Question: When you screw that cone into the wood, is it in so tight that you have to reverse it out or just pull it out? A drill bit gets rid if excess cuttings whereas the cone spreads the wood.
How about smaller pilot blades ahead of the main blades. I wish we could see a tube of the "FECON"...
Hey Kelly tree, instead of having such a massive draw down screw wouldn't it be easier to have more of a drill to keep the blades centered and turning rather than being forced into the wood by the force of the big o' screw? Just saying. Kan-Do
