What it’s used for:
This is the "flat wheel" version vs the "cup" version you sent before. Both do heavy-duty cleaning, but the wheel is better for flat surfaces and edges.
Main jobs:
1. Rust + scale removal from steel plates, beams, pipes
2. Stripping paint/coatings - removes old paint fast without chemicals
3. Weld slag + spatter cleanup after welding
4. Surface prep before painting/coating - gives metal a rough profile so paint sticks
