Lathe bits??

[NJ Marty]

Got these at an estate sale with many other items. I filled 2 5gallon buckets with every tool and tap die ect off the work bench. This was in the last few hours of the sale so they wanted as much gone as possible. I cant id these items, but I think they might be for a lathe.

I think that first bunch are reamers...both spiral and straight cutting. They're for reaming a hole to precise size after drilling slightly undersize. Should have the hole size on the shank somewhere. Mostly used on a mill, rather than a lathe, though they're often turned by hand. I don't know what the second tool is.

He's right...Reamers

The first are reamers, the second is the movable jaw from a caliper. Tony

You got a large amount of money in those if u could part them out. I once bought a round tin about 12in across full of small brass fittings still I their packages for 5 bucks and figured up the prices at 1200$ some one was careless and wanted to just get rid of the tin as the swap meet season was over. rwd mo

LOL...I kept thinking those looked familiar, Tony, but couldn't figure it out....nice catch!.

The second item looks like an alignment jig. Probably for one special application.

Nah...Tony nailed it. It's the movable jaw from an old mechanical caliper. If you look close, you can see the vernier scale markings in the "window".

After looking a little closer and seeing the threaded rod they're on, I would have to agree. It looks like a Brown and Sharpe, like this one....

The first are called adjustable reamers, second is off of a height gage not a caliper, and the last I'm not quite sure about.

 

[cudamark]

The reamers I see in the photo don't look adjustable to me.

Cuda, the smaller black square head on the work end of the reamer is where the size can be tweaked a few thousandths of an inch.

Those are Government Reamers .. one size fits all!
