Needle Files

Also called a triangular file, the sides of Three Square Needle Files gradually taper to a point. All three sides are double cut. When used along a corner of the file, they will create a V-groove with a 60° angle. Useful for filing or refining seats in prongs.

Square Needle Files gradually taper to a point, with all four sides double cut along their length. They are a good general purpose file with many uses, including scoring lines for bending 90° angles, refining slot corners, and making round holes >into square holes.

Round Needle Files gradually taper to a point at their ends and are double cut along their entire length. Used to enlarge holes, file bevels on curved edges and to round off radii.

Knife Needle Files are best suited for filing grooves and getting into narrow slots, keyways and acute angles. The sharp profile has teeth on two sides with a safe top edge. Width and thickness taper to a fine point.

With one curved and one flat surface, Half Round Needle Files are well-suited for many applications, including removing material from the inside and outside of curved surfaces. They're is tapered in width and thickness and come to a point, allowing them to get into tight areas.

Equalling Needle Files have a rectangular profile with parallel sides and thickness. All four sides have teeth: double cut on top and bottom, single cut on both sides. They are used primarily for filing slots and corners but also make a good general purpose file due to a wide flat cutting surface.

Crossing Needle Files are similar in profile to a half-round file and is used primarily for filing interior curved surfaces and compound curves. They have two curved surfaces, one having a larger radius than the other. Both surfaces are double cut.

Crochet Needle Files are similar in shape to Warding Files, but they have round edges instead of flat. They are used in filing junctions between a flat and curved surface and for creating slots with rounded edges. Double cut top and bottom with single cut sides.

Oval Needle Files taper gradually along their length and can be used to file grooves of different diameters depending on which portion of the file you use. The differering radii of the broad sides and edges provide even more felxibility.
