Diamond files for hard materials

A diamond file works materials that are too hard for an ordinary steel file: glass, ceramics, hardened steel, carbide, gemstone and composite. Instead of cut teeth, the file blade carries a layer of diamond grit that abrades the material rather than cutting it. That lets you file, grind and fit hard surfaces accurately without chipping.

Toolmakers, jewellers, tilers and model makers use them for fine finishing and for deburring sharp edges. Diamond needle files are slim and taper to a point for work in narrow recesses, while wider workshop files remove more material in a single stroke. Brands such as Pferd and Bahco offer them in various grit grades, from coarse for fast removal to fine for a smooth finish.

When choosing, look at the shape, flat, round, knife or triangle, and at the length, here from roughly 100 to 215 mm. Work with light pressure and keep the diamond file clean, because diamond grit wears faster under excessive force. This way you work the hardest materials with control and precision.
