View Full Version : Basic Tooling?

08-17-2009, 01:52 AM
I just recently acquired a CNC router and think i have the programming down pretty good but Im pretty lost on the tooling.
I will be mostly doing wood and foam with some aluminum here and there(maybe some plastic). What would some good basic bits be for that kind of material. A friend who knows some CNC suggested .25 and .125 bits in both end mill and ball nose. Does that sound reasonable? and is there any other bits that would be worth adding to my shopping list? (I would be ordering from Multicam tools in langley BC canada)

Forgot to add that it is a 3 axis machine with a Bosch router on it

End Mill and Ball Nose is the right way to go.
I cut all the material you were mentioning.
I live in Surrey, BC.


I have a 2' x 3' CNC router.

End mills are just bits with a flat end right? vs ball nose which is rounded.

Thats right about the end mills.
Buy carbide bits. They're twice the price of high speed steel, but they're worth it.

You might want to checkout KBC Tools in Delta.

Their prices are better.

If you're just cutting wood and plastic, then Busy Bee Tools in New Westminster is best.
Their bits are $5 to $7.

For your aluminium use two flutes instead of four (two cutting edges) that lests the chips get out of the way and stops them melting onto the tool.

Really they are both end mills.

End mills come in 3 basic forms.
Square end, Cuts a flat bottom with sharp corners.
Bull nose, A Square end with a radius added to the corners.
Ball nose, A Bull nose where the corner radius is the same as the end mill radius.
