CNC Shark Forum

First post on this forum! I own a CNC Piranha, with a Bosch Colt router.

I've got some fine detail things that I want to cut, but I'm afraid to try for fear of breaking my bits. I have a 1/64" diameter EM and a 1/32" diameter EM. From other people's experience, what feed rate should I use working with dark walnut. The cut depth of these bits is probably 1/16" max, but I was planning on doing a couple of passes anyways.

Any help would be greatly appreciated!

I've used a 1/16" and 1/32" bit for some furniture models, but never braved anything smaller. I wouldn't take more than 1/2 the diameter of the bit for a pass depth. As for feed speed go ahead and use the same speed you would use for a 1/8" or 1/4" bit. Run the little bits at full router rpm though. If the bits are single flute then cut the speed in half.

Thanks for the reply 4DThinker! I've seen you post in several different threads and see that you're pretty knowledgeable...thanks for the help!
