Review on 🧶 ATOPLEE 10pcs 3.86'' 98mm Wool Polishing Buffing Wheel Pad for Angle Grinder Rotary Tool - Abrasive Grinding by Travis Rio

This is a lot cheaper than the next cheap option. I was looking for a $12 branded notepad but decided to give these a try. I'm glad I did! They're not as big, strong, and thick as branded 4.5" drives, but they're cheap enough that you can stack them and assign each a separate connection to avoid cross-contamination! The batch I bought has burned out, I will buy more. For reference, I used them on a Milwaukee 4.5 inch variable speed grinder. They fit over the mandrel threads and are tightened with the fixed nut, but do not go through the shoulder of the fixed nut. This wasn't a problem, but I had to use a thinner solid nut on one of the grinders so there was enough thread to tighten the collet nut.
