Never seen that kind of brace bit before. Looks like a type of flat-bottom bit, maybe a little worn down.

I wonder if these were used for the stepped screw holes in saw totes.

I can’t wait to get back to making mine. (So many shop projects in limbo. Ahhh!)

They look like Forstner bits.

Yeah but with square shanks? For hand braces? I’ve never seen them before.

I’d love to have some, but I doubt you can buy them.

A brace chuck adapter could probably be made for use with newer round shank Forstner bits.

See the drawing of the 1886 patent for Forstner bits:

Thanks. Never looked into his name before. Didn’t think Forstner bits were that old.

It’s clear they were flat-bottom bits, but now I realize Forstner is pretty much the monopoly on that meaning.

Those bits were invented for the armaments industry, to make flat-bottom holes in the wood structure of the guns.
