Selecting router bits for your CNC can be confusing since many brands, types, and sizes are available. 

When buying bits, I look for three things:

1. Profile accuracy

     - Is the v-bit angle accurate?

     - Does the v-bit have a sharp, pointed tip for details?

     - Does the ball nose, core box, or round nose bit cut a nice smooth semi-circular groove?

     - Is the cutting diameter accurate?

2. Performance

     - Does it produce a clean, crisp cut?        

        (Some types of wood are hard to route cleanly, so it's not always the bit.)

     - How long does the edge last?                             

        (It's essential to use appropriate feed and speed rates since the wrong settings can quickly dull a bit.)

3. Price

              - The cost of bits adds up, so saving a few bucks is nice, but quality and price are usually related.

 

Below are some of the bits I frequently use in my shop and classes. They have performed well in both situations, especially when working on a small-format (benchtop) CNC machine.

I've found much truth in the saying: "You get what you pay for."

That said, some brands are priced very competitively and still perform well. I've started using some of them regularly and have included a couple of them in the list below. ​
