File, FleX ible, Plastone, 1/2 in X 4-3/4 in X .080 in, 120-Medium Doz.
These files are useful wherever fine finishing is needed and they are impervious to oil and water; accumulations of grease can be washed with soap and water. Since the files are non-conductive, they are popular for dressing automotive, electrical, and electronic contacts. Plastone fleX ible files are made of hard abrasive materials pressed into a fleX ible core.
