9Pcs Stainless Steel Wire Wheel & Cup Brush Set with 1/4'' Round Shank 0.0118In Coarse Crimped Carbon Steel Drill Brush for Drill Removal of Rust/Corrosion/Paint

I was looking for smaller wire brushes to fit into nooks and crannies to clean up after welding. These are a great set of sizes and shapes, and only the two largest brushes duplicated brushes I already had.They are very robust! I really had to abuse them to clean out the heavy build up, twisting and forcing to get into tight spaces between steel parts. Not a single bristle failed! In the past I have always had small wire brushes fall apart under less abuse than this. Surprised and pleased with the quality.
