Why Use Rotary File

1. processing of cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum and other metals, and nonmetals such as marble, jade and bone.
2. can largely be replaced with a small grinding wheel, and no dust pollution.
3. high efficiency. Processing efficiency than the manual file dozens of times times, than with a small grinding wheel nearly 10 times.
4. processing of high quality, high quality finish. Can process a variety of high-precision shape of the mold cavity.
5. long life. Improve durability than HSS 10 times, than smaller wheels increased by more than 200 times.
6. easy to use simple, safe and reliable.
7. the use of high efficiency, processing costs can be reduced by dozens of times times.
