### ⭐⭐⭐⭐⭐ 







  
  
    I just hope I don't do something stupid and break it
  

*by S***S on Reviewed in the United States on July 5, 2015*

I had broken my regular 1/8" up cut spiral bit so I used this O-flute for clearing out the flat areas of a sign I was making out of pine.  Everything else being equal, the edges came out much cleaner.  A lot less clean up of the fuzzys.  I had been using this bit exclusively for plastic, but now I am ordering it for wood as well.  I just hope I don't do something stupid and break it... it is much more expensive.

    Great bits, no need to look for anything else.

Awesome for HDPE.  Razor sharp, these make very smooth cuts even on my cheap CNC machine.
