Review on CMT 811 060 11 Straight Diameter Ply Groove by Sean Fabacher

Very clean cut and in contrast to another reviewer it is exactly 6mm. I used it to cut channels for 6mm carbon fiber reinforcement rods in a guitar neck. The square bars measure exactly 6 mm and fit perfectly into the milled grooves. I've only used this on Spanish cedar so far, so I'm not sure how it will work on hardwood. Next. flame maple.
