I have got a couple of countersinks, both HSS-E.
One 15mm plain shank, one 19mm Weldon shank
Both sharks are about 50mm long.
I would like to have both shanks reduced to 12mm.
Alternatively a hexagon grind would be fine.
Presumably some sort of relief/chamfer on the ends.
Happy with +0.5mm/-1mm on the 12mm dia, as concentric as is practical.
