Hello,

I'm new to CNC machining. While I was looking for bits to buy from amazon and ebay, I found out that there are many coating options for the bits.
I mainly work on wood, and thinking about working on plastic. What are the pros and cons of each coating? Does AlTiN Coated bits work for wood? If it does, is it much better of uncoated solid carbide bit?
If someone have a website for the Pros and Cons of each coating options will be great.

Thanks,
Sayed
