Chris and I are trying to categorize the cutting bits based on the types of projects you can produce, to potentially create kits with all the end mills required.
For example:
Signmaking: 60 and 90 deg v-bits, 1/4" downcut
Relief Carving: 1/8" and 1/4" tapered bits, 1/8 and 1/4" upcut bits
Metal and plastic working: 1/8" and 1/4" single flute bits
Bowl Making, Guitar making, and so on.
What other categories might people find interesting or useful? Is there any combination of bits that are indispensable to you for a type of project?
In addition to those that you’ve listed, I use the 30° V bits that you sell for fine line engraving. The advantage over the 60° and 90° is that you can go deeper while staying narrow. I use ball nose bits for models, mostly 1/8". I also use a plunge round over bit for doing the edges of signs. I don’t use it much as I have a router table, but it’s nice to be able to finish a plaque completely on the Mill.
