American Pattern File Round     
Round - American Pattern File Intended for enlarging and rounding out circular openings or concave surfaces. Round Files are double cut and taper toward the point in width and thickness. (Round Files are often referred to as "Rat Tail" Files.)

Machinist Files, generally double-cut, are excellent for hogging (rapid stock removal) on all types of material.

Saw Files, generally single-cut, are great for smoother finishes and best suited for sharpening saws or dressing edged tools.
