10Pcs 5 X 180Mm Diamond Needle Half-Round File 120 Grit, Gold

The diamond file features high hardness, excellent bending strength and outstanding rust resistance; its surface is electroplated, firmly securing the diamond abrasive onto the alloy steel blade. Compared to other white sand material files, the diamond-made one have a brighter shine and are more durable. With uniform particle distribution, the file teeth are sharp and clear, providing strong cutting force while being resistant to wear, and can polish a variety of hard materials. When using, the file should be moved smoothly in a straight line or curve to ensure the file surface is evenly conforming to the workpiece surface. Diamond hand file is widely used in various scenarios, such as polishing jade, agate, wooden handicrafts, resin crafts, plastics, metal model parts, removing burrs from stainless steel accessories, aluminum alloy components, glass, etc., to meet your different needs. Please do not use a file as a pry tool to prevent the blade from bending, breaking, or the cutting edge from cracking, which may cause safety hazards and tool damage.
