Counter sinks

I need a countersink, but not sure which one. Would like it to be 3/4"
diameter. How many different angles do they make in common countersinks
found at the Borgs?

Thanks. I would have never thought to mark the bevels. Same garage sale a=
s the files, I bought 2 magnifying lamps, for $1 each. Here's my chance to=
use one.=20

Seated, aye? So, that allows for a beer, also, right?

I bought one of these a few years back and can attest to its
effectiveness.

Is there an easy way to sharpen a countersink's edges? I have several old ones, with 7 (small ones) and 10 flutes each.

I think a couple of the files are diamond files. They were a clock repairman's tools. I've used them to file hand/auger drill bits, but their edges are more accessible than the countersinks' edges.

Strong light, 3x reading glasses. Blue the bevel with a
Sharpie. Most jewelers recommend filing while seated,
not standing.

There are others, but these guys have been in the game

I've found that ones with an odd number of flutes work best.
The six fluted ones tend to make a hex shaped sink.
