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?

These guys tend to sell more than most:

There are others, but these guys have been in the game
for quite a while.(1945)

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

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.

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

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