I want to cut down the end of my 10mm carbide sizing die. This will allow the die to size a hair more of the case getting rid of the "glock bulge" I tried cutting the end off with a cutoff wheel, tried grinding it, both a no go. I will try and take it to a machine shop tomorrow, will they be able to cut the end off easily so it doesn't cost me an arm and a leg?

Doubt it. The hardest most impressive cutting tools I've got are carbide; unless you find a shop that has diamond tools, they're probably not going to be able to do anything to it.

You know anybody with an EDM? :laughing:

Of course, I've read that if you try to cut carbide tooling with an EDM you risk the chance of fracture.

The next option would be to go with a regular die and trim it, then back to using case lube=ugh.

try calling the guys that made it.rcbs has modded dies for me at no charge.

If I understand what your saying I think a shop can do it. They can put it on a grinder and spin it down.

You wouldnt happen to have a drill big enough to chuck it up in it and a chop saw would you?

He already said he couldn't touch it with a grinder.

You could take a small amount off with a chopsaw blade. Wouldn't be worth the time though if it is much. If you are just wanting the length shorter any machine shop can hook you up.

a machine shop could probably grind it for you, and i'm not talking abrasive cut off wheel or angle grinder.

i'd contact the manufacture of the die first to see if htey can help.

How much do you need to cut off, just a hair? I've had the need to cut an end mill in half and found that a diamond cutoff wheel for a dremel worked well. It took a while and was trashed afterward, but it did cut it. They had diamond bits for shaping. Use water to lubricate.

Of if it doesn't have to be a precision cut, how about a diamond tile cutting wheel for an angle grinder?

A lot of effort for a ten dollar die. :laughing:

Eh, Apparently the heat from the grinder made the carbide brittle, I dropped it on steel from a height of 12" of so and the carbide insert shattered. :( I bought a Redding GR-X die this morning. This is a push through die that shoves the entire case, head, web and all, all the way through the die,not in then out, sizing it all the way.

Carbide's pretty brittle stuff normally, at least, carbide tooling inserts are. Really hard, very wear resistant, but shatter easily if mistreated.

I have diamond and cermet tools to cut, but it sounds like our surface grinder would be best.

Maybe I will bring you my 9mm die to do the same thing...

I thought your Glock didn't bulge brass?

Huh, I have no issues with my 20sf.

I have never shot factory ammo or anything other than my reloads out of mine and have never had a problem even with hot loads.

My brass fits in the two other (non Glock) 10mm's I have access to. You have a lemon.

http://www.pirate4x4.com/forum/showthread.php?t=809994&page=2&highlight=It doesn't but all the brass I just picked up to reload is bulged. Thanks for playing. :rolleyes:

might be easier to cut down the shell holder if it's thick enough :flipoff2:

When I read this I thought, you want to bring him your 9mm die to let him drop it on a piece of steel from 12". I laughed. I need a nap.

There is a grinding wheel for standard bench grinders for sharpening carbide tool bits.

So they should be with a Rc of over 60 most times... ;)

We have it EDMed to size and grind to final shape on the stuff we do, and yes its flood cooled during the grinding with a light feed level so it takes a while.

D.

I once had a problem with a .38/45 conversion. The guy who gave it to me said he couldn't size the brass for the chamber. I determined that it was .023 too long. I used an automotive valve facing machine (the end that tips the valve) and took off the .023. Worked fine after that. Hope it helps. p/s the valve machine has oil cooling for the work....

Nope,I quit trying to redneck engineer it and bought the die I was talking about on post 12

BINGO! We call them Green Wheels (they are green!) and use them in our shop to shape carbaloy carbide cutters for our lathe.

Don't even try regular grinder wheels :laughing::laughing:
