Tungsten carbide rotary file’s processing efficiency is several times higher than file, nearly 10 times higher than small wheel stalk. In a great part of the work, it can replace the petiole small wheel, without dust pollution, to improve the working environment. Its durability is 10 times higher than high-speed steel cutting tool, 200 times higher than small grinding wheel. It is easy to use, safe and reliable, to reduce labor intensity. It is packed with nice plastic case for safety storage and protection.
