I see a spoon bit on the left of that line up.
A big fan of those over here.
Very rare these days and some that come up are sometimes too old, worn and mangled to use, but spoon and the older shell bits are the oldest type of metal drills known ............. Good ones work beautifully and can be controlled into any angle once the knack of starting and controlling them is gained..... and that's what puts a lot of folk off.
They can be set to remove a heap of wood quickly or cut slowly, cut on either direction, can be angled to suit chair spindles and spoon bits leave a smooth, round base in the hole
Dozens of generations of woodworkers weren't wrong.
I shall watch this with some interest to see what comes up
good luck
