I've been using a 2" Walter Zip wheel to cut off M14 Hex Nuts & Bolt, at approx 22,000 RPM. The material of the wheel is some sort of fibre or kevlar. Does anyone know of a better wheel that can cut faster? This wheel takes horribly long. What about the metal wheels, I think called Diamond Cut Off Wheel.

 

That's a tiny wheel. Get a 4" wheel and a angle grinder. Use a wheel specifically made for the material being cut.

M14?
you need a torch, not a wheel.

 

I was wondering that. It was taking way too long. I take it then you are refering to a plasma cutter. Too bad I couldn't rent one. Anyways, to speed it up as much as I could, I actually used an old fashioned hacksaw, and it went much faster. Those end bolts were actually positioned so you could fit the hand saw.

I did get through them, but I was actually cutting through the diameter of the M14 Hex hut & the rod through it, so it with pretty thick...the die grinder did about 80% of the work - I had to cut it right at the washer, and in fact it ground down 1/4 of the washer, just to make sure I didn't finish cutting and there were these left over bits that wouldn't let the bolt slide out through the strut.
