CNC Router Bits Explained: The Best Bit To Use

1. Great video, espeacially for newbies like me

2. Does SpeTool have specs for the spiral change? I don't see any info on this on their up/down bits. If there isn't a spec given can you just use a micrometer to measure the bit on where the change occurs? I would assume it would be visually obvious on where this is on the bit. If we're still on track here, Is that value then used for the routers plunge rate?

3. Great Video !!

4. Where do you purchase your compression or down cut bits

5. Is it possible to reverse the rotation direction to turn an up cut bit to a down cut bit?
   Also, can you do the first top pass with a down cut but and then do the bottom pass with an up cut bit?

6. Learned a lot about these bits and look forward to learning about other bits like V Bits. Thanks! ?

7. I use single flute straight flute bits for almost everything. Cuts are clean and smooth top and bottom.

8. Thank you for sharing this info, helps to shorten the learning curve.

9. Hey Andy! I have bought into the Shapeoko Pro XL & were I to get one of these compression bits, can I use it with that machine + the carbide router safely on more than MDF & still benefit?

10. Andy – Shapeoko owner for 3 yrs now. Both my 1/4" upcut and downcut bits are discolored and I assume are getting dull. Time to replace them. I like your video on "Best bit to use" and I have a question. You show the Max Depth as .52000" for both bits. Bits&Bits shows the max cut length of 1". Why are your depths so conservative?

11. Thank You that was extremely helpful for me being a new bee to CNC . Bought the Shapeokoe PRO XXL.

12. i subscriber to your channel i like your videos take care

13. Very interesting about the spiral change point – Unfortunately many of the router bit manufactures dont seem to specify this piece of information!

14. Great video, bro.
    Very informative.
    Just wondering: Do you use a spoil board on your machines?
    It seems that you are obliged to replace the machine bed slats – on a regular basis, otherwise.

15. I have a project that needs a triangle cut out of the center with sharp corners so I am thinking of using my 10degree engraving bit to clean up the last bit of the pocket. Any other suggestions? I cant find any videos on using engraving bits on the CNC for wood and super fine detail. My tapered ball nose wound work here…has to reach .505 down before cutting a .180 deep clearing. Hmmmm

16. Super helpful video! I appreciate the effort you put in to both explaining and showing.

17. Can you do these deep cuts on hardwoods with the compression bits

18. Great video, and super informative! Glad I watched.

19. Great info here Andy

20. Great video… I was looking for exactly this information earlier this week!

21. Very good information Andy!

22. Andy have you ever done a video on doing tool changes using the bit setter and bit runner..that might show the different screens in carbide motion 542

23. Can you use a downcut bit for the first pass and then go to an upcut bit for the final pass through the part as a way to get get a clean top and bottom surface, or will the chips being ejected on the last pass with the upcut cause issues with the top edge of the part?

24. cleared up a lot of misconceptions I had

25. Sounds like a bit i need ?question did you or do you recommend plunge ramp in with that bit and the others.

26. My Shapeoko Pro can handle a 0.25 inch cut, as long as I screw my stock down.

27. Very informative buddy. Thanks for putting it together and breaking it down to my level (kindergarten) ???

28. I am a metal worker, never know this was a thing with wood routers.

29. Thanks!

30. Great video. Love the content, bro. Thanks for sharing.

31. That was great. Very informative and explained perfectly. Thank you!

32. Great video bro. Still fine tuning how I do things after a year.

33. 3:51 you and me both brother
