Review on 🔸 BHA 4.5-inch x 7/8-inch Aluminum Oxide Resin Fiber Sanding and Grinding Discs, 60 Grit - 25 Pack by Sri Mims

Discs are useless. The 24 grit aluminum oxide deposits just fly off when you start grinding the metal. This disc was used to prepare mild steel for welding, after only a few passes the disc would not cut, I looked at the disc and found the following, only the substrate remained, all of the cutting or grinding surface was gone. Tried another drive, got the same result and performance. Useless! Another example of very poor quality. The item was made in TURKEY. save your money
