Creating Symmetrical Shapes Spiral Flush Trim

The 0.25" spiral flush trim bit available from Mobile Solutions is my favorite. The main advantage of this bit is that the bearing and cutting edge are extremely close and allow duplication from templates as thin as 11/416". The small diameter also allows duplication of more intricate shapes. One drawback to this bit is that the spiral design makes the bit put more lateral stress on the template compared to a standard flush trim bit, so liberal use of template tape is always recommended, especially on small and thin pieces.
