I burned a 3/4" spiral bit trying to plunge into end grain on a maple vise face. I didn't have a drill press, and the router seemed like the best choice. Didn't work, and burned the end of the flutes on the bit.
I bought a drill press and forstner bits for it; what a difference! So, my holes are cut, but I'm left with a $40 router bit with black ends on the flutes.
Is this worth sharpening? Where do I send it? I'm OK throwing it out (lesson learned) but if I can get it sharpened for less than the cost of a new one that would be a less wasteful choice.
Guide me, please....
