Help with milling tools ID please

It is called a tap, used for making nuts. Looks like a pipe tap, though it is hard to say. Find out what pipe size it is for, even by just going to home depot and trying it on different pipes.

#1. Is not! Alien anal probe...right handed! #2. Goth cheek implants. (Upper or lower) #3. Carbide tipped belly-button piercer for teen-aged girls. #4. Dental tools for hamsters. #5. Square pegs for Gunner's round holes

1. if you cannot stand sarcasm, stay away from newsgroups.

number 2 - look in kennemetal catalog number 3 - dead center number 4 - indexable boring bars number 5 - carbide tipped cutters.

only number 4 is likely to be worth more than a dollar or two

#1 is a large pipe tap. Measure the diameter, the pipe size is about

#2 Are indexable carbide tool holders, I don't recognize the exact configuration. Probably used on a larger turning center.

#3 is a dead center, used on a lathe, probably Morse taper. Should be marked with a number from 1 to 5, looks like a #3 or so.

#4 is a collection of boring bars with indexable carbide cutters, used on a lathe or a boring head on a milling machine. Measure the diameter and length.

#5 is a collection of brazed carbide insert lathe tooling. Measure the bar dimension to get an idea of what size they are. Exepct to see dimentions like 1/2", 3/8", etc.

Whole collecti> Hi, I got a huge lot of machining and milling tools at an auction,

No, no...just having fun off the main thread. You'll get perfect answers here, looks like Royj filled out the list. I thought my list was more fun, tell me you didn't smile...

Interested in selling the boring bars?

Let me know and we'll go from there.

For a sense of humor, try McMaster-Carr, they have everything. Get as good a one as you can afford. Bob

According to leeana :

A large pipe thread tap. The name "RIGID" is normally associated with pipe threading and wrenches. It should have the size stamped into the shank.

Kennametal parting/grooving insert holders which mount on rather large bars which are not included in the photo. Get a copy of the MSC catalog and look there for what they fit.

That is a Morse taper center -- with what looks like a carbide tip. I've got no clue as to the size -- but I *think* that it is too large for any lathe that I own.

Boring bars -- as your photo name suggests -- mostly carbide insert type. Some look too large for my lathe, though the smallest three or four may work. You really should include a 6" or 12" scale (ruler) in the photo to give an idea of sizes.

Brazed carbide insert lathe tools. All seem to be left-hand ones -- less commonly used than the right-hand ones. Again, how about hints as to the size?

Certainly we don't have enough information available as is for you to have a chance of re-selling them, which I presume is your intention.

#1 is a pipe tap #2 is an indexable something or other (check other posts) #3 is a morse taper dead center, possibly with a carbide tip #4 are indexable lathe boring bars, large size #5 are AL (style A, left handed) brazed carbide lathe tools, C5 grade carbide, 7/16" shank Hint: on that one all of the info is in the number AL7C5--AL is tool style, 7 is shank size in 16ths of an inch, C5 is a grade of carbide, the only other one you would see is C2.

These all appear to be lathe tools, but they could vary from a large CNC turning center (#2 and some #4) to #5 which could be used on a relatively small bench lathe.

H> Hi, I got a huge lot of machining and milling tools at an auction,

inserts. For turning on a lathe.

Brazed carbide turning tools, for a lathe.

So, no milling anything here, but all except #1 are for use with lathes, pretty exclusively.

I might have some interest in some of the boring bars, are you going to sell this stuff on eBay when you get it sorted out?
