Generally, this rotary file set can replace a small, handle-mounted grinding wheel. Cutting is easy, safe, and durable. [Extra-Long Lifespan]: Packaged in a plastic box for safe storage and comprehensive protection. The lifespan of these heavy-duty rotary cutting tools is 10 times that of high-speed steel and 200 times that of a grinding wheel. Rotary tools typically operate at speeds between 6,000 and 50,000 revolutions per minute, reducing bearing wear and extending the overall lifespan of the tools.
