I am trying to cut some 3/8" sliding dovetails into the edge and end grain of different 1" thick hardwoods. The problem I am having is the bits are breaking at the neck just above the collet when I am trying to cut the female groove. I am really going slow and goodness knows I have enough horsepower and a stable platform (Porter-Cable 75182 in a Woodpeckers VRL II lift and a Woodpeckers Incra LS fence system on a custom built table with a 2 hp dedicated dust control system).
I have tried cutting the slot partway, vacuuming out the slot, and restarting the route, but as careful as I am there always seems to be an irregularity around the place where I stop and restart that makes the sliding dovetail catch and not slide smoothly.
Open to suggestions including successful techniques or recommendations on a different hardwood to try. I have been trying to do this with Bird's Eye maple and walnut.
Thanks,
Kurt
