I've started using radian tools for my home workshop and they're a cut above the rest (no pun intended). They're so much better than trend cutters which I've tried in the past with no joy. I bought it mainly for routing channels for truss rods in my guitar neck builds, it is perfect for that application. The cutter was packaged very well like my other radian cutters were, they come in their own box to keep them safe when you're not using them which is a massive plus. Cuts smoothly and leaves a good finish.
Fantastic bit, cuts very smooth without any issues!
