My Borizon wheel is steel with the borizon along it's circumference.
Thanks for the info. Are my wheels safe?
Checked ours out at work today yours sound fine.
The metal backed wheels (I forgot about aluminum hubs) are diamond impregnated and you should be fine with these.
The problem wheels are ones that look similar to bench grinder wheels in their construction, ie made of sand like substance (silicon) and diamond or carbide chips. The silicon carbide and silicon diamond wheels have a green apperance and must look this way by law, hence the name "green wheels".
The silicon and carbide form a hazardous dust that cant be expelled from your lungs.
Ie if you breathe it you own it for life.:help:
