Review on 🪓 High-Precision Serrated Forstner Bits - 4 Inch and 8 Inch Sizes by Brian Sage

I use this forstner bit mounted in a tailstock chuck to drill center holes in small hardwood salt shakers. That works fine. The sides aren't as smooth as other bits I've had and one of the cutting edges works harder than the other, but so far there's no chatter and the sharpness is holding up. Not great but good enough. I don't see any advantage with the sprocket.
