Dremel cut off discs and hardened steel?

Hi,

I wonder if anybody here tried to cut hardened steel with those little thin cut off discs using a Dremel tool?
To be more presize, I'm thinking of getting a Scandinavian "Leuku" style blade and cutting off its point end at an angle to produce a "scramasax" reproduction (not exactly correct crossection, but a cheap alternative to a custom ordered blade). Anyway, it would involve cutting through about 1.5" of 1/8" thick carbon steel at (I guess) mid to upper 50s Rc hardness.
Do you think this is doable at all? How much time (and discs) could it take?

Thank you.
Alex.
 
Do it all the time and in a lot of cases they are the ONLY thing I can get to cut hardened steel.
I started using them 25 years ago to bob the hammers on my carry revolvers. This was before the Mfg. offered it as an option. Steel doesn't get any harder than a gun hammer. I still use them to cut tangs and reshape hardened blades.
 
Dremel makes three different kinds of those disks. Two are emery type, which break eaily and the one that I have found to work the best is their fiberglass re-enforced one. But they are expensive if you buy the dremel ones. I saw the same thing in a black&decker package at walmart for a lower price and 10 disks instead of 5 like the dremel. Make sure you wear a dust mask, they make plenty of it, and don't run it too fast or it will break down quickly.

Many thanks for the quick answers!
I will go on with this project, at least with design for handle and sheath. Actually I already spent some time researching scramasax handle and sheath construction and decoration, but almost gave up on the whole project due to the lack of suitable blade. Looks like it just got a second chance...

Those things are toys....what you want is some larger ones...like what they sell at MSC or Travers Tool that will either go on your bench grinder (make sure they have the right center hole size and proper diameter-mine are 1/2" hole and 6" diameter) or the same thing in 4" that will go on a air powered cutoff tool......You will get 100 times the life out of the big ones and accomplish what you started out to do. check it out. :)
PS- you can get air powered cutoff tools very reasonably at the same sources.....for around $30....make sure to ALWAYS lube them after every use. :(
 
I've got one of the air powered ones that Tom was talking about. Amazing what they'll go through. Cut through a D2 planer blade quite easily.

Were would I buy a cut off disc for a bench grinder? I am having problems cutting a few pieces. Is there any king of material that works best? Thnaks.
