Anyone have experience with this cut off wheel? I'm in the market for a new one and IR calls this a heavy duty one. My previous ones are all sub .5 HP and haven't seemed to last too long. The one I have now seems to be rough like a bad bearing. My other one gets stopped doing regular work. I know there are a lot of HD ones out there but I don't want to spend $200 and it needs to run off of a regular home compressor. I've got about 35 gallons and 6 cfm to work with.
