140MM*3MM Diamond Grinding Pins / High quality grinding tools
Suitable for precision machining, ABS mold, metal blade and ceramic grinding, the surface has embedded small particles of industrial diamonds, using diamonds in this way to make the file more efficient use, harm the work is extremely difficult.
Using a diamond in this manner enables the file to be effectively applied to very hard materials, such as stone, glass, or very hard metals (such as hardened steel or cemented carbide). Standard steel files are not effective.
The diamond file is also the only type that can be used to reciprocate without damaging the file.
