able to use it in my Bridgeport Interact
CNC mill for high speed work with spamm cutters.

1) Is it going to work well

I don't know. What gear ratio and what condition is it in?

1:6, it is smooth

2) What kind of grease should I use in it

Grease? If you are increasing the spindle speed, I would expect
an oil -- and hopefully the proper oil is listed on the label. If not,
download the manual from somewhere.

There is a great fitting on it

A Zerk (grease) fitting doesn't necessarily mean "grease me." You need
only look as far as a Bridgeport table without a central lubricator to
see "grease" fittings that should be oiled and never greased.
