Freud 20-109 1/2" Diameter 90 Degree V Grooving Router Bit with 1/2" Shank, 2-1/4" Overall Length - Perfect for Woodworking, Cabinet Making, and Decorative Edge Profiling

I made the MPCNC from V1engineering, and I use the Dewalt DWP611 which has a collet diameter of 1/4". And I needed a good V groove bit, I have read great reviews for Freud, Albiet it is one of the more pricey brands. I can't speak to the longevity, or the sheerness, but I can speak to the value. I have used this for various cuts at various depths and it feels well built, well designed, the chips go up the flutes properly, the cutting surfaces were sharpened and it has the best packaging I have seen for a bit.Will have to try to break it and see if I need to change this review. (not intentionally, but through use)
