Nice, sounds the way to go. After I thought of boring the countersink hole with a 10mm carbide endmill at 0.5mm step-downs so most of the material is gone then using the countersink bit, which prob would have been much kinder on my cnc. But your way seems a huge improvement on that. The countersink had to be around 10mm deep, so the full flute of the 25mm tool had to be in the hole.
