On the subject of cut offs I use Dewalts and sure they work but in each case as I use them they never last long .A wile back i found a used cut off the arbor size was to large for my chop but i aliened it and it worked and worked and i have lost count how many cuts i made and still have it. i sure wish i knew the company who made it . I think it was a worn down king size cut off as i found it in a utility company trash container.
My drill master from harbor freight lasted at least 6 months, it had about 10 hours of the motor actually spinning and it burnt out over the weekend. I upgraded to the Chicago tools we will see how long it last, if only 6 months the next one I will pay 9.99 for a two year replacement guarantee.
Battery powered or electric? I have a Ryobi electric cut off, has worked great for over a year..But my ryobi battery power dies in about 10 minutes.
Copper Head, are you talking about the cutting wheels or the chop saw itself?
Thank you FJ The cutting wheel - Heck I find saws in the trash that work - Like i have this mistery cut wheel thats still cutting pipe after pipe ( STEEL )
It was a find that i had laying around months and one day i needed a blade . I wish i had a box of them I feel it used to be much larger and this was the toss out cause it got to small @ 10 inch , Is that possible ?
I just found a big cut off blade this thing looks 18 to 24 round the center is messed up for the arbor , Using a old cut off I rigged it up and now i am cutting pipes with what looks like a very long lasting blade for the 15 amp Hitachi. I had to remove the shield & when I cut I have to really pay attention and hang on for life, has a gyroscope like feel. This is a real gray area for safety !!

Nah, its gonna be a Red area soon.....
Hell, never take a guard off a grinder & never use a disc thats too big for the grinder, the centrifugal forces are pretty big & add up exponentially with a too large a disc.
Also, as you noted the gyroscopic forces add up pretty quickly, the revs are far too high.
That & no guard is asking for a accident, grinder disc accidents are really bad, they never heal well & leave a lot of scar tissue.
I make use of the guard as a lever so I can maintain a steady pressure on the grinders motor.
You can use worn down discs on a smaller grinder, ie a 9 inch disc thats been worn down to 5 inches in a 5 inch grinder is Ok.
Actually I have a small mark on my 9 inch grinders guard. So that when its won down to that mark I take it off & put it on the 5 inch dia grinder disc stack on the wall, on a nail.
The disc is most efficient at its top revs, so let the grinder get up to top speed before touching the disc to the work peice.
I think the OP's found disc may be a worn down asphalt slitter disc. Or for stainless steel. They work real well.
better rethink - but this could cut all my ac compressors for like zero money - SO - I could suit up to the hilt hard hat face mask lines mens gloves . I can see it will take some time till this blade get small that will be allot of danger time
