I was at the scrapyard today and picked up some cutters.

Here is a photo:

http://www.drizzle.com/~dantzler/ima...cutter0007.JPG

The 3 thick ones have the following stamped into them:
UNION-CARD DIV
STW 8 x 1 1/2
BLADE-1122 R & L
WEDGE-W-25 & W-25L

The thinner one has:
Apex Tool & Cutter Co Inc Shelton Conn
53-60404 8X 742 46-820052-01
BLADES 65-66-11

It's a safe bet that the teeth are some type of carbide.

What type of steel are the blades made out of?

What is the typical use of these cutters?

I ask because I will be very happy if I got 40+ lb. of some type
of tool steel that can be forged into interesting, sharp things.

That's 404 (i.e., FNF) steel. Not very useful.

Can you elaborate? I'm not finding much with google. It is not
stainless.

Why is it not useful? What does FNF stand for?

Thanks.

Jeff, your link to the pic is stuffed. Is this link correct?

FNF stands for File Not Found, and 404 is the HTTP error
number for File Not Found. You presumably meant to refer
to http://www.drizzle.com/~dantzler/ima...op/cutters.JPG
rather than cutter0007.JPG .

Are those about 100 pounds each? Must have taken a few horsepower
to run.

I think you meant:

Looks like you got some huge horizontal mill tooling. I wouldn't expect
the bodies to be "tool steel", though, if they hold carbide inserts. if we
mean the same thing by "tool steel", as in, high-speed steel.

all I got was

I'm embarassed.

I changed the file name to something with less numbers than
my camera spit out and forgot to update the link.

The correct file name is:

http://www.drizzle.com/~dantzler/ima...op/cutters.JPG

I was hoping the saw bodies would be something tougher than
mild steel.


I'm sure they are - probably an alloy or carbon steel with good
properties in the Rc40 to 50 range, i.e., tending more towards tough
than very hard. Think wrenches rather than edge tools.

Judging by the rust and the grind, the inserts are most likely High speed
steel.

The bodies are probably hardened alloy steel. They have to be hard enough to
keep the saw tooth area (that locks in the insert) from getting dinged.

These are enormous stagger tooth horizontal milling cutters used to hog off
enormous amounts of metal.

The inserts are there for several reasons.
#1 it's cheaper,
#2 if you chip a tooth it doesn't trash the whole cutter, and
#3 Each resharpening makes the cutter slightly smaller. With this type of
insert, when they get ground too small for the job, the teeth can be moved
out one notch and reground to spec.

Okay. I thought for a bit that they may be carbide. Is the rust a giveaway
that they are not? i.e. does carbide not rust or rust differently?
I haven't gotten around to spark testing the inserts.

The bodies are probably hardened alloy steel. They have to be hard enough
to keep the saw tooth area (that locks in the insert) from getting dinged.

Any idea what type of steel or steels are used in these applications?
Ned suggested that it was likely a tougher rather than harder steel.

These are enormous stagger tooth horizontal milling cutters used to hog
off enormous amounts of metal.

What might the application(s) or industrial process be? The big cutters
have 2 keyways in the center. I can only imagine the forces acting then
these are doing their job.

That's a really cool design as I think about it.

Thanks very much for your insight, Paul. And thanks to the others who have
also responded to my question.

Try using a file on it, if it just slides off it is hardened. Tool
bodies are usually something that will harden nicely but not in the tool
steel price range. Probably 4130 or 4140 range. Nice mterial to have
around but you need to anneal it (or at least normalize it) to be
reasonable to work with.

Anneal on 4140 is 1500F, cool at 20F per hour down to 1230F Rockwell 13
Normalize on 4140 is 1600F, air cool. Rockwell 22
In your case, heating to 1600F and burying in a big bucket of vermiulite
for a couple of days would be as good as it gets.

These temps on that big a chunk of steel will be a real joy for the
average hobbist!
