PIES 63460T Silicon Carbide Grinding Thickness Review

I installed this circuit on my grinder and turned it on. After 5 seconds it exploded and hit me in the head. Immediate emergency visit! Poor quality would be the understatement of the year. This product is dangerous, do not buy it.

After being adjusted and then straightened with a diamond tool, this green wheel begins to vibrate, causing the grinder to vibrate against the table. Completely useless. No problem with my other wheel or any other grinding wheel. looks like a manufacturing defect. The video shows it rotating and vibrating. When I started this I thought the vibration would go away after putting it on, no. I contacted the seller and asked for a refund.

I wanted it to sharpen carbide bits. It appears to be green silicon carbide designed for carbide, but the packaging doesn't list anything. (I have to say there wasn't anything in English on the box either.) I've only used it a couple of times and it works with carbide bits, but the gray wheel on the other end of the grinder works just as well. I use it and will try again sometime.
