Tap it in

[Nubbyhands3]

These taps I have came from a company that went out of business in the 90s. Idk if that makes them vintage. But i would sure like to sell them or find someone who could sell THEM

The ones with the silver hex bodies are most likely thread check gauges and not taps. The ones with the straight flutes are reamers. I see at least one tapered reamer also.

 

[MShaw]

You are correct. Gages and reamers. What company were they made by?

 

[Nubbyhands3]

Precision tool. I believe. One says sheffield gage

 

[Nubbyhands3]

Most of them just have numbers amd letters or go no go which i havemt quite studied emough on.

Go-No Go gauges are precision fit check tools. When placed in location, the Go side should fit, and when reversed, the No Go end should not.

The tap marking gives the thread diameter in standard dimensional information and the thread pitch. In the case of one shown, it's a a tap for a 1/4 thread, 24 pitch.

Ok making a little more sense now. So what does one do with all of these.

Do I see that it is a Left Hand gage?

very specific market IMO, they may be a toughish sell . the people that would be interested would want to be sure they're in very good condition and not all rusted & buggered up I suspect

Used taps are a tough sell because condition is everything and any business will just buy new.
At least an effort has been made to protect the cutting edges on many of them by putting them in card tubes.

 

[Nubbyhands3]

I completely understand that. I dont think some of these have been used at all
