CONFORMABILITY – Strong yet flexible bristles conform to the contours, cracks and corners of irregular, curved and complicated shapes as easily as they do flat surfaces. Especially great on: Machined Parts, Turbine Blades, Threads & Engine Parts. SAFE – Eliminates hazards of traditional wire brushes. Safer and more efficient bristles that do not load up from debris, rubber, or plastic residues from metal surfaces, eliminating cross contamination. CONVENIENT – Pre-assmebled multi-ply wheel for more efficient operations TC BRISTLES -Thinner flexible bristles are curved for greater conformability. Requires less manipulation; conforms to contours, cracks and corners of irregular, curved and complicated shapes as easily as they do flat surfaces. ASSORTED SET – Includes 1 of each texture, to tackle a wide range of finishes. Coarser grits for light deburring and cleaning, standard grits for smoothing, and finer grits for finishing and polishing.
