1. KEY FEATURES: - Application Suitable for polishing hard steel, balls, stones, and ceramic glass. - Material This diamond file is forged from high quality tool steel, which has high hardness, wear resistance, and is not easily deformed.Nickel plating is applied to the surface to prevent rust. - Features High temperature quenching treatment, fine grain, resists corrosion, and has excellent technology.A special manufacturing process is used to fix the grains of goldstone, improving adhesion, grinding and abrasion resistance, and polishing precision, making the file wear-resistant and durable.Good heat dissipation performance prevents the workpiece surface from overheating during polishing, causing heat generation, discoloration, and leaving glue residue. - Note ① Use one side of the new file, and wait until one becomes dull before using the other.② Please keep the file clean after use.Otherwise, it will affect the usage experience and durability.③Diamond files are widely applied to hard metals, but not to soft metals.For example: copper, aluminum etc. - Package Diamond file *10 pieces

2. PRODUCT DESCRIPTION: Wolfride File File Set Plastic Model Metal Model Woodworking Diamond File Tool Kintsugi Rust Removal Polishing Special Shape DIY Diameter 3mm x Total Length 140mm Set of 10 Features: Diamond files have extremely high hardness and wear resistance: Diamond is the hardest substance discovered in nature.Diamond files have a very low coefficient of friction: the coefficient of friction is low, the deformation is small during processing, and the cutting force can be reduced.Diamond files have high thermal conductivity: Diamond's thermal conductivity coefficient and thermal diffusivity are high, cutting heat is easily dissipated, and the temperature of the cutting part of the file is low.Diamond files have a low coefficient of thermal expansion: The coefficient of thermal expansion of diamond is several times smaller than that of hard metals, and the change in size of the file due to cutting heat is small.Specifications: Diamond file length: 140mm Diamond coating length: 25mm Shaft diameter: 3mm File head condition: Diamond coating Material: Alloy + Diamond grains Package: 10 x Diamond files
