American pattern trianguler file.

American pattern trianguler file also known as a three-square file, is a specialized tool designed for trimming and sharpening edges. Shaped like a triangle with 60-degree angles, it is ideal for filing V slots and working on square and rectangular tasks with angles between 60 and 90 degrees. Excellent for cleaning out corners or for use on cutters, taps and flat surfaces. Three-Square Files are double cut and taper toward the point in width and thickness, and feature the exclusive “Wavy Tooth” design.

Teeth of Hand Files

Single Cut

Single cut is a file tooth arrangement where a series of parallel teeth run diagonally across the width of the file. It is used for sharpening saws and for finishing work.

•  Single set of parallel, diagonal rows of teeth
•  Single-cut files are often used with light pressure to produce a smooth surface finish or to put a keen edge on knives, shears or saws

Double Cut

Double cut is a file tooth arrangement formed by two series of parallel teeth running diagonally across the width of the fi le with one series crossing over the other. It is used for fast stock removal.

•  2 sets of diagonal rows of teeth
•  Second set of teeth cut in opposite diagonal direction and on top of the first set
•  First set of teeth is known as the overcut, second is known as upcut
•  Upcut is finer than overcut
•  Double-cut file is used with heavier pressure than the single-cut and removes material faster from the workpiece

Rasp Cut

Rasp cut is a file tooth arrangement where a series of individual raised round teeth are formed by a single pointed punch tool. It is used for fast and rough cutting of wood, leather, hooves, and soft metals.

•  Series of individual teeth which are formed by a single-pointed tool
•  Produces a rough cut that is used primarily on wood, hooves, aluminum and lead

Curved Cut

Curved cut is a file tooth arrangement where a series of teeth are mill cut in curved contours across the width of the fi le. It is used for fi ling soft metals, plastics and where chip removal is required.

•  Teeth arranged in curved contours across the file face
•  Curved-cut file is normally used in automotive body shops for smoothing body panels

Length of Hand Files

As illustrated above, American pattern file lengths do not include the tang. Swiss pattern file lengths do represent the overall length.
