Diamond needle files

Needle files are also available in diamond versions: precision tools coated with diamond powder, ideal for finishing, smoothing, and shaping extremely hard materials such as hardened steel (>60 HRc), carbide, ceramic, glass, and marble. Essential in mechanics, jewelry, and molding, they offer high precision on complex geometries and irregular surfaces such as pillar, round, halfround, three-square, square, pointed, and other shapes.
