Probably OT - oddball bits for brace

Oddball bits for brace 2

>These are older acquisitions. They're clearly drive bits of some kind, but what they drive I know not. I suppose they could be for driving taps, but the size would have to be very specific, and large too. Galvanized pipe taps?

>These are not mysterious, but I'm posting them here for the entertainment of those too young or too sheltered to have encountered them before: pipe reaming bits, for reaming galvanized (or black, for that matter) plumbing/gas pipe after cutting it, so there's not a "lip" inside to interfere with flow.

>Bill,

The nut drivers are for driving square nuts instead of hexagonal ones. I'm not sure when square nuts lost favor, but they are prevalent on old farm implements, etc. I very rarely see nut drivers for a brace that are for hexagonal nuts.

I think the other bitstock is for grinding valves.

>With no relief hole for the bolt I doubt they are for nuts. Rather they would be for driving lag screws. I have one that my dad had and that's what he told me it was for. The one on the left is for square head only, the one on the right with the two notches could be used for a hex head as well.

Used to use one of thoes for electrical conduit

>My wife's little digital camera is not very good on close up shots; I cropped the source photo for the earlier post to show just the head of the bit.

I doubt that it's a spanner, in the sense of something that could turn a nut - the various pieces are just sheet metal, and it's held on the shank with a cotter pin, so it wouldn't take much torque. I think Jim Crammond is probably on the right track - something designed to hold/push a fairly freely turning part, as for valve grinding.

What it is NOW is a piece that my sons or grandchildren can puzzle over when they clear out the old man's overstuffed shop.

>it is an adjustable spanner driver for spanner nuts. Think split nuts. I have sold a couple on eBay and they sell quite well

AFAIK, There for driving...
