SALI 9 Pack Nylon Filament Abrasive Wire Brush Wheel & Cup Brush Set with 1/4 Inch Hex Shank, 3 Sizes Nylon Drill Brush Set for Removal of Rust Corrosion Paint

This set of useful sanding tools contains brushes of three different sizes and three different roughnesses. These robust brushes are made of twisted steel wire coated with different colored nylon and abrasive grit. In normal restoration, work is started with the largest and roughest tool that is applicable and proceeds to the finer and smaller tool to clean up scratches made earlier. Abrasive roughness is graded on a scale of the screen mesh that would pass the stated grit. Coarse construction sand is 40 grit and auto repair finish is created with 400 grit. The normal order of usage of these tools would be grey brush, 80 grit, red brush, 120 grit followed by blue brush 240 grit. In practice these brushes cut more aggressively than labeled because the bristle tips have fine steel wire projecting from the ends of the plastic covering. As the plastic wears off, the effective grit approaches single digits. The hex shaft is particularly handy as it fits into flex shaft tools. The hex shaft allows counter clockwise rotation without loosening the chuck. I plan to continue using these brushes for restoration of steel auto and boat parts. Highly recommended.

Ive not actually had a need to use this item yet, so I cant really say much about its performance. I ordered this item because this is one of those tools that people dont tend to have on hand until they actually need one even though there is a very good chance at some point most people will need it. So instead of waiting until I need it and risk not being able to afford it at that time I went ahead and got it first so it will be on hand when I do need it. It appears to be well made out of quality materials and Im confident it will perform as expected when I do need it.
