I do a lot of V-Carving with my CNC Signs. I use a V-Groove Bit to do this type of work.  One thing I have found is that one of the Best Bist for doing this kind of work is the Laser Point Bit from CMT.  Here is a link to the Bit I used. I got it on Amazon (Disclosure). I got this bit after I saw it recommended on one of the CNC Forums I subscribe to. It is one of the best purchases I have made for CNC.

Just before Christmas a friend asked me to make a V-Carved sign for them. Since time was of the essence, I went to my go to V Groove bit The Laser Point Bit. I have been using the same bit for over a year without any noticeable wear. I don’t know if this is unusual but I have a backup on hand for whenever this one finally bites the dust.

The tip on this V- Groove Bit is very sharp and pointed. Most V Groove bits do not actually have a pointed tip but the CMT Laser Point bit does. As a result it leaves a very clear line down the center of any V Carve cut.

When I make my V Carved signs I usually iuse  a paint masking film so that I can paint directly over the wood after carving without worrying about overspray.  I recently heard a bout a new method which does not use paint masking film. I plan to try it next week. The idea is to cut a bit deeper than normal, spray the entire board and then use a planer to take off the overspray. The advantage to that method is there is no need for masking film and the signs could possibly be made quicker. 

Paint masking film is used to prevent over spray
