I think the answer depends on if you are a job-shop accepting any and all
orders from customers or if you are building parts of your own design.   If
you are designing your own parts you can standardize on just a few gear
sizes, perhaps modulo 0.5, 1.0 and 1.5 are enough for any machine you'd
ever design and build.   Then for each size you need a full set of cutters
and an arbor to mount the cutters

You can find a full set of 8 for one size for about $100 more or less.  You
can even find them on Amazon.  Search for "involute cutter".

Here is an example .amazon.com/8PCS-Milling-Gear-Cutters-HSS
<https://www.amazon.com/8PCS-Milling-Gear-Cutters-HSS/dp/B07VFSQVJ5/ref=sr_1_9?dchild=1&keywords=involute+gear+cutter&qid=1595608530&sr=8-9>

But to buy every size cutter you might ever need in US and Metric size
would be quite an investment but buying just a few and then limiting you
designs to just those sizes in not bad.
