I've spent about a half hour searching topics and came up empty. I'm looking for a sharpening service that can sharpen about a dozen different countersinks for me that I recently picked up as part of a sale. Most are damaged or have been poorly sharpened (zero flute not included). I don't even know of it's feasible these days but if it's not too expensive, I'd like to have them done professionally. I can sharpen drill bits but, for me, countersinks need to be done right, have the right angle and leave a nice finish. Not interested in suggestions on how to sharpen them, just looking for the name of a good sharpening service I can contact to see if it's reasonable. TIA.
