I've been using some cheap 7" cut off wheels on my dewalt 10" MITER SAWhttp://www.ebay.com/itm/20pcs-7-x-3-...item2324b76870THEY CUT VERY FAST and the heat is not that bad because the blade is super thin. Only problem is they are 3" too small to begin with and after 5 to 10 cuts in 3/4" by 1.5" bar they get reduced down to about 6.5" in size which makes them too smallso I looked for a 10" cut off blade and found this:http://www.mcmaster.com/#45615a148/=u5j1ufthey are $6.43 eachDiameter 10"  Thickness 0.040"I've never seen a 10" cut off wheel what tools are they designed for?Anyone ever use them in a 5000 rpm miter saw. The specs say they are rated for that speed, but I'm still pretty aprehensive about them falling apart and hitting me. thanks for any insight.PS, did a search and didn't find any info on these big thin blades.Also have tried cutting this with a 14" 1/8" thick abrasive metal cutting blade on a different saw and it makes a big burr and gets hot and the blade wandersIt is too thick to safely cut with my northern tool dry cut saw without fear of destrying the blade early. this is where I am at now.
Reply:I built up the bed of my miter saw about an inch and now the 7" blades can be used till they get down to a small 4" diameter, so issue solved for now. Maybe after I use up all my 7" blades I'll toy with some of these huge 10" blades. I can say that after using the thin 0.40 disks I will never go back to the thicker kerf disks that are 3 times as thick!I've gone through 5 blades so far and none of them have had any issues.
Reply:Generally I find that if I don't put too much pressure or (downforce) on the "zip" disk that they last much longer. Being such a narrow kerf will inevitably make it less sound than their more robust brothers, know your tools/materials and approach accordingly. Once the disk gets too small, I move it over to one of my hand grinders. Without deflection or twist and excessive downforce the zip disk should have no problem maintaining integrity, I do not remove  guards on any machine that has them, too many disks have blown apart for one reason or another, but if you do insist on removing the guards, stay out of the line of sight of the disk, it could be a bad day. Pick up a couple of these disks so that you can experiment on best practices. Taking a few moments for the sake of safety is the best investment you can make.

Reply:Thanks for the comments. I agree 100%. These thin zip disks are so much better than their fatter cousins, the only drawback is they wear down faster, but faster cooler cuts with less burrs far outweight that one disadvantage!

Reply:So we've been cutting a lot of steel lately and here are some observations with this set up7" blades work great and dont' need blade stiffeners. I haven't noticed any blade breakage or safety concerns. when I switch over to 10" blades I'll try to remember to report back.Material cuts faster when Vertical vs Horizontal. for example I was cutting some 4x4" angle 1/4" wall. The abrasive blade worked great until it hit the bottom flat part of the angle. I guess too much friction slows it down too much. You can always flip the angle, but of course getting the two cuts to line up in the center is hard. Plastic guard did not melt on wood miter sawsaw dust collection bag does melt, so remove it before proceeding.the dust is annoying so I cut outside. I'm going to wrap some furnance filter material around the motor air intakes so the dust doesn't get into the motor. We often bundle 6 to 8 bars of metal (1/2x1/4"  1018 steel) and cut them at the same time. I hate to admit it, but this saw works better than my more expensive dry cut saw which isn't rated for bundles that thick. Other than the odd 4x6" aluminum rectangular tube I probably wont' be using my dry cut saw that much anymore. It is just too tedious to cut metal bar one at a time vs being able to cut a whole bundle at once. Plus it is not a big deal when a worker busts a $1.50 abrasive blade vs a $65 dry cut blade. So lesson learned sometimes a wood saw cuts metal better than a metal saw. who would of guessed? Both saws cost around $250 Northern tool 14" dry cut vs Dewalt 10" compound miter saw.
Reply:For a chop saw I highly recommend these http://www.ebay.com/itm/Makita-14-x-...item41835980f5They're made differently from the usual blades/wheels.  The abrasive is bonded without those big fiber chord things running thru the wheel.  Because of this, the wheel runs super smooth, and won't snag, and tear, if you bounce the saw accidentally on the steel.  AND, because they run so smooth, it's possible to run your saw for years without wearing out bearings.  They're the best out there.  Sometimes you can find these with the Brown label (made in Taiwan), and they're very much cheaper and the same quality as the Japanese version.For hand grinders, the Flexovit wheels are very good.  http://www.ebay.com/itm/Flexovit-Raz...item41891e38cf  I tried some HF cutoff wheels, and they had a tendancy to disintegrate.  On these you want to buy American made.  Flexovit is about the best."Any day above ground is a good day"http://www.farmersamm.com/
Reply:thanks for the links,if you are cutting massive 4x6" steel tube or something that requires a 14" ABRASIVE blade than I'm sure those are great, but most of the stuff I cut is 1.5" square or less. I'm sure a lot of hobbiest are in the same boat.Problem with big blades is they need to be made thicker so they don't deflect. If you're blade is twice as thick  you cut twice as much metal, make twice as much dust, etc. I've always been surprised that metal saws have such huge diameters compared to wood saws. If anything the average Joe is more likely going to cut big pieces of wood vs big pieces of metal.

Reply:I just bought a 7" diameter diamond blade that is .060" thin kerfI'll try to do a comparison test between them all. My theory is that the increase in surface speed is negated by the 100% increase in the amount of friction and metal cut. In other words ,what good does it do to double the surface speed from 7" dia to 14" dia if you also wind up doubleing the blade width and wind up cutting twice as much making more heat and friction?
