Review on Cubitron 982C Precision Ceramic Diameter by Craig Walters

Simply the fastest grinder I've seen to remove welds in sheet metal to make it flat. Lasts a lot longer than I thought. Metal splinters/dust are flying around so wear a respirator and safety goggles. Now look for the equivalent of this to use in tighter spaces, as it's good for flat and open areas, but a large 4.5-inch grinder won't fit in tight spaces or work well on uneven surfaces - neither Grinding edge like a fixed hard grinding wheel so you can't rotate the edge to get to a narrow area. In flat, open areas you might think it was wood and not steel as it disappears so quickly.
