A diamond particle file with a titanium-coated surface.
Titanium coating improves hardness and rust resistance, and with this high hardness, it can cut and engrave not only plastic model parts but also metal parts such as etching.
For plastic parts, it can be roughly finished; for metal parts, it can be used for finishing processes, equivalent to #400 grit.
Available in three shapes—flat, domed, and round—it is useful in various scenarios in plastic model making.
