American pattern files are large-sized file with uniform cut. They are primarily used for fast, controlled removal of material for shaping, deburring, and finishing applications.
Key files are small files for light, delicate filing tasks, especially in tool- and die-making. Also commonly used on locks and keys, they are well-suited for electricians, mechanics and anyone engaged in precision work.
Three Square Files are triangular in cross-section, like Tapers, but are double cut and have fairly sharp corners that are slightly set and cut. These files are for general use by machinists for filing internal angles more acute than the right angle,
