Review on 🧱 Dremel 952 Aluminum Oxide Grinding Wheel by Justin Peck

These aluminum oxide bits are great for grinding metal. I used two 952s and a 932 to fix the cast iron base, they cut through it like butter. At 22,000-25,000rpm you get better control but coarser sanding, but at 30,000rpm you can get really smooth and fast removal. A little higher and the bit loves to run away from you. I figured cast iron would eat up these pieces in no time, so I ordered 3 of each. The work was finished with only 2 + 1.
