Review on Amana Tool RC 1108 Insert V Groove: Optimize Your Woodworking Precision by Anthony Hales

Read my Amana tool review - V-groove insert 45 degrees. Basically the same problems. The tip of this tool is so far off center it's ridiculous. It cannot be adjusted enough to center it. Save your money and look elsewhere. (At least the tip isn't broken on this one. But that's probably because I didn't use it.)
