Review on 🔧 9Pcs Brass-Coated Wire Brush Wheel & Cup Brush Set with 1/4-Inch Shank - 9 Sizes Coated Wire Drill Brush Set for Rust, Corrosion, Paint Removal - Enhanced Durability, Reduced Breakage, Longevity by Skyy Strickland

They are very tight but not quite 1/4" shanks, maybe on the 16th but it matters a little when you put them on the Lay the grinder....Lots of bristles sticking out everywhere and of varying lengths.It's not entirely uncommon for a few to be bent or deviated,but they had a lot more than a few.In general I think they work well , if you trim the random elements first and only use them in practice otherwise not so good I wish I would have given more stars but even 3 was a boost for them.
