Looking for 5/32 long cut end mill

[thegunny419]

I've been playing with the infernal search engine for an hour now to no avail--pretty much exhausted all the normally recommended sources--Enco, MSC, Grizzly, etc.

Does anybody know where I might find a 5/32 end mill with a length of cut of at least 1.0"?

Any help will be appreciated.

Unless you are cutting soft butter, a .156 dia tool an inch long is going to deflect A LOT, and probably break if much side pressure is applied. Not being a smart a$$, but maybe thats why you can't find one?

gzig5, you are probably right about that being the reason.

I think, however, if I can find one, I can make it work for my purpose which is drilling the trigger and hammer pin holes in an aluminum AR15 lower receiver casting. Very slowly...

Thanks for the input.

I suggest for that purpose, you would get better results by drilling undersize and reaming to finished diameter.

check MSC or travers tool

Jtl,
I saw your post on the "other" forum and if you want to save the reciever, clean out the bad holes and have them tig welded up or bore oversize and plug them, then re-drill from one side all the way through. Use the least amount of exposed drill that you can to try and keep it from walking.

I don't know how you need to fixture the reciever, but you might try drilling and reaming the first hole on one side, remove the receiver, drill and ream in a block of aluminum or steel, insert correct size pin in the block and don't move anything! Put the reciever back on the block with the pin through the first hole and drill/ream the second hole. Make sense? Could that work? Might be a tricky support setup for the second hole, but it should put them dead on each other.
Good Luck
