I am new to CNC routing. I’ve got a Dewalt DW660 on order and would like to select some milling bits. I am familiar with drillman1’s (on ebay) inventory and would like to purchase from him. Initially I am interested in cutting plywood up to 3/4″ (which would require multiple passes correct?).
What type of a bit should I get? Do they wear out fast … in other words should I order a few?
Do you recommend any other bits for a person just getting started?
Thanks!May 21, 2016 at 1:39 pm #12571
As an example, drillman1 one sells 1/8″ carbide 2 flute end mills like in the photo I have attached.
Is this a good choice for cutting plywood?

Yes that is the one I use.May 22, 2016 at 6:29 pm #12701
End mill life depends on several things..generally speaking the more aggressive cuts you take will stress the blade and we at it down faster.. I usually tell my students not to take more than 25% of the diameter of the bit at a time no matter the material.
I have yet to make any cuts with my mpcnc, but I do have a denford mill in my classroom. 1/8″ end Mills usually get about 30-50 hours of use… but we mill everything from aluminum to acrylic.May 22, 2016 at 9:06 pm #12706
