@Brad93, yeah have known about pferd abrasives for a while after seeing the Bob Moffatt video on them, but a tad expensive for what I want, but thanks anyway
Are you after a carbide burr - the sort with teeth? Or are you after abrasive stones for die grinding?
The Pferd burrs aren't expensive when you're needing to chew up a load of metal.
No idea about silicon carbide, I'd personally just buy whatever I could find since they don't last long anyways.
