Three Square Files

Three square files are triangular files that are double cut on the sides, single cut on the edges, and can taper toward the point in width and thickness. The angles on three square files are 60 degrees, and they are very useful for corners and on dies. The coarseness of the file indicates the spacing of the teeth and the number of teeth per inch; the our different grades for American Pattern Files are coarse cut, bastard cut, second cut, and smooth cut. (In that order from fewest to most teeth per inch) The coarseness of the file also depends on the length from point to heel. Shop our online selection or contact us today for a custom quote.
