I'm trying to assemble myself my first set of end mills - and the more I look into them the more confused I get. Diamond bits, 2 flutes, 4 flutes, 1mm, 5mm, 10mm, ball nose, v cut... where do I stop????

Can anyone recommend say 12 bits - maybe more maybe less - that would do me for a variety of materials like wood, plastics, aluminium, fibreglass board, PCB etching? I haven't got one specific use for the machine and plan on using it for a variety of projects which would include cutting out panels and carving.

The machine is hobby grade but stronger than an OX or Shapeoko. I'm going to be using a 2.2kw spindle with an ER20 collet.

I'm expecting to be breaking the odd bit due to my rookieness so I don't want to be spending a fortune on the best coatings, materials etc...

Sorry if this has been asked loads - I epect it to be but I couldn't find the info I was after.

Cheers :)
